It appears that AHAs modulate this formation through diminished cellular cohesion between corneocytes at the lowest levels of the stratum corneum.
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.
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”. AHAs have a profound effect on keratinization ; which is hidorxiacidos detectable by the formation of a new stratum corneum. Principles of organic hidroxiaxidos. AHAs are bet known for their use in the cosmetics industry.
Views Read Edit View history. Bioavailability influenced primarily by small molecular size is an important factor in a compound’s ability to penetrate the top layer of the skin. It is important to understand that glycolic acid peels are chemical peels with similar risks and side effects as other peels. Moy; Debra Luftman; Lenore S.
Alpha hydroxy acid – Wikipedia
