What the product description says
“cleanser sweeps away dirt, impurities”
Source: Lookfantastic CA

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (glyceryl stearate se, lauric acid, myristic acid, peg-7 glyceryl cocoate, sodium methyl cocoyl taurate, stearic acid, xanthan gum) and should be able to cleanse the skin gently. Still keep in mind that any cleansing can disrupt the skin barrier, and most people do not need to cleanse their skin more than once per day.

Even though this formulation is mild, the following cleansing agents could trigger an irritation or allergy for some people: sodium methyl cocoyl taurate
