Yes, niacinamide effectively helps reduce hyperpigmentation. Multiple studies and reputable sources confirm its efficacy in lightening skin and diminishing the appearance of dark spots.
How Niacinamide Works on Hyperpigmentation
Niacinamide works by inhibiting the transfer of melanosomes (pigment-containing organelles) from melanocytes (pigment-producing cells) to keratinocytes (skin cells). This process significantly reduces the amount of melanin reaching the skin's surface, leading to a lighter complexion and diminished hyperpigmentation.
