AHAs with greater bioavailability appear to have deeper dermal effects. Human skin has two principal components, the avascular epidermis and the underlying vascular dermis. The severity usually depends on the pH and the concentration of the acid used. Retrieved from ” https: 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.

Bera material may be challenged and removed. Some of the side effects of AHAs chemical peeling can include hyper-pigmentation, persistent redness, scarring, as well as flare up of facial herpes infections “cold sores”.

Bulletin of the Chemical Society of Japan. Glycolic acid, lactic acid, and citric acid, on topical application to photodamaged skin, have been shown to produce increased amounts of mucopolysaccharides and hidroxicidos and increased skin thickness without detectable inflammation, as monitored by skin biopsies.


June Learn how and when to remove this template message. AHAs have a profound effect on keratinization ; which is clinically detectable by the formation of a new stratum corneum. It appears that AHAs modulate this formation through diminished cellular cohesion between corneocytes at the lowest levels of the stratum corneum. Improvement of photodamaged skin with alpha-hydroxy acid Hidroxuacidos A clinical, histological, and ultra-structural study.

For any topical compound to be effective, including AHA, it must penetrate into the skin where it can act on living cells. Indian Journal of Dermatology, Venereology and Leprology.

Newer formulations combine glycolic acid hidroxiaciros an amino acid such as arginine and time-release formulations that reduces the risk of irritation without affecting glycolic acid efficacy. This article needs additional citations for verification.
