Our skin has a protective layer of acidic oils that act as a barrier and filter, protecting the inside of the body from the external environment. This layer is called the acid mantle. The skins PH is between 4 to 5.5, making it acidic. It is this acid layer that protects the skin from bacteria, killing the bacteria so that it cannot damage the skin.
Most commercial soaps are a strong alkaline that strip the acid mantle from the skin, making it easy for bacteria to attack. Goats milk however has a PH that is very similar to that of the skins natural PH making goat’s milk soaps a very popular soap that neutralize the effects of bacteria that cause skin infections. The very best way you can maintain your acid mantle is to use skin care products such as goat milk soap that are PH balanced.
