What does PH stand for?
Potential Hydrogen. It is used to describe the acid-alkaline ratio of a substance, which ranges from 0 (the most acidic) to 14 (the most alkaline). The health of your body—and skin—is directly linked to maintaining the right balance between acidity and alkalinity.
How so? The skin’s barrier, which is known as the acid mantle, is responsible for keeping in lipids and moisture while blocking germs, pollution, toxins, and bacteria.
To work its best, the acid mantle should be slightly acidic, at a 5.5 pH balance. When your skin is too alkaline, it can become dry and sensitive. Over exfoliation can damage your skins barrier and in turn affect your skins PH level.
Maintaining a healthy PH balance within your body is also extremely important – in some cases, an over acidic body may lead to your tan turning green.
