Product Introduction
Retinol cannot exist alone, is unstable and cannot be stored, so it can only exist in the form of acetate or palmitate. This is a fat-soluble vitamin that is stable to heat, acid and alkali, and is easily oxidized. Ultraviolet rays can promote its oxidative destruction.
Function
Retinol can effectively scavenge free radicals, prevent the decomposition of collagen, and slow down the formation of wrinkles. It also takes into account the dilute melanin, whitening and brightening the skin.
