OBAGI'S BLUE PEEL
The Obagi Blue Peel uses Trichloroacetic Acid (TCA) as the active ingredient mixed with the patented Blue Base from Obagi. By the seventh to tenth day after peeling begins, your skin should be healed. Once your skin has completely recovered and is finished peeling, you will notice a visible improvement in your complexion. Your skin's appearance will continue to improve over the next six weeks, becoming firmer, clearer, smoother, healthier and more youthful looking.
