Alpha hydroxy acid Questions and
Answers
Alpha hydroxy acid - answer α-Hydroxy acids, or alpha hydroxy acids (AHAs), are a
class of chemical compounds that consist of a carboxylic acid substituted with a
hydroxyl group on the adjacent carbon.

They may be naturally occurring or synthetic. AHAs are well known for their use in the
cosmetics industry. They are often found in products that aid in the reduction of
wrinkles, that soften strong, defining lines, and that improve the overall look and feel of
the skin. - answer They are also used as chemical peels. AHAs have effective
results through continuous treatment in the cosmeceutical industry.

Cosmetic applications - answer Human skin has two principal components, the
avascular epidermis and the underlying vascular dermis. For any topical compound to
be effective it must pass the epidermal layer and reach the live cells within the dermis.
[citation needed]

AHAs are a group of organic carboxylic compounds. - answer AHAs most commonly
used in cosmetic applications are typically similar to those found in food products
including glycolic acid , lactic acid , malic acid , citric acid and tartaric acid

— though the source of the AHAs in cosmetics is predominantly synthetic or from
bacterial or fungal fermentations. - answer For any topical compound to be effective,
including AHA, it must penetrate into the skin where it can act on living cells.

Glycolic acid, having 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. - answer Epidermal effect

AHAs have a profound effect on keratinization, which is clinically detectable by the
formation of a new stratum corneum. - answer It appears that AHAs modulate this
formation through diminished cellular cohesion between corneocytes at the lowest
levels of the stratum corneum.[citation needed]

Dermal effects - answer AHAs with greater bioavailability appear to have deeper
dermal effects.

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 - answer Alpha hydroxy acids at different concentrations
