Niacinamide reduces hyperpigmentation by inhibiting melanosome transfer, improving skin tone and fading dark spots. It helps to even out discoloration for a more uniform complexion.
Niacinamide inhibits the transfer of melanosomes, which are pigment-containing vesicles, from melanocytes (pigment-producing cells) to keratinocytes (skin cells). This process reduces the amount of pigment deposited in the upper layers of the skin, leading to a reduction in hyperpigmentation, such as dark spots, age spots, and uneven skin tone. Regular application can improve overall skin tone and fade discoloration over time.
