6 skin care effects of niacinamide
Niacinamide can down-regulate melanin transport from melanocytes to keratinocytes without inhibiting tyrosinase activity or cell proliferation, thereby affecting skin pigmentation, and it can interfere with keratinocytes and melanocytes. Intercellular signaling pathways that reduce melanogenesis. Niacinamide, on the other hand, acts on the already produced melanin, reducing its transfer to the superficial cells.
Studies have shown that the use of nicotinamide (5%) can reduce wrinkles, erythema, yellowing and pigmentation on aging facial skin. So you don’t have to wonder that Olay’s anti-aging line contains a lot of nicotinamide. These effects may also be related to the ability of nicotinamide to stimulate collagen production.
3. Improve skin barrier function
Topical topical nicotinamide can increase the level of free fatty acids and ceramides in the skin, stimulate microcirculation of the dermis and prevent skin moisture loss. It also enhances protein synthesis (such as keratin), increases intracellular NADPH levels, and accelerates keratinocyte differentiation. In addition, it can alleviate skin irritation caused by surfactants or solvents.
The above-mentioned ability to improve the skin barrier function means that nicotinamide has moisturizing ability. A small study shows that topical 2% nicotinamide is more effective than petrolatum (petroleum) in reducing skin loss and increasing moisturization.
5. Control oil and reduce pores
Topical nicotinamide (2%) can reduce the production of fatty acids and triglycerides in sebum, and has the effect of controlling oil secretion. It is said to have a synergistic effect with sodium dehydroacetate. The reduction in oil secretion will also make the skin pores look less large.
6. Treatment of acne
It is reported that a gel containing 4% nicotinamide is effective in treating acne vulgaris with 1% clindamycin gel (a major topical topical drug for the treatment of acne).
