Alpha hydroxyl acids (AHAs) are one of the most common ingredients in many skin care beauty products and can be a great asset for women who want to reduce the appearance of fine lines and wrinkles. But have you ever wondered just how these acids have such a powerful effect on skin in the first place?
A recent study by the University of California Davis and Peking University focused on the effects that AHAs have on skin physiology and keratinocytes - the most dominant cell type in the epidermis - in an effort to figure out why these potent wrinkle-fighters work as well as they do.
Researchers found that cultured cells that are exposed to glycolic acid, one of the smallest yet readily available AHAs, quickly develop more acidity. As these levels rise, pH becomes lower, making calcium ions more likely to infiltrate the cell. This can create a calcium overload inside, causing the cell to perish and skin to become exfoliated, one of the many functions of AHAs.
While this study establishes how AHAs work on a cellular level, further research is needed to learn more about this vital anti aging resource. For a product that harnesses the power of AHAs, consider something like La Therapie Creme Regenerante Regenerating Night Cream for radiant skin.
