Most experts we spoke to say the ideal skin pH is slightly acidic to ward off bacteria and toxins, around 5.5. However, Heskett points out that studies have now shown that the most natural pH for skin is 4.7. "At 4.7, the skin has optimal barrier protection, moisturization and scaling," she explains. "Additionally, this pH does the best job at keeping the resident bacteria (the good bacteria) attached to the skin surface. At higher pH's this bacteria is more easily dispersed, which leaves skin unprotected."
