Reduces Hyperpigmentation

Niacinamide reduces hyperpigmentation by inhibiting melanosome transfer, leading to a more even skin tone with reduced dark spots and age spots. It prevents melanin from fully distributing to skin cells.

Niacinamide inhibits the transfer of melanosomes (pigment-containing vesicles) from melanocytes (pigment-producing cells) to keratinocytes (skin cells). This process reduces the appearance of hyperpigmentation by preventing melanin from being fully distributed to skin cells, resulting in diminished dark spots, age spots, and an overall more even skin tone.
