Science
Mechanism of Action
This extract operates primarily as a skin-brightening agent by effectively inhibiting tyrosinase, a key enzyme in the melanogenesis process. Its efficacy stems from potent compounds like trans-resveratrol and its derivatives, including gnetin C and gnemonosides A and D. Furthermore, it delivers antioxidant benefits by neutralizing free radicals and may also offer anti-inflammatory effects, with potential to mitigate skin atrophy.

Key findings
- 01 A clinical study demonstrated a statistically significant average decrease of 3.50% in skin melanin index after 28 days of application of a Gnetum gnemon L. seed extract-loaded lipid particle gel. This efficacy was achieved without inducing skin irritation during the trial.

The Formula
Formulation
Stability
Resveratrol and its derivatives, the active components, exhibit inherent chemical instability and limited bioavailability, posing formulation challenges. Lipid particle technology has been successfully employed to enhance these properties. Extraction typically utilizes organic solvents such as ethanol, ethyl acetate, and methanol.
Safety
Safety Profile
While a 24-hour human single occlusive patch test indicated no skin irritation from an extract-loaded lipid particle gel, comprehensive dermal toxicity or established cosmetic regulatory statuses (CIR, SCCS, FDA) are not readily available. Safety for oral consumption in rats established a NOAEL of 1,000 mg/kg/day, but this does not directly translate to cosmetic dermal use.
