Do chemical peels work for hyperpigmentation?

Yes. Chemical Peels are a great for treating hyper-pigmentation. There are several types of chemical peels with different and multiple chemicals in them. Chemical peels vary in depth and strength as well. Skin Medica's Vitalize peel uses salicylic, lactic, and resorcinol. All are great to lighten pigmentation. Glycolic acid peels are effective as well. Multiple peels are needed for maximum  results. Usually peels in  a series of 3-6 peels is standard. It is always important to consult a professional for the appropriate skin treatment for your skin type. 

Hyperpigmentation of any kind needs a combination approach of peels like Cosmelan; lasers like Clear + Brilliant, Aerolase or Laser Genesis; radiofrequency like Venus Viva; and constant skin care and sun protection. Bimonthly facials with SilkPeel DermalInfusion are essential to hydrate, exfoliate and infuse vitamins and antioxidants into the skin. If you have acne you can do additional treatments and peels to get more improvement. Hypopigmentation will need more of an evaluation and possibly additional lasers to get improvement. I suggest a formal consultation with an expert in lasers and peels. Best, Dr. Emer.

Chemical peels are an excellent treatment for hyperpigmentation. This can be done using chemical peels (generally, in my practice, this is a combination of salicylic acid, kojic acid, TCA, retinoic acid, Phenol Glutathione and Vitamin C) AKA THE PERFECT DERMA PEEL.  It has excellent results for aging skin, acne, melasma, hyperpigmentation. It may be used on the body as well.  You will have a peeling time of about 3-5 days.  Proper homecare instructions will be given to you at the time of visit.  Also Discussion of Routine home care after to maintain results.  Recommended 3 timed a year.
