Niacinamide and rice extract revitalise and brighten the skin, significantly reducing pore size, smoothing skin texture, and reducing blackheads. Niacinamide's whitening and spot-reducing benefits: Niacinamide inhibits tyrosinase activity, preventing melanin formation, while accelerating the metabolism of melanin-containing keratinocytes and promoting melanin excretion, thereby achieving whitening and spot-reducing effects. It is an important ingredient in many whitening skincare products. Oil control and acne prevention: It regulates sebum secretion, reduces oil production, and maintains a balanced oil secretion level in the skin. For acne-prone skin, it reduces the occurrence of acne and improves the quality of acne-prone skin. Anti-Wrinkle and Anti-Ageing: It promotes collagen synthesis, increases skin elasticity and firmness, reduces the appearance of fine lines and wrinkles, and slows down the skin ageing process. Skin Barrier Repair: It increases the levels of free fatty acids and ceramides in the skin, enhances the skin's barrier function, helps the skin resist damage from external environments, and has a repairing and protective effect on sensitive and damaged skin.
