The normal pH level our skin is between 5.0 and 5.6. Nature has given us perfectly balanced skin which lies between Acidic and Neutral. Our skin borders on the acidic side which prevents bacteria from growing. If you use a hand soap to wash your face, your pH level could increase and could even rise to somewhere between 5.7 and 6.8 which would give you a very strong alkaline level making it the perfect incubator for growing bacteria. Detergents remove grease and dirt leaving your hands, clothes and dishes feeling squeaky clean. It also leaves your face or hands feeling very dry. These types of detergents drain all the oil and moisture from your skin. So for a person with oily skin, you might feel better in the short run, but you will soon realize that the more you use it, the more your skin will turn from oily to dry. You must maintain the proper balance of oil in your skin to prevent your body from manufacturing excessive oils.
