NIACINAMIDE

Also known as vitamin B3 and nicotinic acid, niacinamide is a very effective skin-restoring ingredient that offers multiple benefits for aging skin. Among these benefits is the ability to visibly improve the appearance of enlarged pores, uneven skin tone, fine lines, dullness, and a weakened skin surface. Niacinamide can also mitigate the damage environmental attack can cause, and is stable in the presence of heat and light.What about using vitamin C (ascorbic acid) and niacinamide in the same product or applied at the same time in separate products?ξYou might have read or heard that niacinamide and vitamin C shouldnŠ—Èt be used at the same time, whether found together in the same product or applied separately one after the other. Rest assured, this combination is fine and is in fact quite beneficial!ξThe research this misconception is based on was conducted in the 1960s; the forms of niacinamide and vitamin C used in this study were not stabilizedŠ—”although niacinamide itself is very stable. The base of the formula used in this study was also far different than todayŠ—Ès sophisticated skincare formulas. ξToday, cosmetic chemists know how to combine niacinamide and vitamin C in the ideal base formulas that enhance their compatibility.ξThe other common concern weŠ—Ève seen about combining these two ingredients has to do with the pH range. The concern is that the acidic environment ascorbic acid needs to be most effective will cause niacinamide will convert to nicotinic acid, a form that can be sensitizing, possibly inducing redness. Good news: This conversion process would only happen under conditions of the formula being exposed to very high heat for a long period of time. This would not apply to layering skincare products or to heat conditions that occur during manufacturing, transport, and storage of cosmetic products that contain niacinamide and ascorbic acid.

What all of this means is that you can use or layer products containing both niacinamide and vitamin C knowing that they will not render each other any less effective. Each of these ingredients on its own can help to address dark spots, uneven skin tone, wrinkles, loss of firmness, and dullness. When used together, they become even more of a powerhouse! This duo will help give you an even better chance at achieving a radiant, smooth, even, younger-looking complexion.References for this information:Journal of Agricultural Food and Chemistry, 2006, issue 7, pages 2558-2562Dermatological Surgery, 2005, issue 7 part 2, pages 860-865International Journal of Cosmetic Science, 2005, issue 3, pages 155-160Journal of Cosmetic Dermatology, 2004, issue 2, pages 88-93Journal of Investigative Dermatology, May 2017, page S116 International Journal of Pharmaceutics, March 2017, pages 158-162; and January 2013, Pages 192-201 Facial Plastic Surgery Clinics of North America, May 2016 , pages 145-152 Clinical, Cosmetic, and Investigational Dermatology, July 2015, pages 405-412 Skin Pharmacology and Physiology, June 2014, pages 311-315
