pigmentation ?
u r in ur early 20's right ?
u can try using forever living product. try the Epiblanc.

This exclusive formula of Epiblanc is specifically designed to brighten the complexion and even out our sometimes patchy skin colour.
It also helps diminish the appearance of dark spots (for example liver spots which we get on our face, backs of arms and hands, which are usually the areas most exposed to the sun).

With 100% stabilised Aloe Vera Gel as the base and carrier for the natural botanical extracts such as Arbutin (Bearberry), Rumex Occidentalis, and natural Vitamin E this fine combination of ingredients results in yet another fine FLP product.

Most effective applied directly to blemishes or dark spots.
