Mô tả Mandelic Acid

Sơ lược về thành phần Mandelic Acid:

• Còn được biết đến với cái tên amygdalic acid
• Là một loại alpha hydroxy acid (AHA) có khả năng loại bỏ tế bào chết tối ưu
• Có thể sử dụng cho làn da nhạy cảm
• Cần được bảo quản trong bao bì mờ đục để tránh biến đổi

Chi tiết thành phần Mandelic Acid:

Mandelic Acid là một loại axit alpha hydroxy (AHA). Có một số nghiên cứu cho thấy axit mandelic là một chất tẩy tế bào chết hiệu quả, mặc dù nó không hiệu quả bằng Glycolic Acid do kích thước lớn gấp đôi Glycolic Acid và thâm nhập vào da chậm hơn. Tuy nhiên, những đặc điểm này cũng có thể làm cho Mandelic Acid dễ dung nạp hơn đối với những người có làn da nhạy cảm. Không giống như Glycolic Acid, Mandelic Acid nhạy cảm với ánh sáng và cần được đóng gói trong bao bì/lọ đựng mờ đục để duy trì hiệu quả.

Thành phần này có thể được tổng hợp trong phòng thí nghiệm hoặc chiết xuất từ hạnh nhân. Giống như các AHA khác, Mandelic Acid có hiệu quả nhất trong các sản phẩm với nồng độ pH từ 3-4.

Một vài nghiên cứu đã chỉ ra rằng Mandelic Acid và Salicylic Acid hoạt động hiệu quả với nhau trong một sản phẩm sử dụng cho mục đích làm mờ các đốm sắc tố, những vùng da không đều màu, bao gồm cả thâm mụn. Tuy nhiên, chúng tôi không chắc rằng thành phần Mandelic Acid khi sử dụng đơn lẻ thì có thể có những tác dụng gì bởi lợi ích đạt được có thể từ phía Salicylic Acid nhiều hơn.

Một vài nghiên cứu khác lại chỉ ra rằng Mandelic Acid có thể làm tăng tiết dầu, điều này không tốt cho da dầu nhưng lại có lợi cho da khô.

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.

Can You use Mandelic Acid with Vitamin C?

Everyone in one or another will benefit from a skincare routine that contains an AHA. Whether it’s a PHA, lactic acid or glycolic acid, you’ll be able to find one that is best suited to your skin type. When it comes to vitamin C, this is an ingredient that may need a little more time to introduce the active into your routine. Combing these powerhouses together could be something that super charges your results, or could it become a recipe for disaster?

This is exactly what we will be exploring in today’s blog post, before we get stuck into the nitty gritty, we’ll briefly run through what each of these ingredients do for the skin and the benefits you can expect to see.

What is mandelic acid?

• An acid that belongs to the group of chemical exfoliants called AHAs, also known as alpha hydroxy acid.
• Derived from bitter almonds and synthetically produced to be added into a skincare formula.
• Known for being one of the gentlest acids and can be used by those with a sensitive skin type.
• Effectively rids the skin of dead skin cell build-up, dirt, bacteria, debris, and other impurities.
• Reduces the appearance of fine lines and wrinkles due to the exfoliation bringing newer skin cells to the surface and skin firmer.
• Although it’s a gentle acid, it is also able to penetrate through the skin reaching the pores helping to unclog them of excess sebum, dirt, and other forms of bacteria.
• If you wanted to find out more about mandelic acid, check out our dedicated blog post.

What is vitamin C?

• Vitamin C, also known as L-ascrobic acid or ascorbic acid.
• Packed with antioxidants that can help protect the skin from overexposure to free radicals, such as pollution, UV rays, central heating, and other environmental aggressors.
• Combats areas of hyperpigmentation, dark spots, sun damage, and post acne scarring.
• Helps revive the complexion, restoring glow and luminous finish.
• Boost collagen production resulting in firmer skin, with a youthful bounce.
• Contains anti-inflammatory properties that help reduce the flare-up in skin redness and similar concerns.
• Find out more about vitamin C over on The Beauty Insiders.

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.

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.

Mandelic-C Rejuvenating C-Serum

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.

Tác dụng của Mandelic Acid trên da

3.Tẩy tế bào chết

Theo nguyên lý hoạt động của tế bào da, những tế bào đã chết có cơ chế tự động tách rời và rụng khỏi bề mặt da, tuy nhiên do tác động xấu của môi trường xung quanh như ánh sáng mặt trời, thói quen chăm da không đúng cách khiến da bị mất đi cơ chế tự nhiên đó. Để giải quyết vấn đề trên, nhóm AHA nói chung và Mandelic Acid nói riêng đã được ứng dụng vào các sản phẩm mỹ phẩm, hỗ trợ loại bỏ đi lớp tế bào sừng già giúp da dễ dàng tiếp nhận và tối ưu hiệu quả dưỡng chất được sử dụng.

3.Ngăn ngừa sự hình thành của mụn

Đối với làn da nhạy cảm, thường xuyên có mụn, Mandelic Acid còn có tác dụng kháng viêm, ngăn ngừa gia tăng mức độ viêm mụn, tình trạng tái phát mụn. Bên cạnh đó, kết hợp với việc có thể loại bỏ đi lớp da chết của Mandelic Acid, loại hoạt chất này còn ngăn ngừa hiệu quả sự hình thành của mụn từ nang lông do tăng tiết dầu nhờn hoặc bít tắc lỗ chân lông gây ra.

Tương tự như các hoạt chất AHAs khác, Mandelic Acid có tác dụng làm tăng sinh collagen, duy trì độ đàn hồi và săn chắc cho da, giúp da luôn tươi trẻ, đẩy lùi các dấu hiệu lão hóa như nếp nhăn, vết chân chim.

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.

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.

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.
