Lactique, Acide L'acide lactique est un acide organique qui joue un rôle dans divers processus biochimiques. Un lactate est un sel de cet acide. Contrairement à ce que peut laisser penser son nom, l'acide lactique n'est pas présent uniquement dans le lait, mais également dans le vin, certains fruits et légumes, et dans les muscles.
L'acide lactique est un acide alpha hydroxylé, sa formule chimique est C3H6O3 et sa structure se reflète dans son nom systématique, l'acide 2-hydroxypropanoïque.

| Résumé : |
The stratum corneum water barrier controls structural and functional properties of both the epidermis and the dermis. Treatments which chronically disrupt the stratum corneum water barrier can induce changes similar to those seen with ’anti-aging’ treatments such as (-Hydroxy acids (AHAs) and Retin A™.
Barrier disruption via daily tape stripping increases epidermal and dermal thickness, superficial and integral skin firmness, and improves skin surface texture. Modest or transitory disruption did not produce such effects. Similar results were observed with topical application of AHAs, retinoids or mild irritants after about 4-6 weeks provided such treatments resulted in prolonged elevation in TEWL (trans-epidermal water loss). Treatments that did not chronically elevate TEWL could also produce positive cosmetic effects, but such effects were in general restricted to the skin surface or epidermis. Irritation, which was observed with some treatments, was not solely responsible for the positive effects observed. |
