Retinol is, by far, one of the most multifunctional ingredients in skin care.  Scientifically-proven to promote healthy cell turnover, increase collagen and elastin production, reduce follicular keratinization and inhibit dark spots on the skin, retinol benefits all skin types and conditions.  Perhaps one of its greatest properties is its ability to enhance in-office treatment outcomes.  These excellent additions are some of the most versatile professional treatments offered by PCA Skin (R), as they can be used alone or as boosters to any office procedures.  These excellent additions allow the technician to safely and effectively increase the benefits and visible flaking of their treatment without creating undue inflammation.  Ultra Peel II is good for dry or dehydrated skin and Esthetique Peel is good when treating acne, hyperpigmentation, rosacea or oily skin.
