The content and distribution of melanin have a great impact on skin color. The more melanin, the darker the skin color. However, nicotinamide can inhibit the production of melanin and activate cyclic 3,5 nucleotide phosphodiesterase, an enzyme that can stimulate the decomposition of 3,5-cyclic adenylate in melanocytic hormones, Thereby inhibiting melanin production. Nicotinamide can not only inhibit the production of melanin but also reduce the melanin already produced.
