Science
Mechanism of Action
This extract exerts its dermatological benefits through several pathways. It acts as a potent antioxidant by effectively scavenging free radicals like DPPH, ABTS, and NO, thereby protecting skin from oxidative stress. Its antimicrobial properties combat a spectrum of bacteria, including P. acnes, S. aureus, and S. epidermidis, as well as fungi such as Microsporum canis. Furthermore, it inhibits tyrosinase activity, which contributes to a more uniform skin tone, and provides a degree of UV protection primarily due to its Ethyl Methoxycinnamate content. For anti-aging, it significantly inhibits collagenase and elastase, enzymes responsible for breaking down dermal proteins.

The Formula
Formulation
Stability
While a specific optimal pH range for stability is not fully detailed, an ethanolic extract demonstrated good physicochemical properties and stability at a pH of 5.46 ± 0.01 within an oil-in-water cream. Its components are soluble in both polar (water, ethanol) and less polar (ethyl acetate, hexane) solvents, indicating versatile integration into water and oil-based formulations.
Safety
Safety Profile
Acute and subacute toxicity studies in rats, involving high oral doses of its ethanol extract (up to 5,000 mg/kg single dose and 1,000 mg/kg daily for 30 days), reported no significant toxicity, mortality, or skin irritation. It is considered safe for cosmetic formulations, with ethanol-based extracts specifically noted as safe for cosmeceutical anti-aging applications. SkinSAFE also classifies this ingredient as 'Irritant Free'.
