Niacinamide provides a wide range of effects. It effectively works against redness of the skin, it relieves hyperpigmentation, it reduces excessive sebum production, it works against pimples, promotes the synthesis of collagen and ceramides in the skin and thus effectively prevents wrinkles and supports the regeneration of the skin. Likewise, the transepidermal water loss of the skin is reduced, which has a positive effect on the moisture content of the skin. An all-rounder that is difficult to dispense with in skin care.
