Science
Mechanism of Action
Its primary actions stem from triterpene saponin 'escin' and flavonoids, which reduce capillary permeability by inhibiting enzyme degradation of vessel walls. This improves microcirculation, decreases fluid leakage (anti-edema), and provides robust free radical scavenging against ROS and RNS.

Key findings
- 01 Clinical studies at 1.0%-3.0% confirm efficacy in reducing inflammation, strengthening capillaries, and providing antioxidant protection.
- 02 Concentrations from 0.1%-2.0% are effective for reducing eye puffiness and dark circles, while 2.0% significantly improved redness in rosacea-prone skin.
Transparency
Dusting Analysis
Efficacy is observed within the 0.1%-3.0% range. Concentrations above 3.0% are generally avoided in leave-on products due to potential irritation from native esculin, rather than a lack of efficacy.
The Formula
Formulation
Stability
Stable in aqueous solutions and O/W emulsions. To protect bioactive saponins, it should be added during the cooling phase below 40°C.
Conflicts
- Strong oxidizing agents
- Highly alkaline environments (pH > 7.5)
Safety
Safety Profile
Generally recognized as safe for topical use when purified to remove toxic esculin. Unprocessed material or high concentrations on compromised skin can be problematic.
