Why the natural konjac sponge balance skin pH?
The normal pH of people's skin is 5-6.5, which is weakly acidic. If the pH is too high, the skin will be aging soon. However, if it is too low, the skin will be also sensitive. Therefore,the pH during 5.5 and 7 will be the best. When the pH value is 5.5-7, no matter whether the human skin is acidic or alkaline, due to the sputum-specific glucoside (Glucan KGM) fiber network, the water content of the skin keratinocytes can be maintained by regulating and storing water , so that it can neutralize, balance the pH value, and finally achieve skin care.
