The Blue Peel is an in-office chemical peel that exfoliates surface layers of skin to treat acne, fine lines and wrinkles, scars, hyperpigmentation, and uneven tone and texture. Primarily used on the face, the Blue Peel can also be applied to the neck, chest, back, hands, and even arms and legs. Its acid solution causes layers of aging and damaged skin to peel away, revealing healthy new skin. Developed by Beverly Hills dermatologic surgeon Dr. Zein Obagi, it’s often called the Obagi Blue Peel.Â
The peel’s active ingredient is trichloroacetic acid (TCA), which is mixed with a blue pigment (hence the name) that helps your doctor see where the solution has been applied, for even distribution. The TCA “unglues” the dead layers of skin that are sticking to the surface and allows them to slough off. It can penetrate deeper than other exfoliating acids, like AHAs (glycolic acid, lactic acid) and BHA (salicylic acid), for more significant results.
For the peel, “15% TCA is recommended for normal, sensitive, dry, or thin skin for lighter exfoliation, and 20% is recommended for thicker skin or someone who needs more correction,” says Dr. Joseph Hunstad, a board-certified plastic surgeon in Huntersville, North Carolina, in a RealSelf Q&A. Either way, it’s an intense acid preparation that should be applied only in a doctor’s office by a qualified medical professional.
