Antioxidant Skin conditioning Anti-aging Brightening Elasticity support

Science

Mechanism of Action

Functions as a multi-pathway skin protector by inhibiting elastase enzymes to preserve elastin integrity, scavenging reactive oxygen species through phenolic compounds, and suppressing tyrosinase activity to regulate melanin production via downregulation of key melanogenic genes (MITF, TYR, TRP-1, TRP-2).
