The optimal pH value for most skin on the face and body is between 4.7 and 5.75. This means that skin is naturally acidic. A pH of 7 is considered neutral, like pure water. Anything below 7 is acidic, and anything above 7 is alkaline.
Skin's pH is important for maintaining a healthy skin barrier. The acidic environment helps to protect the skin from harmful microbes and damaging free radicals. When the skin's pH is too alkaline or overly acidic, it can lead to issues like acne, inflammation, and premature aging.
To maintain a healthy skin pH, it's important to use gentle cleansers and pH-balanced skincare products. Soaps, shampoos, toners, cleansers, lotions, and beauty products should be neutral or even slightly acidic to maintain the skin's ultimate pH level.
Here are some additional things to keep in mind about skin pH:
- Factors that can affect skin pH: Environmental factors like pollution, sleep, hydration, and the products used on the skin can all affect skin pH.
- Importance of pH-balanced skincare: Using products with a pH that matches the natural pH of the skin can help to maintain a healthy skin barrier.
- Testing your skin's pH: If you are concerned about your skin's pH, you can purchase pH test strips from a drugstore or online.
