The pH (potential of hydrogen) of healthy human skin is slightly acidic, ranging from 4.7 to 5.75. This acidic environment, known as the "acid mantle," is important for maintaining skin health by:
-Protecting against bacteria and fungi: The acidic pH inhibits the growth of harmful microorganisms.
-Regulating skin cell turnover: The acid mantle helps to shed dead skin cells and promote the formation of new ones.
-Maintaining moisture balance: The acidic pH helps to attract and retain water in the skin.
