Science
Mechanism of Action
Operating as a potent antioxidant, O-Tolyl Biguanide actively scavenges and neutralizes free radicals—unstable molecules known to induce cellular damage. By combating this oxidative stress, it effectively protects skin cells from environmental pollutants and UV exposure, thereby supporting the preservation of skin integrity and delaying visible signs of premature aging.
