Niacin is also known as vitamin B3, its metabolite is nicotinamide, therefore, nicotinamide is also a derivative of vitamin B3. Nicotinamide is widely used in all kinds of skin care and cosmetic products. As early as the 1970s, some people added nicotinamide and sunscreen in the cream system, the main purpose is to whiten the skin.
Currently, cosmetic grade nicotinamide is mainly used in skin care products, which can reduce the production of melanin. It is through the stimulation of cyclic 3, 5-nucleotide phosphodiesterase to promote the decomposition of 3, 5-cyclic adenosine acid, and obtain adenine-5-monophosphate.
Cosmetic grade nicotinamide is a small molecule that can be directly absorbed by cells to balance skin energy, restore cell energy, accelerate collagen synthesis, promote the exfoliation of melanin-containing keratinocytes, and effectively avoid excessive melanin precipitation.
Using cosmetics-grade nicotinamide can achieve the whitening function we need, but before using it, we need to try it out to make sure it is suitable for our skin.
