The main chromogenic substances in our skin include melanin, carotenoid and hemoglobin, among which melanin plays a very key role in our skin color and is influenced by its distribution and content in the skin and other decisive factors.
It is known that the amount of melanin in our body has nothing to do with our gender or race, but with our age. Melanin tends to decrease with age. Melanin is synthesized in the rough endoplasmic reticulum of melanocytes in the basal layer of our epidermis and transported to the Golgi apparatus, where it is packaged as a membrane to produce melanosomes. So what role does cosmetic grade nicotinamide play in the face of melanin?
As we all know, cosmetic grade nicotinamide has whitening effect, so it will have a certain impact on melanin, such as inhibiting the production of melanin, reducing the melanin already produced, so as to achieve the ideal whitening effect.
