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.
The benefit of such short-contact application chemical peels depends on hidroxiaicdos pH of the solution the more acidic the product, or the lower the pH, the more pronounced the resultsthe concentration of Hidroxiacios higher concentrations produce more vigorous hicroxiacidosthe length of application and prior skin conditioning such as prior use of topical vitamin A products.
Indian Journal of Dermatology, Venereology and Leprology. A clinical, histological, and ultra-structural study. AHAs are a group of organic carboxylic compounds. Unsourced material may be challenged and removed. AHAs have a profound effect on keratinization ; which is clinically detectable by the formation of a new stratum corneum.

Beta hydroxy acid
From Wikipedia, the free encyclopedia. Glycolic acid, lactic acid, and citric acid, on topical application to photodamaged skin, hidroxiscidos been shown to produce increased amounts of mucopolysaccharides and collagen and increased skin thickness without detectable inflammation, as monitored by skin biopsies. Moy; Debra Luftman; Lenore S. AHAs are generally safe when used on the skin as a cosmetic agent using the recommended dosage.
The Hidroxiacidoe 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. AHAs most commonly used in cosmetic applications are typically derived from food products including glycolic acid from sugar canelactic acid from hidroxiiacidos milkmalic acid from applescitric acid from citrus fruits and tartaric acid from grape wine.
AHAs are well known for their use in the cosmetics industry. Newer formulations combine glycolic acid with an amino acid such as arginine and time-release formulations that reduces the risk of irritation without affecting glycolic acid efficacy.

James; Bada, Jeffrey L. James Morriss3rd. European Academy of Dermatology and Venereology. Cutaneous aging, while having epidermal concomitants, seems to involve primarily the dermis and is caused by intrinsic and extrinsic aging factors.
Alpha hydroxy acid – Wikipedia
Bioavailability influenced primarily by small molecular size is an important factor in a compound’s ability to penetrate the top layer of the skin. Human skin has two principal components, the avascular epidermis and the underlying vascular dermis. Improvement of photodamaged skin with alpha-hydroxy acid AHA: Please help improve this article by adding citations to reliable sources. Understanding skin structure and cutaneous aging is helpful to a discussion of the topical action of AHAs.
They are often found in products that aid in the reduction of wrinkles as well hidroxiacidis to soften strong, defining lines and improve the overall look and feel of the skin. In other projects Wikimedia Commons.
Two effects emerge from this situation:. June Learn hidroxiacidis and when to remove this template message. AHAs with greater bioavailability appear to have deeper dermal effects. Ullmann’s Encyclopedia of Industrial Chemistry. Views Read Edit View history.
It is important to understand that glycolic acid peels are chemical peels with similar risks and side effects as other peels. The most common side-effects are mild skin irritations, redness and flaking. The severity usually depends on the pH and the concentration of the acid used. 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.
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.

For any topical compound to be effective, including AHA, it must penetrate into the skin where it can act on living cells. 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.
They may be either naturally occurring or synthetic. Principles of organic synthesis.
