We suggest that you only apply your nighttime Regimen routine after the Pore Cleansing MD System. The two other products that could be added include ENHANCEMENTS Active Hydration Serum to hydrate the skin. Layer between cleaning, toning and your remaining Regimen products. As well as SOOTHE Sensitive Skin Treatment to help minimize visible redness and to calm skin. And this way you have another night to pamper yourself!
