Dilute melanin, brighten and whiten Niacinamide can interfere with the cellular signaling channels between keratinocytes and melanocytes, thereby reducing the transfer of melanin to surface cells and reducing melanin precipitation, achieving a whitening effect. In addition, niacinamide also has anti glycation effects, which can lighten the dark waxy yellow face after protein glycation, thereby brightening the skin tone. 2. Anti aging, wrinkle removal The correct use of niacinamide can promote collagen synthesis, keeping the skin hydrated and elastic. An appropriate concentration of niacinamide can also have effective antioxidant effects, reducing wrinkles, pigmentation, etc. on aging facial skin. 3. Improve skin barrier function Topical application of niacinamide can increase free fatty acids and ceramides, stimulate microcirculation in the dermis, protect moisture in the skin from loss, prevent collagen loss in the dermis, repair the stratum corneum, prevent aging, and improve skin defense ability. 4. Moisturizing and oil controlling, reducing pores A certain concentration of niacinamide can exert effective moisturizing effects. Topical application of niacinamide can reduce the production of fatty acids and triglycerides in sebum, playing a role in controlling oil secretion. When oil secretion decreases, pores will not be enlarged, as it can achieve the effect of shrinking pores. 5. Prevention and treatment of pellagra, stomatitis, and glossitis. Package 20kg/drum,25kg/drum or requirement of clients.
