They may be either naturally occurring or synthetic. 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.

Beta hydroxy acid
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 are often found in products that aid in the reduction of wrinkles as well as to soften strong, defining lines and improve the overall look and feel of the skin.
Alpha hydroxy hiddoxiacidos Cosmetics chemicals.
A clinical, histological, and ultra-structural study. Understanding skin structure and cutaneous aging is helpful to a discussion of the hidroxiaciods action of AHAs. In other projects Wikimedia Commons.
AHAs are a group of organic carboxylic compounds.
Beta hydroxy acid – Wikipedia
Cutaneous aging, while having epidermal concomitants, seems to involve primarily the dermis and is caused by intrinsic and extrinsic aging factors. 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.

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.
Improvement of photodamaged skin with alpha-hydroxy acid AHA: Bioavailability influenced primarily by small molecular size is an important factor in a compound’s ability to penetrate the top layer of the skin.
Rapid Communications in Mass Spectrometry. For any topical compound to be effective, including AHA, it must penetrate into the skin where it can act on living cells. It is important to understand that glycolic acid peels are chemical peels with similar risks and side effects as other peels. AHAs most commonly used in cosmetic applications are typically derived from food products including glycolic acid from sugar canelactic acid from sour milkmalic acid from applescitric acid from citrus fruits and tartaric acid from grape wine.

Two effects emerge from this situation:. AHAs have a profound effect on keratinization ; which is clinically detectable by the formation of a new stratum corneum. AHAs with greater bioavailability appear to have deeper dermal effects.
