Science
Mechanism of Action
This extract modulates skin functions through several precise pathways. It significantly reduces hyperpigmentation by inhibiting tyrosinase, a key enzyme in melanin synthesis, and by activating the PLD1 signaling pathway, identified as a 'melanin braking system'. Abundant in bioactive flavonoids and polyphenols, it acts as a powerful antioxidant, scavenging free radicals to protect skin cells from oxidative stress and mitigate signs of premature aging like fine lines. Its anti-inflammatory capabilities diminish redness and swelling by suppressing pro-inflammatory cytokines. Furthermore, it exhibits antimicrobial activity against Propionibacterium acnes, the primary acne-causing bacterium, and inhibits 5α-reductase to help regulate sebum production. The extract also contributes to skin protection by inhibiting enzymes such as elastase and hyaluronidase.

Key findings
- 01 When incorporated into cosmetic compositions and applied directly to human skin, dry weight extract concentrations ranging from 0.0001% to 10% (w/v) were shown to improve skin elasticity and deliver anti-aging effects. A preferred concentration range was identified between 0.001% and 5% (w/v).
- 02 In laboratory studies using B16F10 melanoma cells, the extract demonstrated an inhibition of tyrosinase activity and a reduction in melanin content, indicating its potential as an effective agent for skin brightening and reducing hyperpigmentation.
- 03 Research highlighted the extract's significant antibacterial activity against Propionibacterium acnes. It also inhibited pro-inflammatory cytokines and suppressed 5α-reductase, collectively suggesting potent anti-acne properties by addressing both bacterial proliferation and sebum regulation.
