In a previous Hub, the question was posed - "Are OTC Anti-Aging Skin Care Products All They're Cracked Up to Be?". This is the first in a series of articles covering the anti-aging skin care ingredients commonly found in these products.

Over 200 manufacturers of skin care products in the United States include Alpha Hydroxy Acids (AHAs) in their formulations. This substance is promoted primarily as an agent for reducing fine lines and wrinkles, irregular pigmentation and age spots, and decreasing the size of enlarged pores. AHAs are drawn from fruit and milk sugars and are contained in a profusion of skin creams and lotions. In higher concentrations they are used as chemical peels.

The United States Food and Drug Administration (FDA) recommends using skin care products with an AHA concentration of 10 percent or less and a pH of 3.5 or greater. The FDA has received a string of reports indicating increased sensitivity to the sun from use of skin care creams, etc. with AHAs due to the exfoliant properties. Accordingly, the FDA has issued a recommendation that product labeling bear this warning:

"Sunburn Alert: This product contains an alpha hydroxy acid (AHA) that may increase your skin's sensitivity to the sun and particularly the possibility of sunburn. Use a sunscreen, wear protective clothing, and limit sun exposure while using this product and for a week afterwards." For additional information, Click Here.

Products for consumers containing Alpha hydroxy acid must have a concentration of less than 10%. A concentration of 20% to 30% may be used by trained cosmetologists for chemical peels yielding results akin to microdermabrasion with erasure of fine lines and producing a smoother skin appearance. One to three applications may be required.

So, it's clear that Alpha Hydroxy Acid (AHA) has a credible measure of science behind it. For more information please visit the article, Anti Aging Skin Care Using AHAs (Alpha Hydroxy Acids).
