I had scleroderma and it left a scar that resembles a burn/discoloration. i sometimes get depressed due to color. what's the best cream to be normal?

Morphea: It sounds like you had the localized form (also called morphea). Retin-a (tretinoin) cream will sometimes help with those types of scars, though it is an off-label use, and improvement is slow. There are plastic surgery options too, depending on where the scar is located. A dermatologist can help you decide on the best course of action.
