Science
Mechanism of Action
Functions through its rich polyphenolic profile to neutralize reactive oxygen species and prevent oxidative cellular damage. Inhibits tyrosinase enzyme activity to regulate melanin production and reduce hyperpigmentation. Protects structural proteins from enzymatic breakdown while stimulating fibroblast activity to enhance collagen and elastin synthesis, and modulates inflammatory pathways to calm skin irritation.

Key findings
- 01 Placebo-controlled study at 0.5-2.0% showed 34% increase in collagen synthesis and 35% wrinkle depth reduction
- 02 12-week trial at 2.0% demonstrated 41% reduction in brown spots with 9% improvement in sun protection
- 03 Efficacy trial at 0.5% achieved 20% reduction in water loss and 43% improvement in skin firmness
