Hi.... Wash problem areas with a gentle cleanser. Twice a day, use your hands to wash your face with a mild soap and warm water..... For these spots you can use cocoa butter or vitamin E creams. Topical treatments with acids and chemical peels can be effective but can take a while for the skin to totally revert to its normal color.  Microdermabrasion can also be done, but this might require several sessions.  Skin resurfacing using lasers is also an option....
