Did You Know? Skin pH

By Rosemarie Colombraro

Your skin’s natural pH level hovers around a slightly acidic 4.7, but most skincare products have a pH of 6 or higher. This means your skin actually has to work harder to bring pH levels back to normal after you cleanse and moisturize, says cosmetic science consultant Johann Wiechers, PhD. The result? Dry, scaly skin. If this sounds like your problem, limit your use of skincare products with high pH formulations—such as soap—and opt for ones with natural alpha hydroxy acids, which are usually formulated at a low pH.
