For example, a combination of retinaldehyde and glycolic acid demonstrated a good tolerability and significant improvement in acne lesions after 1-3 months of use [58]. I recommend you put on benzoyl peroxide in the morning and use salicylic acid and retinoids at night. Visit our online shop: https://shop.beautywithinofficial.com/ Hi guys! Alternatively, the new active might have been the tipping point, pushing your skin into a state of irritation. What Does pH Balanced Mean? ‘Topical vitamin C and the skin: mechanisms of action and clinical applications’. (2005). Tfayli, A., Jamal, D., Vyumvuhore, R., Manfait, M. & Baillet-Guffroy, A. After reading your article which i enjoyed. This is a great example of how a number of ingredients that when combined together, in theory, should be highly irritating to the skin. ‘The effect of glycolic acid on the treatment of acne in Asian skin’. For example, in a study that incubated human skin for 48 hours with centella asiatica, vitamin A, vitamin E, vitamin C, and their combinations, each ingredient, alone, increased the production of collagen two-fold (2x). When i googled ethyl ascorbic acid ph level it said 4.0-5.0 so i just dont understand why i cant use ethyl ascorbic acid and buffet together. The fact that I no longer had an easy skin type was both a physical and a mental problem for me and it inspired me even more to read into skin care and get to the bottom of the problem. Yet another example of more is more in skincare! Lowe, N. (2006). Follow all instructions closely. I am planning on writing a full blogpost on skin care acids, so stay tuned if you want to know more about that. This basically means that niacinamide prevents pigment leaking into other surrounding cells. ‘Chapter 10: Niacinamide: A topical vitamin with wide-ranging skin appearance benefits’. This suggests that the combination of zinc oxide and iron oxide in sunscreen is particularly beneficial for individuals with melasma. Visible light, especially high energy visible (HEV) light, represents about 39-44% of total solar radiation and enters the skin in the same way that UV radiation does [38]. In addition, AHAs increase the rate of skin cell turnover which helps bring skin pigment to the surface of the skin faster where it can be shed as part of normal epidermal desquamation (skin shedding) [46]. Notify me of follow-up comments by email. While all patients experienced reductions in hyperpigmentation, those who used the iron oxide sunscreen experiences significantly greater improvements [42]. Do not take salicylic acid (psoriasis or seborrheic dermatitis) by mouth. This is because both vitamin C and glycolic acid are known to boost collagen levels in the skin and it appears that their effects may be additive. Ceramides account for about 45-50% of this mixture, cholesterol for approximately 25%, and free fatty acids for around 10-15%, When this lipid matrix is depleted, skin can become dehydrated. When used together, start by applying hyaluronic acid then followed by niacinamide. ‘Efficacy and safety of 0.1% retinaldehyde/ 6% glycolic acid (Diacneal) for mild to moderate acne vulgaris’. Salicylic acid or benzoyl peroxide must be absorbed by the skin to be effective. Mukherjee, S., Date, A., Patravale, V. et al. Both ingredients target both of these causes and research has found that topical combinations of salicylic acid and niacinamide can significantly reduce surface sebum levels and pore size after 12 weeks of use [2]. ‘Irradiation of skin with visible light induced reactive oxygen species and matrix degrading enzymes’. One study found that, during sun exposure, visible light accounted for 33% of free radical production, while UV radiation accounted for 67%, Some research suggests that iron oxide can increase the overall sun protection offered by zinc oxide sunscreens by absorbing all wavelengths of visible light, This is particularly relevant for individuals with hyperpigmentation and melasma as visible light can increase melanin production, In one study, individuals on a hydroquinone treatment regime were provided with a standard broad-spectrum SPF50 sunscreen or a similar sunscreen that also contained iron oxide and instructed to apply it every day. Caffeine has also demonstrated antioxidant and photoprotective effects and offers additional UV radiation and free radical protection when added to sunscreens [22]. 82, 1123– 1131. ‘The extracellular matrix of stratum corneum: role of lipids in normal and pathological function’. For this reason, topical application of vitamin C is required to maintain sufficient skin levels of vitamin C, Vitamin E is the most important lipid-soluble antioxidant in tissue and is particularly abundant in the outermost layer of the skin (the stratum corneum) where it is delivered by sebum. Resveratrol + Glycolic Acid = Reduced Hyperpigmentation. ‘Near visible light and UV photoprotection in the treatment of melasma: a double-blind randomized trial’. 5 Of The Best Hydrating Products For Acne Prone Skin. ‘Sunscreens inadequately protect against ultraviolet-A-induced free radicals in skin: implications for skin aging and melanoma?’. Chamlin, S., Kao, J., Frieden, I. et al. I prefer using these in the evening, as the formula of both doesn’t do very well under makeup. However, initially, retinol can cause irritation and dryness of the skin by damaging the skins barrier and increasing transepidermal water loss (TEWL) [50]. ‘The effect of Centella asiatica, vitamins, glycolic acid and their mixtures preparations in stimulating collagen and fibronectin synthesis in cultured human skin fibroblast’. Same as AM but without SPF Niacinamide can help decrease retinol irritation, and on top of that, the added barrier function benefit definitely is a plus! Similar levels of free radical protection are also offered when antioxidants are used alone [15]. ‘Preliminary open-label clinical evaluation of the soothing and reepithelialisation properties of a novel topical formulation for rosacea’. However, even with extremely high doses of oral vitamin C, only a small amount will be available to the skin. The combination of the two completely got rid of my under-skin bumps and any other spots, The Niacinamide helps to balance my skin’s oil-production without completely stripping it, They work really quickly, you get visible results after just one or two uses, They’re so cheap (only around 10 euros each! That’s right, there truly are some skincare ingredient power couples! While some skincare ingredients work against each other or irritate skin when combined, others can enhance each others effects. ‘After 30 years…the future of hydroxyacids’. Kaye, E., Levin, J., Blank, I. et al. Photobiol. ‘Caffeine’s mechanisms of action and its cosmetic use’. Farage, M., Miller, K., Elsner, P. & Maibach, H. (2008). Salicylic acid has relatively natural origins, as it was once derived from the metabolism of salacin, often found in the bark of willow trees. Recently, a hybrid of glycolic acid and resveratrol, resveratryl triglycolate, has demonstrated the ability to reduce sun induced pigmentation when applied twice daily for 6-8 weeks [48]. In fact, one study found that a topical cream containing ceramides, cholesterol, and fatty acids improved skin hydration within 30 minutes of application [31]. Some research suggests that caffeine enhances the antioxidant effects of green tea polyphenols and that both together may help prevent free radical production and UVB-induced skin cancer [23]. These two definitely address a certain skin type: the Niacinamide + Zinc is your best friend if you suffer from oily skin, and combined with the the Salicylic Acid it’s perfect to treat blemish- and acne-prone skin. Other ingredient combinations to check out: Have you found any skincare ingredient combinations that work particularly well? ‘Reduction in the appearance of facial hyperpigmentation by topical N-acetyl glucosamine’. Because NAG and niacinamide target pigmentation in two separate ways (NAG prevents melanin production while niacinamide prevents the spread of existing melanin), they are highly likely to compliment each other when used together. One study found that a topical combination of vitamin C and a centella asiatica extract significantly improved skin suppleness, firmness, and hydration, as well as improving the appearance of wrinkles, after 6 weeks of use [36]. This is because both vitamin C and glycolic acid are known to boost collagen levels in the skin and it appears that their effects may be additive. I was so confused. Haywood, R., Wardman, P., Sanders, R. & Linge, C. (2003). Because they both tackle the same issues and I feel like they work best when teamed up, I decided to combine the two products into one review. Niacinamide and salicylic acid work together to calm and minimize breakouts, while licorice root extract and vitamin C help the niacinamide brighten hyperpigmentation and acne scars. ‘Clinical, biometric and structural evaluation of the long-term effects of a topical treatment with ascorbic acid and madecassoside in photoaged human skin’. Frankly, I have never suffered from severe acne, but based on … ‘Nicotinic acid/niacinamide’. Keep out of your mouth, nose, and eyes (may burn). Usuki, A., Ohashi, A., Sato, H., Ochiai, Y., Ichihashi, M. & Funasaka, Y. AHAs, such as glycolic and lactic acid, act as chemical exfoliants and help remove dead skin cells and loosen the top layer of skin. Deciem Responses Regarding Conflicts & The Ordinary Products You Can & Cannot Mix Why can´t I now use Vitamin C derivatives with Niacinamide? Song, X., Xu, A., Pan, W. et al. (2008). ‘New insights in photoaging, UVA induced damage and skin types’. Some research suggests that iron oxide can increase the overall sun protection offered by zinc oxide sunscreens by absorbing all wavelengths of visible light [40]. Another great antioxidant pairing is green tea and caffeine. Bonus tips: Drink lots of water. Use on your skin only. If you’ve ever wondered whether you can incorporate niacinamide and acid in one skincare routine, rest assured—you definitely can! Products That Combine Centella Asiatica & Vitamin C: Products That Combine Centella Asiatica & Vitamin C & Glycolic Acid: As mentioned earlier, sunscreen is very very important for preventing aging and improving overall skin health. & Brody, N. (2011). (This happened to me, when I went from Biologique Recherche Lotion P50, which contains lactic acid, to COSRX BHA Blackhead Power Liquid, which contains salicylic acid—a much stronger acid.) The addition of, Like UV radiation, visible light can also lead to the production of free radicals. Considering the price, it is probably best to save this product just for the dark spots that rea Because of its ability to reduce inflammation, decongest pores and assist with exfoliation, it is commonly used to treat acne," McBride explains. In some instances, this may lead to increased skin irritation, but this is not always the case. Glycolic Acid + Vitamin C = Increased Collagen and Skin Thickness, Reduced Hyperpigmentation. As you can imagine, the two combined may be quite irritating for skin. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3047947/, https://onlinelibrary.wiley.com/doi/pdf/10.1002/9781118384824.ch10, https://www.ncbi.nlm.nih.gov/pubmed/17134422, https://doi.org/10.1111/j.1524-4725.2005.31732, https://www.ncbi.nlm.nih.gov/pubmed/952756/, https://www.ncbi.nlm.nih.gov/pubmed/24641601/, https://www.ncbi.nlm.nih.gov/pubmed/23732711, https://www.ncbi.nlm.nih.gov/pubmed/18377617, https://www.researchgate.net/publication/256618684_Free_Radicals_In_Biology_And_Medicine, https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1751-1097.1989.tb05548.x, https://www.ncbi.nlm.nih.gov/pubmed/14632206, https://www.ncbi.nlm.nih.gov/pubmed/17205635, https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1529-8019.2012.01505.x, https://www.sciencedirect.com/science/article/pii/S0022202X15358292, https://www.sciencedirect.com/science/article/pii/S0738081X09001254, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5605218/#B3, https://www.ncbi.nlm.nih.gov/pubmed/18045356/, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3673383/, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4976416/, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2958188/, https://www.ncbi.nlm.nih.gov/pubmed/23075568, https://europepmc.org/abstract/med/21720657, https://www.jaad.org/article/S0190-9622(17)31504-9/fulltext, https://www.ncbi.nlm.nih.gov/pubmed/23951566, https://pubs.acs.org/doi/abs/10.1021/bi00382a045?journalCode=bichaw, https://core.ac.uk/download/pdf/82665629.pdf, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4216025/, https://www.jaad.org/article/S0190-9622(02)00048-8/fulltext, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3116297/, https://www.ncbi.nlm.nih.gov/pubmed/9731470/, https://www.researchgate.net/profile/Puziah_Hashim4/publication/260431233_The_effect_of_Centella_asiatica_vitamins_glycolic_acid_and_their_mixtures_preparations_in_stimulating_collagen_and_fibronectin_synthesis_in_cultured_human_skin_fibroblast/links/564aaf6208ae44e7a28dd030.pdf, https://www.ncbi.nlm.nih.gov/pubmed/18503551/, https://www.ncbi.nlm.nih.gov/pubmed/16311163, https://jamanetwork.com/journals/jamadermatology/article-abstract/552806, https://www.ncbi.nlm.nih.gov/pubmed/18248499, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3936427/, https://www.ncbi.nlm.nih.gov/pubmed/21348540?dopt=Abstract, https://www.ncbi.nlm.nih.gov/pubmed/14756523/, https://www.sciencedirect.com/science/article/pii/S0923181104000982, https://link.springer.com/article/10.1007/s00403-016-1644-9, https://www.ncbi.nlm.nih.gov/pubmed/29663438, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2699641/, https://www.spandidos-publications.com/ijmm/22/2/229, https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1473-2130.2004.00115, https://www.ncbi.nlm.nih.gov/pubmed/8543691/, https://www.tandfonline.com/doi/abs/10.3109/14764172.2012.748199, https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1524-4725.1998.tb04262.x, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3840548/, https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1524-4725.1997.tb00003.x, https://www.karger.com/Article/Abstract/81498, https://www.karger.com/Article/Abstract/81500, https://www.ncbi.nlm.nih.gov/pubmed/17348991, https://www.ncbi.nlm.nih.gov/pubmed/20725554?dopt=Abstract, https://www.ncbi.nlm.nih.gov/pubmed/12100180, https://www.ncbi.nlm.nih.gov/pubmed/19845667/. So will ingredient X counteract our ingredient Y? “However, like aspirin, salicylic acid also has anti-inflammatory properties which can calm the skin and minimize irritation.” Many labels for acid-based products display the percentage of acid used (i.e., 2 percent salicylic acid), informing consumers of a product’s supposed strength. Let us know in the comments section! Less spots, slightly mire refined pores, over all improved texture. Using niacinamide and salicylic acid together. Jagdeo, J. Niacinamide, which is also called nicotinamide, is one of two major forms of vitamin B3 (niacin) found in supplements (the other is nicotinic acid). Yes, you can pair both of these ingredients together. There’s no third wheel here! Kameyama, K., Sakai, C., Kondoh, S. et al. Iron oxide is not an approved sunscreen but is often added to mineral sunscreens to reduce white cast. Ezra, if you have oily, acne-prone skin stop using a AHA exfoliator and switch to salicylic acid. Products That Combine Retinol & Niacinamide: Although the combination of glycolic acid and vitamin C may not be suitable for all skin types, they make a powerful pairing. (2013). Layering and mixing skincare ingredients can be overwhelming at the best of times. ‘Intrinsic and extrinsic factors in skin ageing: a review’. ‘Epidermal desquamation’. (2005). Niacinamide & Salicylic Acid Niacinamide, a water soluble form of vitamin B3, and salicylic acid, a beta-hydroxy acid, work particularly well when combined together. Research suggests that niacinamide can decrease the transfer of melanosomes from melanocytes to keratinocytes by up to 68% and interferes with the cell signalling pathways between keratinocytes and melanocytes [63]. Related Reading: Does Niacinamide Cause Purging? ‘Studies on the effect of salicylic acid on normal skin’. Niacinamide & Retinol Together = A Perfect Pair! Should I keep using them at the same time, and if so, in what order? Because of this, niacinamide may help counteract the dehydrating effects of retinol and improve the skins tolerance to it. In fact, a large randomized controlled study found that the combination of niacinamide and NAG worked really well at reducing pigmentation. I also wanted to add in a bha product, so I purchased Paula's Choice 1% salicylic acid liquid exfoliant. Will they interact and leave us with irritated and painful skin? Today, I finally feel as if I have it under control thanks to lots of patience, a dietary turnover and these two products by The Ordinary: the Niacinamide 10% + Zinc 1% and the Salicylic Acid 2% Solution. Ceramides account for about 45-50% of this mixture, cholesterol for approximately 25%, and free fatty acids for around 10-15% [25]. Ash, K., Lord, J., Zukowskl, M. & McDaniel, D. (2013). In addition, vitamin C is one of the few examples in life where three is not a crowd. ‘Postinflammatory hyperpigmentation: a review of the epidemiology, clinical features, and treatment options in skin of color’. Enlarged pores are caused by two main factors; increased sebum levels and reduced levels of collagen and elasticity in the skin. Vitamin C and vitamin E are possibly the best example of a skincare power couple as they each enhance the effects of the other. Antioxidants are molecules that naturally co-exist in our skin to protect it from free radical damage. & De Ponti, I. Can You Use Vitamin C and Retinol Together? Zinc Oxide + Iron Oxide = Increased Photoprotection, Reduced Hyperpigmentation. In fact, with some formulations it does appear that more is more! However, these ingredients can be found in OTC moisturizers and, when applied to the skin, replenish the substances that the stratum corneum is lacking, thus improving skin hydration [28]. ‘Nicotinamide increases biosynthesis of ceramides as well as other stratum corneum lipids to improve the epidermal permeability barrier’. Loden, M. (2016). However, in certain formulas, the combination of glycolic acid and retinol can be well-tolerated and a complimentary and effective acne treatment. ‘Inhibitory effect of magnesium L-ascorbyl-2-phosphate (VC-PMG) on melanogenesis in vitro and in vivo’. It’s important to wash your face firstly with oil based cleanser and then use your regular face wash (salicylic acid) Use toner before serum having niacinamide: I personally recommend to use toner before using niacinamide because it will prepare your skin for better absorption of another skin care products. This skin damage occurs when free radicals produced by UV radiation alter cellular DNA and break down the collagen in the skin [9][10]. Hashim, P. (2014). Liebel, F., Kaur, S., Ruvolo, E., Kollias, N. & Southall, M. (2012). Or maybe, just maybe, will they enhance each other and let us experience the glowing skin that we have only ever dreamed of? Furthermore, the retinaldehyde and glycolic acid formulation can enhance the effects of these other acne treatments [60]. Unfortunately, sunscreen is only able to block about 55% of the free radicals produced by UV exposure [12] and, alone, provides no protection from the free radicals produced by either infrared radiation or visible light [13]. In addition, free radicals are also produced by other forms of solar radiation, including visible light and infrared radiation. Basically, the addition of vitamins A, C, and E with centella asiatica didn’t increase the production of collagen anymore than when vitamin C was added to centella asiatica on its own. & Berge, C. (2006). Niacinamide offers similar benefits [4], as well as reducing redness and pigmentation and improving skin barrier function [2]. Combining niacinimadie’s oil-reducing prowess with salicylic acid’s ability to dissolve excess oil is a great way to help keep pores clear and breakouts at bay. ‘An overview of ultraviolet radiation, sunscreens, and photo-induced dermatoses’, Haywood, R. (2006) Relevance of sunscreen application method, visible light and sunlight intensity to free-radical protection: A study of ex vivo human skin. Products That Combine Vitamin C & Vitamin E & Ferulic Acid: Another great antioxidant pairing is green tea and caffeine. It contains 2% of salicylic acid that works effectively on my skin. Frederick, J., Snell, H. & Haywood, E. (1989) ‘Solar ultraviolet radiation at the earth’s surface’. This is particularly the case when it comes to reducing pore size. ‘Treatments Improving Skin Barrier Function’. Both ingredients target both of these causes and research has found that topical combinations of salicylic acid and niacinamide can significantly reduce surface sebum levels and pore size after 12 weeks of use, InstaNatural Age Defying Skin Clearing Moisturizer, This is because roughly 80-90% of all facial skin aging is caused by sun damage, This skin damage occurs when free radicals produced by UV radiation alter cellular DNA and break down the collagen in the skin, In addition, free radicals are also produced by other forms of solar radiation, including visible light and infrared radiation. ‘Pharmacological review on centella asiatica: A potential herbal cure-all’. Niacinamide is able to stabilise the skins barrier function by reducing the amount of water lost and improving hydration [51]. Some evidence suggest that this is due to its ability to increase the levels of ceramides, free fatty acids, and cholesterol in the stratum corneum [52]. But, there’s a catch. Like UV radiation, visible light can also lead to the production of free radicals. They basically ‘mop-up’ the damage done by UV radiation and other environmental aging factors (smoking, pollution, etc.) Berson, D., Osborne, R., Oblong, J., Hakozaki, T., Jonson, M. & Bissett, D. (2014). Products That Combine Glycolic Acid & Resveratrol: Retinol is a derivative of vitamin A that can increase the rate of skin cell turnover and renewal, reduce sun damage, boost collagen production, improve the appearance of wrinkles, reduce pigmentation, and increase skin hydration [49]. Specifically, a mix of 0.5% ferulic acid and 1% vitamin E with 15% vitamin C increases the effects of vitamin C eight-fold (8x) [19]. This basically means that niacinamide prevents pigment leaking into other surrounding cells. Available at: Oresajo, C., Pillai, S., Manco, M., Yatskayer, M. & McDaniel D. (2012). Park, S., Seok, J., Kwak, J. et al. If you’re looking for some hormonal breakout warriors, read on! (2007). Hello! You can find The Ordinary in Belgium on ASOS or the British website Cult Beauty (but they’re very often sold out!). However, NAG can be unstable when used alone [62]. The Ordinary! Lol. Barbara. Golden, G., Guzek, D., Kennedy, A., McKie, J. This suggests that application of niacinamide is able to prevent the typical irritant effects often experienced upon commencing retinol treatment. Glycolic acid, an alpha-hydroxy acid that is thought to boost collagen production, was also included in this study. These effects are largely down to the polyphenols (antioxidant molecules) that are naturally present in green tea. (2013). Use salicylic acid (psoriasis or seborrheic dermatitis) as ordered by your doctor. One study found that a topical combination of vitamin C and a centella asiatica extract significantly improved skin suppleness, firmness, and hydration, as well as improving the appearance of wrinkles, after 6 weeks of use, Glycolic acid, an alpha-hydroxy acid that is thought to boost collagen production, was also included in this study. Herman, A. Vitamin E is the most important lipid-soluble antioxidant in tissue and is particularly abundant in the outermost layer of the skin (the stratum corneum) where it is delivered by sebum. (1996). Green Tea + Caffeine = Increased Protection Against UVB-induced Skin Cancer. If your makes your skin itchy, don’t use it all. (2018). With its offer of retinoids, direct acids, oils and more straightforward products, The Ordinary is known to be a very humble and no-nonsense brand. Another great skincare ingredient combination for hyperpigmentation and melasma is glycolic acid and resveratrol. Both have anti-aging and anti-acne effects and offer some level of UV protection. Haftek, M. Mac-Mary, S., Le Bitoux, M. et al. Burke, K. (2007). Exfoliation or Masking (Optional) This is a completely optional step (skip to number 3 or 4 if don’t … AHAs, such as glycolic and lactic acid, act as chemical exfoliants and help remove dead skin cells and loosen the top layer of skin. The name's pretty new too me. From left to right: Niacinamide +Zinc, High Spreadability Fluid Primer, Salicylic Acid 2%, Buffet, Azelaic Acid Suspension 10% Now the first one I'm gonna discuss is the Azelaic Acid. Mao-Qiang, M., Feingold, K., Thornfeldt, C. & Elias, P. (1996). The major polyphenol present in green tea is epigallocatechin-3-gallate (EGCG) that has also been shown to have sunscreen properties [21]. Like salacin, salicylic acid is an anti-inflammatory substance with chemical similarities to aspirin. For example, vitamin C helps to regenerate vitamin E, making it more readily available to protect the skin from free radicals. Specifically, 4% niacinamide combined with 2% NAG was significantly more effective at reducing pigmentation than a vehicle control formulation, Furthermore, niacinamide appears to have an additive effect when combined with NAG. Salicylic Acid + Niacinamide "Salicylic Acid is a pore-cleansing Beta Hydroxy Acid (BHA). When added to sunscreen, antioxidants are able to reduce the production of free radicals by up to 78%. Callender, V., St Surin-Lord, S., Davis, E. et al. A number of in vitro and in vivo studies have demonstrated that these lipids, particularly ceramides play a vital role in skin hydration by regulating the amount of water in and out of the skin [26][27]. Great for acne breakouts, salicylic acid shrinks them up, and fast. that is known to reduce pigmentation and inflammation and has anti-aging properties, It inhibits tyrosinase, the key enzyme in the production of melanin, in various ways and thus prevents the conversion of DOPA to melanin, Some research suggests that glycolic acid, as well as other AHAs, also inhibit tyrosinase, In addition, AHAs increase the rate of skin cell turnover which helps bring skin pigment to the surface of the skin faster where it can be shed as part of normal epidermal desquamation (skin shedding), In addition, glycolic acid is very good at penetrating skin, Recently, a hybrid of glycolic acid and resveratrol, resveratryl triglycolate, has demonstrated the ability to reduce sun induced pigmentation when applied twice daily for 6-8 weeks, When investigated separately, this combination of resveratrol and glycolic acid inhibited tyrosinase more effectively than glycolic acid alone. Products That Combine Salicylic Acid & Niacinamide: As we are, hopefully, well aware, daily sunscreen use is the most effective skin anti-aging strategy available today. ‘Retinoids in the treatment of skin aging: an overview of clinical efficacy and safety’. Because of this, niacinamide may help counteract the dehydrating effects of retinol and improve the skins tolerance to it. Man, M., Feingold, K. & Elias, P. (1993). Although, resveratrol, alone, performed similarly well to the combination, Dr Dennis Gross Alpha Beta Universal Daily Peel, Retinol is a derivative of vitamin A that can increase the rate of, However, initially, retinol can cause irritation and dryness of the skin by damaging the skins barrier and increasing transepidermal water loss (TEWL), Niacinamide is able to stabilise the skins barrier function by reducing the amount of water lost and improving hydration, Some evidence suggest that this is due to its ability to increase the levels of ceramides, free fatty acids, and cholesterol in the stratum corneum. Vitamin C and glycolic acid are also useful for treating hyperpigmentation as both are effective at inhibiting tyrosinase and decreasing melanin production, When used together, vitamin C and glycolic acid demonstrated an ability to significantly improve hyperpigmentation, as well as reduce pore size and improve, Other research has found that glycolic acid and vitamin C combinations are particularly good at treating stretch marks by increasing epidermal and papillary dermal thickness, This further highlights an anti-aging benefit of vitamin C and glycolic acid combinations as epidermal and papillary dermal thicknesses both decrease with age leading skin to become more transparent, Another skincare ingredient combination that is often shunned due to its irritation potential is that of retinol and alpha-hydroxy acids (AHAs). Related Reading: Niacinamide & Retinol Together = A Perfect Pair! Niacinamide (Vitamin B3) reduces visible congestion and blemishes, zinc balances the production of sebum (your skin’s oil). Niacinamide and Hyaluronic Acid Together = Super Skin Hydration. ‘Interaction of vitamins C and E as better cosmeceuticals’. It’s how they keep the price so low, but it also counteracts with makeup and sometimes with other products. (2008). Zinc oxide is a mineral (physical/inorganic) sunscreen, which means that it protects the skin from UVA and UVB radiation by reflecting and scattering light. Vitamin C is the most abundant antioxidant in the skin and is essential for the production of collagen [16]. ‘Human skin-depigmenting effects of resveratryl triglycolate, a hybrid compound of resveratrol and glycolic acid’. Laura is currently working in healthcare education and writes for ScienceBecomesHer in her spare time. Gycolic toner, pure L Absorbic Acid powder mix with a snail mucin and a Vit C serum (Andalou) with a Vit C E Ferulic oil?? Thanks so much!! My other concern is can i use more of the same product in a skin care routine. Products That Combine N-Acetyl Glucosamine & Niacinamide: We have discussed 12 examples of skincare ingredient combinations where less is not more. Per those acne-fighting benefits, niacinamide is often paired with salicylic acid, a beta-hydroxy acid that’s a mainstay in acne products, says Dr. Frieling. The Ordinary Salicylic Acid 2% Solution is a direct acid. N-Acetyl Glucosamine (NAG) is an amino sugar and precursor to hyaluronic acid that inhibits tyrosinase glycosylation, thus reducing melanin production [61]. Retinol + Niacinamide = Increased Tolerability Of Retinol. This is particularly relevant for individuals with hyperpigmentation and melasma as visible light can increase melanin production [41]. Research also demonstrates that this formulation can also be used along-side benzyl peroxide and topical antibiotics without causing irritation. I’m using the salicylic acid cleanser from The Inkey List. As you can see, niacinamide and salicylic acid offer similar benefits but work in slightly different ways.
