Our PCA line has so many products to offer for all skin types from Fitzpatrick 1-6. PCA peels are "Self Neutralizing" and do not need to be rinsed off or neutralized. Our BioRepeel is one of the most advanced peels in the industry, where results are fast and flake free! Please remember that optimum results are based upon regular treatments and maintenance. Just like exercising, 1 workout doesn't make you fit, consistency is the key.
