I woke up, face tight and shinny!! Which mean the product is working, YAY! I did a four layer peel which is the max for the PCA Sensi Peel. I used a retinoid treatment booster (which is loaded with antioxidants, polyphenols, vitamins, humectants and brightening/firming agents) and multifunctional serum that helps reduce discoloration, bacteria and excess oil which leads to clearer, even skin.
