The 10% TCA Depigmentation Peel is mild but very effective and delivers lighteners down to the melanocyte without traumatizing the skin. The TCA Peel is buffered with azelaic, arbutin, and kojic acids, which are tyrosinase inhibitors that control hyperpigmentation, melasma, or sun damage .The combination of these acids is a beautiful peeling treatment for evening skin tone, reducing acne, and retexturing the skin.
