The Obagi Blue Peel is designed to improve the appearance and health of your skin. Using a low concentration of the chemical trichloroacetic acid (TCA) mixed with a patented base to monitor the appropriate depth, the peel effectively removes the surface layers of aged and damaged skin from the face or other parts of the body. The dead skin cells are replaced by healthier cells, allowing the skin’s own clarity and tightness to resurface. Depending on skin type and desired results, one or more layers are applied. When your skin has completely finished peeling, you will immediately notice the dramatic results of your newly improved complexion. The skin will be firmer, clearer, smoother, healthier and more youthful looking.
