Science
Mechanism of Action
This ingredient utilizes a complex profile of flavonoids and polyphenols, such as esculetin, to neutralize oxidative stress and suppress inflammatory cytokine production. It simultaneously acts as a natural humectant to improve cellular hydration and inhibits tyrosinase activity to help mitigate post-inflammatory hyperpigmentation.

Key findings
- 01 Concentrations as low as 3.0% in emulsions significantly protect against oxidative damage and maintain formula stability.
- 02 Applied at 100% as a primary distillate, it demonstrates immediate efficacy in reducing UVB-induced redness and restoring hydration to compromised skin barriers.

Dusting Analysis
While often used as a marketing 'hero' ingredient, clinical benefits for antioxidant protection begin at 3.0%. Formulas containing only trace amounts (under 0.5%) for label claims lack the concentration necessary to provide functional soothing or barrier support.
The Formula
Formulation
Stability
Highly photolabile; exposure to UV radiation causes phenolic degradation and color darkening. Formulations must be housed in light-blocking or opaque packaging.
Synergies
- Vitamin C
- Hyaluronic Acid
- Niacinamide
Conflicts
- Strong oxidizing agents
- Highly alkaline environments (pH > 7.0)
Safety
