Hypohalous Acid (hypochlorous acid, hypobromous acid, or hypoiodious acid) is an exfoliating ingredient that are included in anti-acne medications. Typical products that include these acids are solutions, cleansers, lotions, creams, facial masks and gels. They are scrubbed onto the skin either by hand, or with a cloth, sponge, brush or spraying device. The idea behind these acids is to remove the outermost layer of skin, exposing newer and healthier cells underneath.
