Alpha-hydroxy acids (AHAs) are a group of humectant molecules used as moisturizing agents. They impact the water content of the top layer of the epidermis (stratum corneum) by holding on to water. They also promote cell turnover by reducing cell cohesion and they improve skin barrier function by increasing levels of ceramides. AHAs include lactic & glycolic acid. Because they aid in exfoliating dry & rough skin, as well as enhancing skin hydration, they work well for dry skin conditions, like keratosis pilaris. They can sting a bit on application, particularly if the individual has sensitivity, is using other exfoliants, and/or has rosacea. The walgreens AHA face cream works well for improving the smoothness of facial skin and overall skin texture on the face. Amlactin brand of moisturizers for the body are likewise a good choice. You can get a free sample of amlactin on their website, FYI.
