The Bar has a non-soap formula. Soasps generally have a ph of 10.0 or higher (very alkaline) while The Bar from Dermalogica is acid balanced to the at ph 5.5. The Bar is everything that soap isn't. In fact, it performs like your favorite Dermalogica Cleanser, in convenient bar form! The Bar is the opposite of harsh, alkaline soaps. Made with non-animal-derived cleansing agents that are acid-balanced to the skin, The Bar gently cleanses away clogging debris and excess oils without leaving the face taut or dry. As always, this soap-free bar is completely free of irritating artifical fragrances and colors found in most soaps, making it ideal for even the most sensitized skin.
