Science
Mechanism of Action
This extract functions via multiple biological pathways: it employs chlorogenic acids to chelate metallic ions (like iron) for cellular detoxification and utilizes flavonoids like hyperoside and rutin to neutralize reactive oxygen species. By protecting fibroblasts and keratinocytes, it preserves the integrity of Type I procollagen and mitigates inflammatory cascades triggered by urban pollutants.

Key findings
- 01 In vitro studies demonstrate significant antimicrobial activity against S. aureus and E. coli.
- 02 Research indicates topical delivery is optimized when paired with lipid carriers like shea butter, showing a 41.4-42.4% release rate of active substances.
Transparency
Dusting Analysis
Because there is no established regulatory maximum or standardized clinical 'gold standard' percentage for topical use, brands frequently include this extract at very low concentrations (under 0.1%) simply for label claims regarding 'natural' or 'soothing' benefits.
The Formula
Formulation
Stability
The extract shows increased antioxidant capacity in mildly alkaline environments (pH 8.1), though its color and stability may shift outside of neutral ranges. Stability is highest in water-based systems.
Synergies
- Shea Butter (enhances active release)
- UV Filters (complements photoprotection)
- Chelating Agents
Conflicts
- Beeswax (physically hinders the release of active phenolic compounds)
Safety
Safety Profile
Generally regarded as safe for topical use; oral studies show high tolerability, though specific dermal toxicity limits have not been formally established by the CIR.
