pH
Directly defined as power of the hydrogen molecule. Amount of hydrogen present in a substance determines the acid or alkaline level of a product. In the skin it is the pH of the acid mantle (the protective fluid made up of perspiration, oils and other debris lying over the horny layer) considered important to the health of the skin. pH at the skin surface normally is between 4.5 and 5.5
