Science
Mechanism of Action
The extract functions via a high concentration of specific flavonoids, including oleuropein, ligustroside, and quercetin. These compounds act as potent antioxidants that neutralize reactive oxygen species (ROS) while simultaneously inhibiting four critical enzymes: collagenase and elastase (to prevent ECM breakdown), tyrosinase (to modulate melanogenesis), and hyaluronidase (to downregulate pro-inflammatory responses).

Clinical Evidence

Key findings
- 01 In vitro analysis demonstrated that a 200 µg/mL concentration achieved a 96.26% inhibition rate of collagenase, significantly preserving skin elasticity.
- 02 Research indicates a 95% inhibition of lipid peroxidation at 150 µg/mL, confirming its status as a high-tier antioxidant.
- 03 Studies show an 88.70% inhibition of hyaluronidase at 0.02%, highlighting its efficacy in reducing chemical triggers of skin sensitivity.
Transparency
Dusting Analysis
Because this extract shows remarkable enzymatic inhibition at very low concentrations (approx. 200 µg/mL), it is frequently included in 'botanical' marketing stories at trace amounts (below 0.01%) that fail to trigger the measured anti-aging benefits.
The Formula
Formulation
Stability
Contains both polar glycosides and non-polar aglycones. For maximum stability of flavonoid content, formulations should maintain a slightly acidic pH and avoid exposure to air.
Synergies
- Vitamin C (stabilization)
- Hyaluronic Acid (complementary hydration)
- Niacinamide (enhanced brightening)
Conflicts
- Strong oxidizing agents
- Ferric ions (potential for chelation-induced discoloration)
- Strongly alkaline environments (pH > 8.0)
Safety
Safety Profile
Considered non-cytotoxic to human fibroblasts. It has a documented history of use in traditional medicinal applications and modern East Asian dermo-cosmetics.
