Good skin care is built upon a good foundation. Our Preparation Peels underwrite your skin's ongoing well being. We offer four varietals for different skin conditions and needs. Gentle, effective cleansing and exfoliation is assured. Well cleansed and exfoliated skin is Step 1 in a complete skincare regimen. Apply once a day before retiring. These products are gentle to the skin, so can be used more frequently if desired, or even left on overnight.
