PCA Skin peels are not timed, neutralized or removed from the skin. Instead, they are self-neutralizing and are left on the skin. The strength and depth of the treatment is controlled by the trained professional based on the number of layers applied during treatment. After the peel application, nutritive topicals and calming, broad-spectrum SPF products are applied, you will leave with a glowing, healthy complexion. An after peel kit will be given to you to take home.
