Science
Mechanism of Action
Operates through a complex network of phenolic compounds, including rutin and ellagic acid, which neutralize reactive oxygen species and inhibit matrix metalloproteinases (MMPs) to prevent collagen breakdown. It further stabilizes the skin barrier by modulating epidermal protein synthesis and employs 'quorum quenching' to prevent Staphylococcus aureus virulence without harming beneficial microflora.
Research
Clinical Evidence
High confidence0.025%
Key findings
- 01 Demonstrated a 66.4% reduction in UV-induced DNA damage in human keratinocytes at a concentration of 0.1 µg/mL.
- 02 In vivo testing at 0.025% confirmed significant skin hydration maintenance for over 4 hours post-application.
- 03 Clinical evaluation of a 2.0% blend (providing 0.01-0.03% active extract) showed high efficacy in soothing inflammation and reinforcing barrier function.
Transparency
Dusting Analysis
Because this extract shows measurable biological activity at extremely low thresholds (0.01% for barrier support), it is difficult to classify as 'dusted' unless used in trace amounts purely for label claims. However, clinical benefits for anti-aging and DNA protection are maximized near the 0.1% to 1.0% range.
The Formula
Formulation
Stability
Highly pH-dependent; antioxidant capacity significantly diminishes at a neutral pH of 7.1. Stability is best maintained in glyceric carriers and must be protected from temperatures exceeding 40°C.
Synergies
- Glycerin
- UV filters
- Barrier-repairing lipids
Conflicts
- Alkaline formulations (pH > 7.0)
- High-heat manufacturing processes
Safety
Safety Profile
Standard cosmetic usage between 0.1% and 1.0% is categorized as safe based on clinical patch testing.
