If the skin supersession is not smooth, will cause a large amount of pigment to precipitate, and assemble in the part, it causes the skin irregularity that the color of the skin will strengthen or form the spot. It is the key to whitening to so inhibit the biosynthesis of enzyme hydroxyphenylaminopropionic acid and prevent suntan. And vitamin C can inhibit the activity of enzyme hydroxyphenylaminopropionic acid, block the melanin to turn into, protect skin from receiving the injury of ultraviolet ray, reduce the melanin already formed into a quality before the colourless melanin, and improve obscure result of the skin.
