Science
Mechanism of Action
This extract is rich in potent flavonoids and polyphenols, which confer strong antioxidant effects by neutralizing free radicals and demonstrating robust, concentration-dependent scavenging of oxygen radicals. Its anti-inflammatory action stems from inhibiting inflammatory mediators through heme oxygenase-1 upregulation, blocking the TAK1/AP-1 pathway, and reducing TNF-alpha synthesis via the c-Raf-MEK1/2-ERK1/2 phosphorylation pathway. For brightening, it effectively inhibits melanin production and decreases α-MSH-induced MITF and tyrosinase expression by activating extracellular signal-regulated kinase (ERK). Additionally, it helps regulate sebum production, minimize pore congestion, and delivers moisturizing and calming benefits.

Key findings
- 01 In an in vitro study, a 100 mg/mL concentration reduced tyrosinase activity by 35%, indicating significant potential for skin brightening.
- 02 A placebo-controlled clinical study on female subjects demonstrated a 44% decrease in melanin index value over 56 days when the extract was incorporated into a formulated cream.
- 03 Further in vitro research showed that it inhibited melanin production in B16F10 cells in a dose-dependent manner without causing cellular toxicity.
