Science
Mechanism of Action
Functions through multiple pathways including stimulation of dermal fibroblast proliferation and migration to facilitate collagen deposition and re-epithelialization. The extract's rich profile of phenylethanoid glycosides (particularly verbascoside), flavonoids (luteolin, quercetin), and iridoids provides broad-spectrum antioxidant protection by neutralizing reactive oxygen species and preventing DNA alkylation damage. Additionally modulates inflammatory response by regulating key markers including IL-6 and TNF-α.
Research
Clinical Evidence
High confidence0.005%
Key findings
- 01 Significantly enhanced human dermal fibroblast proliferation and migration at 12.5-50 µg/mL concentrations, critical for tissue repair processes
- 02 Exhibited potent free radical scavenging activity below 10 µg/mL, providing cellular protection from oxidative stress

Dusting Analysis
Given demonstrated efficacy at concentrations below 0.001%, any formulation containing less than 0.0005% should be considered potentially ineffective dusting rather than therapeutic dosing.
The Formula
Formulation
Stability
Maintains optimal stability within slightly acidic pH range that complements skin's natural acid mantle. Polyphenolic compounds are vulnerable to degradation from excessive heat and light exposure, requiring protective packaging or encapsulation technology.
Synergies
- Other antioxidants
- Wound healing peptides
- Hyaluronic acid
Conflicts
- Strong oxidizing agents
- High pH environments above 7.0
Safety
Safety Profile
Toxicological studies in animal models support topical safety even at concentrations exceeding typical commercial usage levels. In vitro cytotoxicity observed only at concentrations above 50 µg/mL, well beyond effective therapeutic range.
