Hydroquinone: One of the most effective treatments for "skin stains", or darkening of the skin after acne, is hydroquinone. It is available without a prescription in 2% strength and should be applied twice daily to the dark spots only, not the surrounding normal skin. Some formulations contain glycolic acid, which help as well. It often takes 6 or more weeks to see any improvement.
