This soap is a game changer. Because it is formulated with oils known to be cleansing but gentle and non-drying it does not trigger excessive sebum production. Did anyone tell you that sebum is your friend? Your sebum is slightly acidic and is your defense against pathogens that come in contact with your face and may cause break outs. Aggressive soaps and cleansers strip away that sebum leading to your body doubling down and producing more than the necessary sebum to keep your skin safe. If your skin becomes oily a couple of hours after you wash your face, your face is reacting to the harsh soap you cleansed with earlier.
