The PCA SKIN philosophy is progressive, not aggressive.  These peels are applied using varying blends of peel solutions in a layering technique to determine the depth of penetration to either the surface or deeper, underlying tissue.  This technique is possible since PCA SKIN liquid peel formulations are self-neutralizing and the number of layers are determined by the PCA SKIN trained clinician.  After peel application, nutritive topicals and calming broad-spectrum SPF products are applied and the patient leaves with a glowing, healthy complexion.
