Science
Mechanism of Action
It functions through a dual-action pathway: providing antioxidant defense via soluble phenols and flavonoids while utilizing natural organic acids to catalyze cellular turnover. Its astringent properties modulate surface sebum, while its chemical composition inhibits lipid peroxidation to protect the skin barrier from environmental degradation.
Research
Clinical Evidence
Medium confidenceN/A
Key findings
- 01 Ethanol extraction yields the highest bioactive profile, reaching 7.83 mg of total flavonoids per gram of dry extract.
- 02 In vitro testing demonstrated an 86.9% inhibition rate of linoleic acid oxidation, confirming high antioxidant efficacy.
Transparency
Dusting Analysis
Because it is often used as a fragrance component or natural 'story' ingredient, it is frequently included at concentrations below the threshold for clinical exfoliation or antioxidant protection.
The Formula
Formulation
Stability
Highly stable within a slightly acidic to neutral range (pH 4.0-6.5). It is water-soluble but insoluble in lipid-based carriers.
Synergies
- Ascorbic Acid
- Glycerin
- Niacinamide
Conflicts
- Furocoumarin-contributing botanicals
- High-intensity UV sensitizers
Safety
Safety Profile
Safety is contingent on the 5-MOP (5-methoxypsoralen) content, which must not exceed 15 ppm in leave-on formulations to prevent photosensitivity. EU regulations strictly limit furocoumarin content to below 1 mg/kg for sun-exposed products.
