The Obagi Blue Peel is a superior chemical peel that achieves optimum skin resurfacing by using slow-acting TCA (trichloroacetic acid) to remove dead skin cells and stimulate the production of new ones. The Obagi Blue Peel is considered a “medium depth” facial peel because it is stronger than the popular Glycolic Acid Peel and requires less recovery time than a full Laser Resurfacing, therefore falling in-between the two treatments with respect to results and recovery time.
