The Obagi Blue Peel uses a topical solution to treat a variety of dermatology issues, such as sun damage, hyperpigmentation, fine lines and wrinkles, and acne scarring. It leaves patients with rejuvenated, younger-looking skin. The Obagi Blue Peel causes your dead skin cells to shed, revealing a layer of soft, new skin underneath. It also stimulates collagen production underneath your skin. The Obagi Blue Peel solution combines two ingredients: TCA (trichloroacetic acid), which cleans out your pores and refreshes your skin cells, and a blue base. The blue base allows your provider to control the depth of the peel, so they can tailor the treatment to each patient. Because this peel can be customized, it can treat more parts of the body, and more skin types.
