The second 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 down 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. The actual concentration of AHA in this product is not clearly indicated but on the other hand it is listed as the 4th ingredient which means the concentration is quite significant.

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 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. I would have rated it higher but the price is hard to justify.

One thing I need to point out about the ingredient triethanolamine (TEA). The problem with TEA is that like all amines, it has the potential for creating nitrosamines. It may or may not. There is no way of knowing, at least without a well-equipped chemistry lab. But it will be really bad if it does. Nitrosamines are readily absorbed through skin and they have been proved to be strong carcinogen. Whether or not the concentrations used in cosmetics should be of concern is still a matter of debate. It is suggested to best avoid products containing TEA.

Safety alert: Cautious
review based on scientific information of the product ingredients.

1st ingredient		is water.
2nd ingredient		glycolic acid is alpha hydroxy acid (AHAs). AHAs are used to treat photodamaged skin and increase skin thickness. It has been proved effective against many aging-related skin conditions.
3rd ingredient		L-tyrosine is an amino acid and antioxidant. But whether the benefits can be translated into skin care has not been demonstrated.
4th ingredient		thioctic acid (alpha lipoic acid) reduces free radical damage and help delivery of antioxidants.
