Step 1: Apply Vitamin C Resurfacing Mask (about the size of a quarter) to clean, dry face. Cover entire face with mask, avoiding the eye area, and gently massage for up to 1 minute. Step 2: Apply generous amount of AHA Peel Activator to face over resurfacing mask. The two formulas combine to create a white foam and gentle warming sensation. Massage until resurfacing crystals dissolve for up to 1 minute. Rinse thoroughly with warm water and pat skin dry.
