With the convenience of at-home pH kits, you can potentially discover your skin's pH without seeking professional assistance. These kits usually come in the form of paper strips that you simply apply to your skin and then measure. To ensure accurate results, it's important to purchase pH kits specifically designed for skin use. While tests using saliva and urine can give a general reading of your body's pH levels, they won't provide specific information about the pH levels of your skin's surface.
