Treatment of Hyperpigmentation
Retina-A does not treat hyperpigmentation well, though it does treat acne well, especially if you have significant clogged pores. Hydroquinone is needed to treat the pigmentary problem that invariably accompanies acne. This can be added to your regular acne treatment or can be used as the Obagi Nu-Derm system as the major acne therapy to which you can add an antibiotic. See a physician with significant experience in treating acne as well as hyperpigmentation.
