Science
Mechanism of Action
It operates through a multi-pathway approach: inhibiting NF-κB and ERK signaling to reduce pro-inflammatory cytokines (TNF-α, IL-6) while downregulating matrix metalloproteinases (MMP-1, MMP-9) to prevent collagen breakdown. Additionally, its natural arbutin content provides mild enzymatic inhibition of tyrosinase for tone correction, while tannins offer astringent and antimicrobial benefits.

Key findings
- 01 Topical hydrogel application at 4 mg/cm² demonstrated a significant reduction in UVB-induced DNA damage (cyclobutane pyrimidine dimers) and epidermal thickening in vivo.
- 02 High-concentration formulations (up to 85%) have been dermatologically validated to reduce redness and irritation in sensitive skin populations without inducing comedogenicity.

Dusting Analysis
Due to its botanical nature, it is frequently included at negligible levels (0.1% or less) for marketing purposes. To achieve measurable biological effects on inflammation and DNA protection, concentrations between 2% and 5% are recommended.
The Formula
Formulation
Stability
Maintains peak stability in slightly acidic environments; typically processed in a water-glycerin carrier to preserve polyphenol bio-activity.
