Acne: Neither of those medications are useful for acne dark spots. Neither of them are very useful in treating acne at all. The sulfa drug can help acne but can have very serious side effects so it is not routinely used. Whenever the skin is inflamed it will get lighter or darker in color. See your dermatologist to get the acne under control so you don't get scars and dark spots.
