What it is Choosing a cleanser involves finding a balance between thorough cleansing and maintaining the skin's barrier health. Our Green Plum Refreshing Cleanser, with its gentle, slightly acidic formulation, harnesses the power of plant-derived extracts from plum and mung bean seeds to achieve just that. Hypoallergenic, slightly acidic formula Healthy skin is slightly acidic because of the acidic components secreted by the sweat and sebaceous glands. When these acidic components decrease, the skin's defense weakens, making it easy for the skin to become sensitive. Green Plum Refreshing Cleanser is a slightly acidic cleanser that helps to cleanse the face without damaging the natural skin barrier.
