There are many chemical peels on the market today. Medical-grade peels are going to be the best when it comes to treating Melasma. Topical home care is very important too. If you can’t use hydroquinone, other options are Kojic acid, Vitamin C, Licorice Extract, Arbuti, or a blend of them). And of course most importantly is being religious about sun protection i.e. hat, sunglasses, etc.. and a good sunblock repeatedly applied every hour! In our experience, we have found the Perfect Derma Peel for Melasma works very well. The active ingredients are: TCA, Retinoic Acid, Salicylic Acid, Kojic Acids, Phenol, Glutathione and Vitamin C. So with the cell turnover you also have antioxidants that inhibit melanin production and brighten the skin. Hope you found this answer helpful. All the best!
