Potential hydrogen (pH) refers to the acidity level of substances, on a scale ranging from 1 to 14, with 7 considered neutral. A healthy skin pH is more acidic, with levels ranging from 4-7, and the optimum level considered around 5. Your skin needs to have a certain level of acidity to combat potentially harmful free radicals and microbes. Your skin pH can be determined by at-home tests, seeing a dermatologist or careful observation, for instance, acne, inflammation and dry patches may be signs of a more alkaline profile. To help keep your skin balanced, it is important to choose mild, hydrating cleansers that maintain the skin’s pH balance.
