I hav brown pigments on my face..im 22 .how to get rid of them...i dnt go out in sun..pls help?

Ahhh..I used to suffer from the same problem my dear. I totally understand. Please do consult doctor and use the products that the doctor recommends religiously. It will definitely work. It will not go in a few days or weeks, it will take months to go. I know you would be frustrated after hearing this.
