The ordinary niacinamide worked brilliantly for me. That would be a bit too harsh. 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. ‘Postinflammatory hyperpigmentation: a review of the epidemiology, clinical features, and treatment options in skin of color’.

(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.) In fact, a number of different skincare ingredients compliment and enhance the effects of others. If your makes your skin itchy, don’t use it all. 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 . ‘Preliminary open-label clinical evaluation of the soothing and reepithelialisation properties of a novel topical formulation for rosacea’. ‘Topical retinaldehyde with glycolic acid: study of tolerance and acceptability in association with anti-acne treatments in 1,709 patients’. 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. 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!
