The only amino acid I can find in this product is the second ingredient L-tyrosine. Amino acids are the building blocks of proteins and have antioxidant properties. But whether the benefits can be translated into skin care has not been demonstrated.
The third abundant ingredient is urea. Urea in small amounts has good water-binding and exfoliating properties for skin; However in this product there is so much of it that it can cause inflammation.
The fifth abundant ingredient is glycolic acid (alpha hydroxy acid, AHAs). There is a lot of debate over AHA use in cosmetics. Concentration below 10% is considered useless. When the concentration is over 10%, AHA exfoliates upper layer skin by breaking the connective tissues between cells. This “chemical peel” reveals newer and more youthful looking skin. Also glycolic acid draws moisturizers into the newly-exfoliated skin surface. However, AHAs can leave skin extremely sensitive, especially to sun rays. So always wear sunscreen after use.
There are soothing ingredients in the product to comfort urea or AHA-irritated skin.
The ingredient DMAE has only reported to prevent aging based on a small study by Dr.Perricone himself, the manufacturer of the brand. So the claims are not solidly supported.
The product is richly moisturizing and contains good antioxidants to prevent future aging. In addition it is virtually irritants-free.
