A thorough understanding of Asian skin is essential for this treatment. Hyperpigmentation is tricky and constant attention to sun avoidance is necessary for continued success. I have like both a combination of chemical peels, bleaching agents, and topical Vitamin C for the best results. I have also had great success with Cosmelan medical grade peels. Please find a board certified dermatologist with a great deal of experience in Asian skin for the best results.
