Health Watch -- Younger Skin: Hydroxy Acids
Health Watch is a Public Service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.
On Health Watch this week we're talking about keeping your skin looking young. Previously, we talked about how sunscreen can help prevent aging skin and retinoids can reverse some signs of aging. Another product you should look for is hydroxy acids.
Hydroxy acids can include glycolic acid, lactic acid or salicylic acid. Among other beneficial actions, they help stimulate collagen for smoother, fresher-looking skin. Dr. Sarah Weitzul, an expert on cosmetic dermatology at UT Southwestern Medical Center at Dallas, says you shouldn't choose a product with a "soup" of all these ingredients. Instead, find a cream with one of these acids as a single ingredient. The most effective products are those with pH3 or pH4 acidity levels.
