Our skin shows a wide ranging pH range from 4.0 to 7.0, but healthy skin will have a pH of 5.0 or less. Research says, that if left unwashed for 24 hours or more, skin’s pH can even drop below 4. The pH of your skin affects the bacteria’s that live on it’s surface. A pH level of 4 – 4.5 retains the resident bacteria on skin that keeps it healthy, Higher pH levels causes beneficial bacteria to be dispersed. Acidic water from an electric water ionizer like an AquaTatva (http://www.aquatatva.com ) acts as an astringent tightening the surface of the skin while maintaining healthy skin oil and pH levels. Acidic water can also help wash soap and hard water residues from the surface of the skin. Perhaps the most important benefit of Acidic water for skin is that it helps maintain your skin’s acids mantle which acts as a barrier to infection, the low pH kills bacteria, viruses, and molds that can cause skin and other health problems. Properly hydrated skin with a healthy pH doesn’t crack or peel either, which helps prevent infections.
