Science
Mechanism of Action
It induces contraction forces in dermal fibroblasts via stress fiber formation, promoting skin tightening and wrinkle reduction. Potent anti-inflammatory effects occur by inhibiting COX-1 and COX-2 activities and strengthening capillaries.

Key findings
- 01 Topical application of 3.0% significantly reduced wrinkle scores at the corners of the eyes and lower eyelids after 6-9 weeks by inducing fibroblast contraction.
Transparency
Dusting Analysis
Clinical efficacy for wrinkle reduction is demonstrated at 3.0%. Formulations containing less than 1.0% may be considered ineffective for primary anti-aging claims.
The Formula
Formulation
Stability
Saponins are heat-stable; aqueous solutions are stable across pH 3-11. A neutral to slightly acidic pH is preferred for optimal long-term cosmetic stability.
Conflicts
- Strong oxidizing agents
- High concentrations of divalent cations (Ca2+, Mg2+)
- Extremely alkaline environments (pH >11)
Safety
Safety Profile
While Aesculus turbinata bark specifically is unreviewed by CIR, related Aesculus hippocastanum is widely used and topical extracts are generally safe and non-irritating up to 3.0%.
