Antibacterial Cleanser is designed for acne clients with normal to oily skin. It provides maximum bacterial control using a specific extract from cinnamon bark to inhibit the action of 5 alpha reductase, including its acne promoting actions in the sebaceous glands. *One percent of the population is allergic to topical cinnamon extract and will develop redness and stinging following use on approximately the second or third day. In the rare case — switch to Bacteriostat Cleanser or Vivant Cleansers.
