Depends on the cause. A dermatologist can look at facial spots to see how to remove them. Some spots go away with differin (adapalene) gel (also used to treat acne), even though the spots are not acne. Other spots go away after light freezing with liquid nitrogen. Lasers may be used for some spots. Other spots may be removed by scraping with a special blade. People who tan easily may get a new dark spot "scar" after spot removal.
