Advanced Clinicals, Retinol Serum, Anti-Wrkle, 1,75 Fl Oz (52 ml)

After cleansing, allow skin to dry completely. Gently pat retinol serum across face, focusing on problem areas. Wipe excess onto the backs of your hands, as these are often exposed to sun damage. Allow a few minutes to absorb. Use every night before bed. Redness, tightness, or flushing may occur. This is normal and means the product is working. If irritation persists, reduce frequency of use every other night. Gradually increase use each night as tolerated. As with any product, if a rash develops, discontinue use and consult your physician.
