Mix Rules: Vitamin C, AHA/BHA/Retinol | Find the Best Ingredients Layering for your Skincare Routine

Can you use mandelic acid every day?

Yes, you can, as long as you’ve built your skin’s tolerance to it, especially if you have a skin type is dry and prone to sensitivity. The way you build the skin tolerance is by firstly performing a patch test as this will help you determine how effect the ingredient will be for you and your skin.

The molecular size of mandelic acid is very large, meaning it’s unable to penetrate too far down the skin compared to other acids, such as salicylic acid or glycolic acid. This helps mandelic acid work on the outer layers of the skin helping bring new skin cells to the surface acid leaving the complexion, glowing, healthy, and happy.

How to Layer: Acid + Active Combinations That Pack A Punch

Curious about our topical acids, but not so sure how to incorporate them into your skincare routine? We hear you. Our newest acids are power-packed with ingredients that target serious concerns, and can be layered with other actives for maximum benefits. Read on to learn about some of our favorite combinations.

THE SCIENCE BEHIND IT…OVERALL CLINICAL DATA ON SPECIFIC INGREDIENT(S) & HOW THEY FUNCTION:

Acids can easily be incorporated into any skincare regimen, working for all skin types and skin concerns. Many skincare actives and acids compliment each other, working on different biological mechanisms to treat similar skin concerns, with synergistic results. This means addressing your skin concerns in a more comprehensive way and combining products that can enhance the efficacy of each other.

Understanding Mandelic Acid and Vitamin C

Mandelic acid and vitamin C are two common skincare ingredients that can be combined to provide a variety of benefits. Mandelic acid is a bitter almond-derived alpha-hydroxy acid (AHA). Because it has a larger molecular size than other AHAs, it is gentler and less irritating to the skin. Mandelic acid is well-known for its exfoliating properties, which can aid in the improvement of skin texture and tone, the reduction of fine lines and wrinkles, and the evenness of skin discoloration.

Vitamin C, also known as ascorbic acid, is a powerful antioxidant that can aid in the protection of the skin from environmental stressors such as UV rays and pollution. It is also well-known for its brightening and anti-aging properties, as it can help reduce the appearance of dark spots and fine lines while improving overall skin radiance. When combined, the advantages of mandelic acid and vitamin C can enhance one another’s effects to produce a more radiant and youthful complexion. But as with any combination of skincare ingredients, it’s important to comprehend each ingredient’s unique qualities and compatibility, as well as how to use them correctly and safely.

Mandelic Acid: A Gentle AHA for Skin Exfoliation

Mandelic acid, as previously stated, is an alpha-hydroxy acid (AHA) derived from bitter almonds. Mandelic acid has a larger molecular size than other AHAs such as glycolic acid and lactic acid, which allows it to penetrate the skin more slowly and gently. Because of its gentle exfoliating properties, mandelic acid is an excellent choice for those with sensitive skin who are more prone to irritation and redness when using stronger AHAs. Mandelic acid can aid in the removal of dead skin cells from the skin’s surface, improving skin texture and tone, reducing the appearance of fine lines and wrinkles, and evening out skin discoloration.

Mandelic acid also has antibacterial properties, which may be beneficial to those with acne-prone skin. It can aid in the unclogging of pores and the prevention of new acne lesions. Overall, mandelic acid is a good option for those who want to incorporate an exfoliating ingredient into their skincare routine but are wary of using stronger AHAs. However, before incorporating it fully into your routine, start with a low concentration and a patch test.

Vitamin C: A Potent Antioxidant for Skin Brightening

Ascorbic acid, also known as vitamin C, is a powerful antioxidant that can help to brighten and even out skin tone. It works by preventing the production of melanin, which causes dark spots and uneven skin pigmentation. Furthermore, vitamin C can help to protect the skin from environmental stressors such as pollution and UV radiation, both of which can contribute to the appearance of ageing. When applied topically, vitamin C can also stimulate collagen production, improving skin firmness and reducing the appearance of fine lines and wrinkles.

It is critical to understand that not all forms of vitamin C are created equal. The most commonly used form of vitamin C in skincare is L-ascorbic acid, which has been shown to be the most effective at increasing collagen production and brightening the skin. It is, however, the most unstable form and can oxidise quickly, making it less effective over time. Other forms of vitamin C, such as ascorbyl glucoside and magnesium ascorbyl phosphate, are more stable and less likely to irritate the skin, but they may be less effective overall. For maximum efficacy, look for a vitamin C product with a stable formulation and a high concentration of L-ascorbic acid. To prevent oxidation, vitamin C products should be stored away from heat and light.

Individual Benefits of Mandelic Acid and Vitamin C

Mandelic acid, as previously stated, is a gentle alpha-hydroxy acid that can help exfoliate the skin and improve texture and tone. Some of the specific benefits of mandelic acid include reducing the appearance of fine lines and wrinkles, improving skin texture and tone, treating acne and hyperpigmentation, minimising the appearance of pores, and reducing the occurrence of ingrown hairs. Vitamin C, on the other hand, is a powerful antioxidant that can help to brighten the skin and improve overall skin health. Some of the specific benefits of vitamin C include reducing the appearance of dark spots and hyperpigmentation, stimulating collagen production for improved skin firmness and elasticity, protecting the skin from environmental stressors such as pollution and UV radiation, improving skin texture and tone, and reducing inflammation and redness. Incorporating both mandelic acid and vitamin C into your skincare routine can aid in the treatment of multiple skin concerns and the overall health of your skin. However, they must be used in a safe and effective manner, as overuse or improper use can cause irritation and other side effects.

Can you use AHAs and vitamin C together?

The simple answer is: It depends. Due to their individual pH levels, AHAs and vitamin C are very tricky to formulate together in a single product (although it can be done — more on that here). The workaround is to layer your AHA and vitamin C skincare products. (AHAs go first.) But if your skin is prone to sensitivity, you’re better off using your AHA and vitamin C items at different times of day.

HOW DO I USE MANDELIC ACID TREATMENT?

As an AHA, we recommend using this in the PM of your routine after cleansing and hydrating and followed by serums and moisturizers.

It is compatible with other AHAs such as Alpha Hydroxy Acid, Glycolic Acid Toner, Lactic Acid and Apple Cider Vinegar, as well as Vitamin C and Retinol Serum. If using alongside Retinol Serum, be aware that this formula contains Retinol and you may need to adjust frequency of use or alternate days of use and build up the skin’s tolerance.

If you are wanting to add Mandelic Acid to your routine (or any other new product), we recommend patch testing. Apply a small amount of the product on dry cleansed skin behind the ear or on your inner arm. Wait at least 24 hours to see if any irritation occurs. If you notice any irritation such as redness, itchiness or burning, rinse off and discontinue use. Please note, it can take up to 72 hours for a reaction to present itself.

We recommend you consult a doctor or dermatologist if you’re unsure of compatibility with any prescribed skincare products.

What toner should I use before vitamin C serum?

You can use any toner before vitamin C serum, the important factor to remember is ensuring you leave enough time between applications. Leaving this amount of time will also help the pH levels rebalance therefore avoiding skin irritation, redness, and itching.

You’ll also find that using a toner which contains an exfoliating acid will slough away the build-up of dead skin cells and flaky patches of skin, both of which often act as barrier preventing other ingredients from penetrating.

What is vitamin C?

Although best known as an uber-powerful antioxidant, vitamin C does more than neutralize free radicals. It also helps stimulate the production of new collagen to keep skin firm and smooth. Used consistently, vitamin C also helps minimize the look of dark spots, hyperpigmentation, and uneven skin tone by reducing melanin production. And vitamin C helps fortify skin’s barrier function, so that less water can evaporate, and the tissue remains healthy and hydrated.

Can You Use Mandelic Acid and Vitamin C Together?

Yes, you can use mandelic acid and vitamin C together in your skincare routine. In fact, their effects can complement each other to provide a variety of skin benefits, such as brightening, improving skin texture and tone, and reducing the appearance of fine lines and wrinkles. However, these ingredients should be introduced gradually and carefully, as overuse or improper use can cause irritation and other negative effects. When using these ingredients together, it’s also important to consider their compatibility and pH levels, as they may interact with each other and reduce effectiveness if not properly formulated.

Always patch-test new products and consult with a dermatologist or skincare professional before incorporating new ingredients into your routine, especially if you have sensitive skin or any underlying skin conditions.

Assessing Ingredient Compatibility

The compatibility of ingredients is an important step in incorporating mandelic acid and vitamin C into your skincare routine. Here are some things to think about:

  1. pH levels: Mandelic acid works best at pH levels between 3 and 4, whereas vitamin C works best at pH levels between 2.5 and 3.5. As a result, it’s critical to use products containing these ingredients that have a pH level within their optimal range to ensure their effectiveness.

  2. Concentration levels: Lower concentrations of both mandelic acid and vitamin C can be effective, but higher concentrations can cause irritation or other side effects. It is critical, to begin with, low concentrations and gradually increase them as your skin becomes accustomed to the ingredients.

  3. Formulation: It is also critical to consider the formulation of the products you use. Water-based vitamin C products, for example, may not mix well with oil-based mandelic acid products. It is best to use products that have been designed to work well together.

  4. Skin type: These ingredients may cause different reactions in different skin types. Sensitive skin, for example, may be more prone to irritation from high concentrations of mandelic acid or vitamin C. Before incorporating these ingredients into your routine, consider your skin type and any underlying skin conditions.

It’s critical to start slowly and monitor how your skin reacts to these ingredients. If you experience any irritation or negative effects, stop using the product and consult with a dermatologist or skin care professional.

Benefits of Combining Mandelic Acid and Vitamin C

Combining mandelic acid and vitamin C in your skincare routine can provide your skin with a variety of benefits, including:

  1. Improved skin texture and tone: Both mandelic acid and vitamin C exfoliate the skin, revealing smoother, brighter skin. Mandelic acid works by gently dissolving the bonds between dead skin cells, whereas vitamin C stimulates collagen production, improving skin texture and tone.

  2. Reduced hyperpigmentation and dark spots: Vitamin C is a powerful antioxidant that, by inhibiting melanin production in the skin, can help to reduce the appearance of dark spots and hyperpigmentation. Mandelic acid can also aid in the reduction of hyperpigmentation by increasing cell turnover and removing dead skin cells containing excess pigment.

  3. Anti-aging benefits: By stimulating collagen production in the skin, both mandelic acid and vitamin C can help to reduce the signs of ageing. Collagen is a protein that helps keep skin firm and elastic, and its production declines with age.

  4. Improved product absorption: Combining mandelic acid and vitamin C can help to improve the absorption of other skincare products in your routine. Mandelic acid exfoliation can help remove dead skin cells that can clog pores, and vitamin C can help increase the penetration of other skincare ingredients.

Using mandelic acid and vitamin C together can help to improve your skin’s overall health and appearance, leaving it brighter, smoother, and more youthful.

How to Incorporate Both Ingredients into Your Skincare Routine

Here are some suggestions for incorporating mandelic acid and vitamin C into your skincare regimen:

  1. Start with thoroughly cleansed skin: Make sure your skin is thoroughly cleaned before using any skincare products.

  2. Use mandelic acid first: If you intend to use both mandelic acid and vitamin C in your routine, use the mandelic acid product first. This enables it to enter the skin and carry out its exfoliating function.

  3. Wait before applying vitamin C: Wait a few minutes after applying mandelic acid before applying your vitamin C product. This gives the mandelic acid time to work and avoids any irritation that could result from layering products too quickly.

  4. Use vitamin C in the morning: Vitamin C helps shield your skin from environmental stressors, making it a great ingredient to use in the morning. After mandelic acid and before moisturiser and sunscreen, apply your vitamin C product.

  5. Start with lower concentrations: To prevent irritation, start with lower concentrations when using mandelic acid or vitamin C for the first time. As your skin adjusts, gradually increase the concentration.

  6. Use sunscreen: Mandelic acid and vitamin C both make your skin more susceptible to sunburn, so it’s crucial to wear sunscreen during the day.

  7. Patch test: It’s always a good idea to do a test patch on your skin before using any new skincare products. Apply a small amount of the product on a small area of the skin and wait 24 hours to make sure there’s no adverse reaction.

Tips for Safe and Effective Use of Mandelic Acid and Vitamin C

The following advice will help you use mandelic acid and vitamin C safely and effectively:

  1. To ensure there won’t be a negative reaction, always patch-test a new product on a small patch of skin first.

  2. Start slowly and use new active ingredients like mandelic acid and vitamin C only once or twice a week at first to give your skin time to adjust.

  3. To avoid over-exfoliation and irritation, use mandelic acid and vitamin C on different days.

  4. Mandelic acid and vitamin C both have the potential to increase your skin’s sensitivity to the sun, so it’s critical to use sunscreen every day that has a minimum SPF of 30.

  5. Vitamin C and mandelic acid both have the potential to be dehydrating, so it’s crucial to apply a moisturiser after using them.

  6. Never deviate from the recommended usage guidelines and always adhere to the instructions on product labels.

  7. Consult a dermatologist or skincare expert if you have any concerns or questions about using mandelic acid and vitamin C. They can assist you in developing a customised skincare regimen that is suitable for your skin type and issues.

Identifying Your Skin Type and Concerns

It’s critical to understand your skin type and concerns before incorporating any new skincare ingredients. This will assist you in selecting products that are best suited to your skin and maximising their benefits. Here are some broad principles for determining your skin type:

  1. Normal skin has a uniform texture, balanced moisture levels, and little sensitivity or acne.

  2. Dry skin has a tight, flaky texture, and is dull, tight, and more sensitive.

  3. Large pores, a shiny appearance, and a higher chance of breakouts are all symptoms of oily skin.

  4. Dry and oily patches of skin on the face, such as an oily T-zone and dry cheeks, are examples of combination skin.

  5. Skin that is sensitive is often irritated, scratchy, or prone to rashes.

Look for any of the following to pinpoint your unique skin concerns:

  1. Acne or breakouts

  2. Ageing or wrinkles

  3. Dark spots or uneven skin tone

  4. Dryness or dehydration

  5. Redness or inflammation

You can select skincare products and ingredients that are specifically suited to your needs once you have a clear understanding of your skin type and your skin-related issues.

Introducing Mandelic Acid and Vitamin C Gradually

When incorporating mandelic acid and vitamin C into your skincare routine, begin slowly and gradually increase usage. This will allow your skin to adjust to the new products and reduce the likelihood of irritation or sensitivity. Begin by applying mandelic acid or vitamin C to your skin once or twice a week, preferably at night. If your skin tolerates it, you can gradually increase the frequency to every other night and, eventually, every night.

Before applying the products to your entire face, it’s also a good idea to perform a patch test on a small area of the skin. This will assist you in determining whether your skin is reacting negatively to the ingredients. Also, make sure to follow the instructions that come with the products, as they may differ depending on the brand and formulation. Finally, use sunscreen during the day because mandelic acid and vitamin C can make your skin more sensitive to the sun.

Balancing Active Ingredients with Hydration and Skin Barrier Care

It’s critical to balance active ingredients like mandelic acid and vitamin C in your skincare routine, as well as hydration and skin barrier care. Because active ingredients can sometimes cause dryness or irritation, it’s critical to keep your skin’s moisture and barrier function intact. After applying mandelic acid or vitamin C, one method is to use hydrating products such as moisturisers or facial oils. This will aid in the retention of moisture and the prevention of dehydration in your skin.

To give your skin an extra boost of hydration, use a hydrating toner or essence before applying mandelic acid or vitamin C. Look for humectants, such as glycerin or hyaluronic acid, which can attract and retain water in the skin. You may also want to use a gentle, non-foaming cleanser to avoid stripping your skin of its natural oils. This can aid in the maintenance of your skin’s barrier function and the prevention of dryness and irritation. Remember to wear sunscreen during the day because UV rays can damage your skin and compromise its barrier function. If you’re going to be outside, use a broad-spectrum sunscreen with at least SPF 30, and reapply it every two hours.

Mandelic Acid : What you need to know

Introducing your new hyperpigmentation hero – Mandelic Acid Treatment. A member of the Alpha Hydroxy Acid family, we’ve formulated this gentle treatment to target marks and scarring caused by breakouts as well as pigmentation concerns.

What is mandelic acid?

“Mandelic acid is an alpha hydroxy acid (AHA) that’s a common exfoliating ingredient in over-the-counter skin care products,” said board-certified dermatologist Mara Weinstein Velez, M.D. This acid is derived from bitter almonds and is often used to “address skin care issues such as dark spots, wrinkles, dullness, aging skin and acne.”

While other AHAs also serve as exfoliants, mandelic acid also works “to increase cell turnover by dissolving the bonds holding skin cells together. Given its larger molecular weight, it tends to be less irritating than other types of smaller AHAs such as glycolic acid,” mentioned New York-based board-certified dermatologist Tatyana Nektalova, M.D.

How to use AHAs with vitamin C for best results

You have two options when it comes to incorporating both AHAs and vitamin C into your daily skincare routine — together or apart. Here’s how:

Layering AHAs and vitamin C together

As noted above, if you decide to put one on top of the other, you should apply your AHA skincare first. This is because the AHA is an exfoliant, and you don’t want to smooth on your vitamin C serum, only to remove it immediately afterward with a swipe of your AHA. The other thing to keep in mind is that both ingredients can cause sensitivity — especially at high concentrations. To minimize the risk of irritation, if you’re using a potent AHA product (like a peel), be sure it incorporates a neutralizing step to “shut off” the acids. Otherwise, the active acids plus vitamin C could equal a red-faced result for you.

Using AHAs and vitamin C at different times

If you don’t want to run the risk of an inflamed outcome, apply your AHAs and vitamin C at opposite times of the day. Since vitamin C is an antioxidant, it makes sense to use it right before you’re going to be exposed to the max amount of free radicals — the daytime. (UV rays are a major generator of unwanted free radicals.) Your vitamin C products will provide extra reinforcement under your top layer of SPF 30. Then you can incorporate your AHA skincare into your pre-bed regimen. You’ll still get the benefits of both ingredients, but spacing them out will lessen the risk of a negative reaction.

What can you not mix with mandelic acid?

Although I have mentioned how gentle mandelic acid is, it still provides exfoliation to the skin and if used with the wrong active ingredients can result in several side effects.

The ingredients you should avoid mixing with mandelic acid, is other AHAs, such as glycolic acid, BHA, such as salicylic acid, especially if included with chemical peels, and retinol.

Can I use AHA and vitamin C together?

You can, but ensure you use them properly together to avoid unwanted side effects. There are a couple of different ways to team an AHA and vitamin C together effectively.

Option 1-

Apply the AHA first by using either a face cleanser or exfoliating toner, wait for about 10 minutes before applying a serum enriched in vitamin C. Ensure you leave enough time in between applications to counteract the risk of irritation, this is because the skin’s natural pH levels would have rebalanced and the skin become prepared for further applications.

Option 2-

Use an AHA enriched product and vitamin C product throughout different times of the day. many favours using vitamin C in the morning due to its antioxidant benefits and luminous finish it gives your skin. Follow this in the evening with evening with your AHA product, be it toner or serum to rid the skin of impurities and other build-ups.

If you are new to both ingredients, and you are planning on introducing a new product into your routine, I would suggest performing a 24-hour patch test before applying anything on the face.

Tretinoin / Retinol / Vitamin C / AHA / BHA / Niacinamide / Hydroquinone

2019 rồi, dưỡng da bây giờ không chỉ còn đơn giản là Rửa mặt – dưỡng ẩm – chống nắng nữa, mà còn , tầng tầng lớp lớp bao nhiêu là serum, bao nhiêu là đặc trị…Dù mình vẫn hay bảo nhau, giống ở đời vậy, nhiều khi mình tập chấp nhận cho dễ thở 1 tí nhưng con người mà, luôn có 1 cảm giác chưa bao giờ là đủ, chưa kể là sao nó cứ ập vào mặt mình, dâng tới tận miệng thì nhiều khi muốn không tham cũng uổng.

Chưa kể, tìm ra được một chất mà nó làm được cái gì đó thấy rõ ràng trên mặt mình người ta nói như mở 1 chiếc hộp pandora vậy. Bạn bị kích thích, và không thể chờ, chịu không nổi và muốn dùng cái này rồi dùng cái kia, nhưng….kết hợp chúng được không, dùng nhiều như vậy nổi không.

Tám vậy để link vào chủ đề hôm nay mình hy vọng sẽ giải đáp phần nào thắc mắc những con nghiện skincare hay những ai sắp dấn thân vào con đường đầy acid hay chất kích thích mạnh bạo này ^^ là muốn dùng thì kết hợp được không, kết hợp thế nào?

Và dĩ nhiên, các chất kích thích chúng ta mạnh bạo nhất hiện nay sẽ được đề cập trong bài:

+ RETINOIDS bao gồm cả tretinoin, retinaldehyde, hay retinol mà mọi người hay dùng nhất mà hôm nay mình sẽ chọn TRETINOIN làm chính đi hén, TRETINOIN mà bạn chịu được thì khỏi phải hỏi mấy bạn đàn em của nó nhé! Lưu ý là ngoài TRETINOIN, các phái sinh khác đều cần sự chuyển hóa khi muốn phát huy tác dụng trên da, nên là mình sẽ phân ra khi cần thiết là Tretinoin và Retinol (nhóm các chất phải chuyển hóa mà đại diện là Retinol)

+ VITAMIN C trong bài là thể mạnh nhất LAA – L Ascorbic Acid, pH~3. Còn lại các thể khác SAP, MAP…pH~6, bạn không phải ngại.

+ AHA – Alpha Hydroxy Acid bao gồm glycolic acidc, lactic acid, mandelic acid…

+ BHA – Salicylic acid

+ Niacinamide – Vitamin B3

+ Hydroquinone – chất làm trắng duy nhất được công nhận, còn tất cả các bạn nhẹ hơn như Arbutin, Kojic Acid… không phải ngại khi dùng chung.

Ok, let’s start!

Yes, absolutely! 2 bạn này dùng chung cực kỳ AN TOÀN nhé! Combo thần thánh này được đưa hẳn vào các quy trình làm trắng, sáng, trị nám, cải thiện sức khỏe làn da. Dĩ nhiên Hydroquinone vẫn có những điểm khó dùng và bạn phải theo nguyên tắc dùng cực kỳ nghiêm ngặt.

Keep C for the morning, save Tretinoin for the night!

Nghe thèm thuồng khi dùng C chung với Retinoids đúng ko? Và khi này chúng ta cần phân biệt các anh chị em của nhà Retinoids kỹ càng hơn.

+ Nếu bạn dùng hẳn TRETINOIN thì câu trả lời là dùng chung được.

+ Retinol hay các phái sinh Vitamin A khác cần chuyển hóa thành retinoic acid để phát huy tác dụng được.

Có 2 luồng ý kiến trái chiều song song hiện tại mà chưa bên nào có bằng chứng đủ để thuyết phục bên kia. Mình lấy ví dụ cả Obagi và Paula’s Choice đều có câu trả lời là YES nhưng Nicky của FutureDerm và rất nhiều các chuyên gia khẳng định không và nếu có thì hãy dùng cách nhau 30p (cái nào mỏng đi trước).

Một bên cho là thậm chí nghiên cứu còn chỉ ra được Retinol không những hiệu quả hơn khi dùng chung với Vitamin C mà còn tăng cường khả năng bảo vệ da rất rất nhiều. Nhưng cũng lý do người ta lo ngại và tin cho tới tận bây giờ là vì sự chuyển hóa của Retinol thành Retinonic acid cần sự thủy phân ở pH trung tính mà khi đưa axit vào sẽ làm pH giảm. Trong khi Vitamin C thì lại cần pH thấp để giúp C bền vững (pH của retinol là ~6, của C là ~3)

Câu trả lời của mình 2 chất này đều đáng đưa vào quy trình của bạn, nhưng tại sao phải take risk dùng chung 1 buổi. C dùng buổi sáng rất rất tốt, Tretinoin/Retinol/Bất kỳ Vitamin A nào dùng tối quá tuyệt vời, tại sao phải cố và dùng chung đúng không nè!

C buổi sáng thoải mái và Tretinoin tối nha bạn ơi!

AHA và BHA là axit nên câu trả lời của mình khá tương tự như trên nhé. Khác với Vitamin C là một chất chống oxi hóa, AHA và BHA có tính chất exfoliant (tẩy da chết) dù AHA và BHA cũng nhiều công dụng khác nữa nhưng hơn hết là điểm này, nên dùng chung AHA/BHA với tretinoin thì hơi mạnh bạo quá với da. Dẫu vậy, như mình nói, câu trả lời tương tự như trên Vitamin C và 2 luồng ý kiến vẫn đang tồn tại song song, lựa chọn là ở bạn, sức chịu đựng là của da bạn và nếu thật sự phải dùng, hãy cứ dùng tách buổi, tách ngày hoặc bạn rãnh thật sự thì 30p chờ đợi nhé ^^ Bạn không muốn mình như 1 con rắn cứ lột da hay đỏ da liên tục đâu.

This relationship works. Trên tất cả dùng Tretinoin / Retinol làm da thời gian đầu châm chích, khó chịu, kích ứng nhẹ. Niacinamide ngoài việc làm dịu da bạn lại còn hoàn toàn giúp tăng cường hàng rào bảo vệ da và làm được nhiều chuyện khác. 2% niacinamide lên da còn được chứng minh là y như bạn bôi petrolatum (vasaline) lên mặt vậy.

Perfect for each other! Sự kết hợp này gần như hoàn hảo đến một mức mà bạn sẽ tìm thấy dễ dàng những chai serum có hẳn AHA và Vitamin C trong 1 chai. Nếu chọn combo này dùng chung, tốt nhất với mình là giữ AHA + C cho tối, sáng thì dùng C là đủ rồi.

Tuyệt vời. Sự kết hợp này cũng không có gì đáng bàn cãi. Đầy ra đó những sản phẩm chứa hẳn 2 em này chung 1 chai hay dùng từng em lần lượt là lựa chọn của bạn. Duy nhất chỉ là da bạn có cần đến mức đó, có chịu nổi không thôi.

Tips here: Mình không ưng BHA dùng lâu dài nhất là khi da bạn hết mụn nhé! Chi tiết mình nói sau nhé 😊

Hydroquinone – hoạt tính được công nhận là chất làm trắng duy nhất hiệu quả an toàn hiện nay, sẽ hiệu quả thật sự và nhanh hơn khi bạn đi kèm với các axit có khả năng đẩy nhanh quá trình sừng hóa như tretinoin / BHA / AHA / LAA nên là bạn không phải ngại khi dùng chung gì nhé! Chỉ là da bạn ưa loại axit nào thì chọn loại đó. Như mình nói nhỏ bên trên, da bạn trên 30t, cần trị nám, không quá dầu không mụn, trừ khi da bạn phải là đặc biệt phản ứng tốt BHA chứ mình chưa thấy ai ưa BHA đến vậy đâu nhé!

Complicated! Phức tạp 1 tí. Nếu bạn có tìm hiểu và thật sự đọc nãy giờ thì vấn đề khi kết hợp các hoạt tính nằm ở độ pH. AHA/BHA/LAA có pH ~3, Niacinamide có pH ~5-6, niacinamide mà bị chuyển hóa thành Nicotin acid thì gây phản ứng đỏ da, một số trường hợp có những cảm giác bỏng nhẹ, ngứa, da nóng lên, dù không gây hại gì.

Riêng về LAA và Niacinamide thì thậm chí dù ở điều kiện tối ưu nhất thì cũng không có phản ứng 100% để tạo thành niacinamide ascorbate gây mất tác dụng hoàn toàn của bản thân LAA hay Niacinamide ^^

Tóm lại là cái đống combo này tội tình gì mình phải mạo hiểm dùng chung như vậy. Muốn thì Niacinamide sáng / còn lại đẩy tối nhé.

Haha, interesting! Nếu bạn tìm hiểu thì 5% Niacinamide tương đương cỡ 2% Hydroquinone. Niacinamide an toàn, dễ sử dụng, hiệu quả nhiều thứ khác cho da ngoài chuyện làm trắng giảm thâm nám như hydroquinone, nên là….Dùng chung cũng được, tùy bạn nhé, 2 em này không đụng nhau, chỉ là tác dụng khá giống nhau và cẩn thận không khéo bạn trắng ra quá hơn với cổ đó! Và, một lần nữa, dùng Hydroquinone thì tuân thủ nguyên tắc tuyệt đối nhé!

THỨ TỰ BÔI

Quy tắc 1: Lỏng trước, đặc sau. Mình thấy một bài viết phân biệt cách apply này cũng dễ hiểu nè. TEAM NƯỚC VÀ TEAM DẦU. Nước thì đi trước nhé.

Niacinamide: team NƯỚC

L-ascorbic acid: team NƯỚC

AHA/BHA: team NƯỚC / DẦU tùy kết cấu

Hydroquinone: team DẦU

Retinol: team DẦU

Vitamin E: team DẦU

Ceramides: team DẦU

Quy tắc 2: pH thấp trước, pH cao sau.

Niacinamide: pH 5.5-6.5

L-ascorbic acid: pH 2.5-3.5

AHA/BHA: pH 3-3.5

Hydroquinone: pH 5.5-7

Retinol: pH 6

THỜI GIAN CHỜ

Câu hỏi mang tính triệu đô trong dưỡng da “chờ 20-30p rồi bôi tiếp được không?” Thường lý do sợ khi kết hợp chung nãy giờ bạn đọc sẽ là sự chênh lệch pH và làm cho các hoạt chất mất tác dụng. Và người ta cho rằng tầm 30p sau thì da sẽ cân bằng pH trở lại. Thú vị khi bạn biết rằng một số nghiên cứu đã chỉ ra bạn cần nhiều hơn là 30p mà phải là 2 tiếng để da trở lại pH thường 5.5. Nghiêm túc mà nói, 30p đã là bất khả thi với mình, chờ 2 tiếng thì….trừ khi bạn chỉ ở nhà ăn ngủ và dưỡng da cả ngày nhé! Good luck!

Mà nói gì thì nói, cảm nhận cá nhân mình khi dùng, chờ tầm 5-10p da dịu lại hẳn, đỡ rát hay xót da hơn khi bạn dùng chung, nên đúng là có khác, chứ không phải không đâu nha!

TIPS TO TAKE AWAY

Nếu bạn thật sự muốn dập tơi tả mấy chất mạnh bạo này vào da:

BHA sáng + Vitamin C sáng / RETINOIDS tối + Niacinamide tối / AHA 1 lần 1 tuần (ngày đó không dùng bất cứ chất nào khác hoặc nếu có thể thì dùng Niacinamide tối đó thoải mái.

Thay Niacinamide bằng Hydroquinone nếu bạn muốn nhanh trắng (tuân thủ nguyên tắc dùng Hydroquinone)

Chúc các con nghiện dưỡng da sớm tìm được tình iu trọn đời của mình và nếu được hãy chia sẻ cho mình biết thêm trải nghiệm của bạn với các chất “kích thích” này nhé 😉

Mandelic-C Rejuvenating C-Serum

Mandelic acid and vitamin C are two popular skincare ingredients that work in tandem to improve skin texture, brighten the complexion, and combat signs of ageing. In this section, we’ll look at each ingredient in greater detail and investigate the benefits of using them together. Mandelic acid is a bitter almond-derived alpha-hydroxy acid (AHA). It has a larger molecular size than other AHAs such as glycolic and lactic acid, which allows it to penetrate the skin more slowly and cause less irritation. On the other hand, vitamin C is a strong antioxidant that shields the skin from environmental stressors and free radicals that can hasten the ageing process.

Do you put moisturiser after mandelic acid?

Yes, absolutely. In fact, applying moisturiser after mandelic acid will help counteract any potential dryness and irritation caused from the chemical exfoliation. You’ll also find that the moisturiser will form a physical barrier on the surface of the skin. This barrier enables the active ingredients that have already been applied to work undisturbed from exposure to free radicals, such as pollution. You’ll also find that a layer of moisturiser helps to lock hydration into the surface helping to keep the lipid barrier healthy and functioning properly.

GOOD TO KNOW…

  • Mandelic Acid can cause sensitivity to the sun so make sure you incorporate an SPF into your morning routine.
  • As an AHA, we recommend doing a patch test 24 hours before using in your routine to check your skin’s reaction.
  • When first using, build up the frequency of use in your routine to avoid over exfoliation which could damage the skin barrier.
  • Due to its regenerative properties, Mandelic Acid can also be used to target acne, even skin texture and reduce the appearance of fine lines.
  • Mandelic Acid is a great alternative if you experience irritation from Glycolic Acid Toner.
  • The Alpha Hydroxy Acid family are plant or animal derived ingredients which function to loosen the connection between surface skin cells to ‘exfoliate’ and allow them to shed. Their primary functions tend to focus on tone and texture for even and smooth looking skin.

What are AHAs?

Alpha hydroxy acids (AHAs) are chemical exfoliants that help the skin shed dead cells by loosening the “glue” that keeps these dead cells stuck to your face and body, allowing them to fall off naturally. Despite their chemical categorization, AHAs can actually be a gentler form of exfoliation than physical scrubs, which rip off dead cells on contact. There are many types of AHAs (glycolic, citric, mandelic, and lactic acids, to name four), but one thing they all have in common is that they’re water-soluble. As a result, they only work on the uppermost layer of skin.

What are the benefits of mandelic acid?

According to Nektalova, one of the great things about this non-irritating ingredient is its ability to “improve various skin concerns such as acne, hyperpigmentation and wrinkles, especially for those with sensitive skin.”

Also, this gentle ingredient can accelerate cell turnover, promote collagen production and exfoliate your skin while removing dead skin cells. “As a result of that, it improves the skin’s appearance [while reducing] the appearance of fine lines and wrinkles, dark marks and sun damage,” added Velez.

Alpha hydroxy acid (AHA) and vitamin C are two of the most well-known, highly regarded ingredients in skincare. Their beneficial effects have been exhaustively documented, and they can be used by almost every skin type under the sun. (Speaking of sun, AHAs and vitamin C are very good at reversing the appearance of too much sun exposure.) Obviously, you want both in your life. Read on to discover the best way to incorporate AHA and vitamin C into your skincare routine.

How to use mandelic acid

Mandelic acid can be paired with other popular skin care ingredients like hyaluronic acid, salicylic acid, vitamin C, glycerin, squalane, ceramides and other hydarators.

“Oftentimes, it’s found in chemical peeling agents that have multiple ingredients. [However], always seek out a board-certified dermatologist for professional-grade chemical peels if you are looking to try one!” added Velez.

Velez recommends implementing a small amount of mandelic acid to your evening skin care routine once a week after cleansing and before moisturizing to ensure skin tolerability. After, you can increase it from once to twice or three times a week in small concentrations.

“How often you use it depends on how your skin reacts,” mentioned Velez. “If you have reactions to it like redness, stinging or breakouts, cut back to every other day. Be aware that since it exfoliates the skin, it can increase sun sensitivity.”

If you’re going to be out in the sun, Nektalova advised pairing mandelic acid with at least a SPF 30 sunscreen.

“It works well with hydrating products like hyaluronic acid and should not be used together with retinoids,” she mentioned.

WHAT IS MANDELIC ACID?

Mandelic Acid is derived from bitter almonds and, whilst still potent, has a large molecule size making it suitable for sensitive skin as it penetrates the surface at a slower rate, causing less irritation. We’ve focused on this key ingredient because of its proven melanin inhibiting benefits to help reduce dark spots, hyperpigmentation & post acne marks. Alongside prevention, Mandelic Acid acts as an exfoliant, increasing cell turnover to even the skin tone.

In our lightweight formula, we’ve combined 10% Mandelic Acid; 0.1% Retinol and Glycerin to create a powerhouse combination that targets discoloration and dark spots by subtly exfoliating, encouraging natural cell turnover, whilst keeping the skin hydrated. 94% of people studied agreed the appearance of dark spots and hyperpigmentation were significantly reduced and skin tone appeared more even.

Acid layering combinations that pack a punch:

Azelaic Acid + Niacinamide:

Layering azelaic acid and niacinamide can improve skin congestion, inflammatory congestion, and fade post-acne marks for even the most sensitive skin. Azelaic acid is an anti-keratinizing agent that prevents the buildup of dead skin cells, which can cause congestion. It also reduces free fatty acid production, part of the pathogenesis of acne that also causes skin irritation. Due to its high molecular weight, azelaic acid is a more gentle exfoliant and actually reduces skin sensitivity, by reducing proinflammatory cytokines. Azelaic acid provides comedolytic and antimicrobial benefits, by addressing blemishes while minimizing impact on skin’s natural microflora.1 As a gentle exfoliant and tyrosinase inhibitor, it improves post-acne marks and scars. Like azelaic acid, niacinamide reduces fatty acid production and inhibits proinflammatory cytokines. It also reduces melanosome transfer, addressing a different mechanism in melanogenesis to further brighten the skin. When used together, azelaic acid and niacinamide can minimize and prevent skin congestion, reduce redness, and fade post-acne marks.

Polyhydroxy Acids + Retinol:

This duo can address photoaging and fine lines, working both within the skin and on the surface to smooth and firm. One clinical study noted significant skin smoothing and plumping benefits when combining PHA and the retinoid, retinyl acetate, while another study showed great skin tolerability of PHA and retinoic acid for treating acne.2 Retinol works from within, boosting collagen production, increasing epidermal and dermal thickness, improving skin elasticity, and speeding up cell renewal. Polyhydroxy acids have a large molecular weight and work on the surface of the skin, acting as humectants, antioxidants, and gentle exfoliants. Their antioxidant properties help prevent oxidative damage from UV exposure and fight glycation, sugar-induced sallowness and skin sagging. Polyhydroxy acids plump the skin and can offset the dryness caused by retinol while enhancing the therapeutic benefits of retinol. Pairing PHAs with retinol products puts you on the road to firmer, smoother, and more radiant skin.

Mandelic Acid + Vitamin C:

Pairing mandelic acid with vitamin C evens skin tone and improves skin texture and elasticity. The mechanisms of mandelic acid are not all known, but it strengthens and supports collagen production, inhibits tyrosinase to prevent hyperpigmentation, and has antibacterial and anti-inflammatory properties. Studies show that this acid is great for those with dry skin. With its large molecule weight, it more gently exfoliates for even skin texture. Like mandelic acid, vitamin C is a tyrosinase inhibitor and effectively brightens skin, fading age spots and uneven tone. It is also vital for collagen production, smoothing fine lines and wrinkles. Vitamin C is a potent antioxidant that fights oxidative damage from environmental stressors that lead to sagging, wrinkling, redness, inflammation, and pigmentation of skin. Layering mandelic acid with vitamin C can reduce discoloration, fine lines and wrinkles, and improve skin elasticity.

Tranexamic Acid + Alpha Arbutin:

Together tranexamic acid and alpha arbutin are the perfect team to address melasma, post-inflammatory hyperpigmentation, and overall brighten the skin. Tranexamic acid is less of an exfoliating acid and more of a skin brightener, acting as both a tyrosinase inhibitor and plasmin inhibitor. Throw in kojic acid to further address uneven skin tone and discoloration by chelating copper ions necessary for tyrosinase to function. Like tranexamic acid, alpha arbutin is a tyrosinase inhibitor, but it also slows melanosome maturation (the organelles that synthesize and store melanin or pigment). Alpha arbutin also addresses glycation, sugar-induced skin sallowness and loss of elasticity. Pairing tranexamic acid with alpha arbutin targets more than four different aspects of melanogenesis, fading the most stubborn discoloration caused by inflammation, acne, environmental stressors, melasma, and UV exposure.

Mandelic Acid + Salicylic Acid:

For the experienced skincare acid connoisseur, this treatment-intensive duo can address stubborn congestion and hyperpigmentation. A few studies explored this combination in the treatment of acne, post-acne scarring, and melasma.3,4 A combination of 20% salicylic acid + 10% mandelic acid (SM) outperformed 35% glycolic acid alone when treating these specific skin concerns. The combination SM was more effective and faster acting when improving acne, melasma, and post-inflammatory hyperpigmentation (PIH) in darker skin tones while also having better skin tolerability. Some research shows mandelic acid can increase sebum production, so pairing with salicylic acid may offset this, benefiting those with combination skin. Mandelic acid is a large AHA with slower penetration and exfoliation suited for sensitive skin while the lipophilicity of salicylic acid provides comedolytic and anti-inflammatory properties. Layering mandelic acid and salicylic acid can brighten skin and reduce skin congestion and inflammatory congestion, for all skin types.If you are new to acids and nervous about jumping in, there are a few ways to prevent irritation and over-exfoliation. Start by using an acid 2 times a week and work your way up to daily use, once you know that your skin can handle it. Select your acid based on the molecular size of the acid – the smaller the molecular size, the greater the penetration into the skin and the more potential for irritation. Cut back on physical exfoliants or face scrubs. Incorporate hydrating lipids, ceramides, and humectants in your routine to reduce dryness, flaking, or redness.Always remember to first patch test an acid, then slowly build up tolerance. Overexfoliation is counterproductive to your skin goals, resulting in erythema, overproduction of sebum, post-inflammatory hyperpigmentation, and irritated skin. There isn’t a right or wrong to layering: it’s about selecting products that address your skin concerns and learning what your skin can tolerate. Experiment and play, but also listen to your skin to find what works best for you.
