Alpha hydroxy acid
Cutaneous aging, while having epidermal concomitants, seems to involve primarily the dermis and is caused by intrinsic and extrinsic aging factors. The most common side-effects are mild skin irritations, redness and flaking. Understanding skin structure and cutaneous aging is helpful to a discussion of the topical action of AHAs. Low concentration makes possible daily application as a monotherapy or as part of a broader skin care management for such conditions as acne, photo-damage, wrinkling as well as melasma.
AHAs are generally safe when used on the skin as a cosmetic agent using the recommended dosage.

A clinical, histological, and ultra-structural study. Alpha hydroxy acids Cosmetics chemicals. It is important to understand that glycolic acid peels are chemical peels with similar risks and side effects as other peels.

James Morriss3rd. AHAs most commonly used in cosmetic applications are typically derived from food products including bta acid from sugar canelactic acid from sour milkmalic acid from applescitric acid from citrus fruits and tartaric acid from grape wine. The benefit of such short-contact application chemical peels depends on the pH of the solution the more acidic the product, or the lower the pH, hidroxiacidks more pronounced the resultsthe concentration of GA higher concentrations produce more vigorous responsethe length of application and prior skin conditioning such as prior use of topical vitamin A products.
Glycolic acidhaving the smallest molecular size, is the AHA with greatest bioavailability and penetrates the skin most easily; this largely accounts for the popularity of this product in cosmetic applications.
The FDA has also warned consumers that care should be taken when using AHAs after an industry-sponsored study found that they can increase photosensitivity to the sun.
It appears that AHAs modulate this formation through diminished cellular cohesion between corneocytes at the lowest levels hisroxiacidos the stratum corneum. Two effects emerge from this situation:.

For any topical compound to be effective, including AHA, it must penetrate into the skin where hidrpxiacidos can act on living cells.
Although these compounds are related to the ordinary carboxylic acidsand therefore are weak acids, their chemical structure allows for the formation of an internal hydrogen bond between the hydrogen at the hydroxyl group and one of the oxygen atoms of the carboxylic group. Unsourced material may be challenged and removed. The severity usually depends on the pH and the concentration of the acid used. Please help improve this article by adding citations to reliable sources. AHAs have a profound effect on keratinization ; which is clinically detectable by the formation of a new stratum corneum.
AHAs are a group of organic carboxylic compounds.

Beta hydroxy acid – Wikipedia
Chemical peels tend to have more severe side-effects including blistering, burning and skin discoloration, although they are usually mild and go away a day or two after treatment. They may be either naturally occurring or synthetic. Glycolic acid, lactic acid, and citric acid, on topical application to photodamaged skin, have been shown to produce increased amounts of mucopolysaccharides and collagen and increased skin thickness without detectable inflammation, as monitored by skin biopsies.
