@ahkeng1965: #drleo #drleomy #drleoacneessence #creatorsearchinsight #whiteningcream -- Why Niacinamide and Vitamin C Are the Right Choice for Brighter Skin Niacinamide and Vitamin C work together through different but complementary mechanisms, making them a powerful duo for skin brightening. How They Work Vitamin C acts as a "production stopper." It is a strong antioxidant that inhibits the enzyme tyrosinase, which is responsible for producing melanin. By blocking this enzyme, Vitamin C reduces the amount of pigment your skin cells actually create. Niacinamide, on the other hand, acts as a "transfer blocker." It does not stop melanin production. Instead, it works at the next stage by preventing melanosomes (pigment packages) from moving from pigment-producing cells to the skin's surface. In short, even if melanin is still produced, Niacinamide ensures it never reaches the upper layer of your skin to be seen. One clinical study found it provides 35–68% inhibition of this transfer process. Scientific Evidence Modern research supports this synergy. A 2022 study confirmed that the combination reduces oxidative stress and melanogenesis signals. A 2025 in-vitro study showed that a formula containing 5% Niacinamide was superior to 10% Vitamin C alone in reducing melanin levels after UV exposure
