Generally speaking, eating vitamin C can whiten the skin.

The color of skin mainly depends on the content of melanin in the skin, and the root of melanin production is arginase, so inhibiting the biosynthesis of arginase is the key to whitening.

It has been scientifically proved that vitamin C can inhibit the synthesis of this enzyme, hinder the production of melanin, protect the skin from ultraviolet rays, reduce the synthesized melanin to colorless melanin precursors, and improve the dullness of the skin, thus achieving the whitening effect.
