Science
Mechanism of Action
Functions as a potent free radical scavenger while simultaneously inhibiting Matrix Metalloproteinase-1 (MMP-1) expression triggered by UV radiation and environmental pollutants. Stimulates Type I procollagen synthesis for structural support and suppresses tyrosinase activity to reduce melanogenesis and promote skin brightening.
