OTCA is a powerful antioxidant precursor that helps replenish the skin’s glutathione system, one of the body’s most important defenses against oxidative stress and environmental damage. By combating free radicals, this serum works to reduce early signs of aging, dullness, and fatigue caused by pollution, UV exposure, and stress.

The formula is further supported by Arginine, an amino acid that enhances repair, and Allantoin, known for its soothing and calming benefits. Hyaluronic Acid delivers layered hydration, leaving skin plump, protected, and refreshed.

This serum’s lightweight texture absorbs quickly, making it an ideal daily booster—used alone, before moisturizer, or added into an existing routine for amplified antioxidant protection.
