The Soap Works Creamy Clay Cleansing Soap uses fine Bentonite clay which absorbs excess oil on the skin without drying. It cleans and tones all skin types and has an all vegetable content. This is a great all-purpose bar. It is designed for normal to oily skin. The bentonite clay is supposed to absorb surface skin oil without excessively drying the skin. The Soap Works believes that especially strong, astringent soaps used on naturally oily skin clear away too much surface oil causing the skin to compensate by over producing more oil, thereby exacerbating the problem.
