The natural plant lysate contained in it can kill Staphylococcus aureus, keyococcus, and acne bacillus within 60 seconds without causing the microorganisms to produce antibodies. This product is non-irritating and non-allergenic to the skin, and can effectively prevent and treat acne and blackheads.
