After cleansing your skin thoroughly, apply a thin layer to clean skin. You may experience a slight tingling as the mask dries. That is to be expected as it works to gently exfoliate and resurface the skin. Leave on until the mask is dry. Rinse with warm water. Tips for usage: For the first week, use every other day for best results. Then use the Refresh Mint 2 to 3 times per week to maintain results. Follow the mask with The Optimist Hydrating Essence and the Super Couple, the Supercritical facial oil or Super Blend pressed serum moisture concentrate for the best results. Sensitivity & Sunburn Alert: This product is quite active, as it contains four acids; for people with sensitive skin, we recommend testing this product on a small patch of skin first, and then leaving it on for a shorter time (ie before it dries), until your skin gets used to it. Discontinue use if allergic reaction occurs. Since it contains an alpha hydroxy acid (AHA), which may increase your skin’s sensitivity to the sun and particularly the possibility of sunburn, use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards.
