Hypotaurine is known as a scavenger of singlet oxygen. It is proven to be 2 times more effective than tocopherol acetate, which is known as a conventional scavenger of singlet oxygen. HYPOTAURINE or 2-Aminoethanesulfinic acid (H2N-CH2CH2-SO2H) effectively scavenges singlet oxygen which accelerates oxidation in the skin, causing skin aging. It also has high humectancy.
