Under a mask, the skin secretes more than twice the normal amount of sebum, creating conditions similar to those in a tropical rainforest! That's why we developed a facial soap that solves problems like stickiness caused by stuffiness under a mask, acne, breakouts, and unpleasant sebum odor. Thoroughly removes excess sebum and controls sebum production for clean, beautiful skin. It even reaches behind the ears, where dirt and sebum tend to accumulate due to the friction of mask strings. The clean, soapy scent helps to eliminate odors inside the mask even after washing. Of course, to prevent dryness caused by excessive sebum removal, it protects your skin with moisturizing ingredients similar to sebum and ingredients that treat skin problems like acne. The cleansing ingredients are derived from plants and are free of preservatives, alcohol, mineral oil, synthetic colorings, and petroleum-based surfactants. Enjoy a comfortable mask life with Beta Barrier, which treats rough skin caused by masks.
