Science
Mechanism of Action
Creates a smooth micro-crystalline film on skin that prevents transepidermal water loss while delivering astringent benefits through its high tannin content. The flavonoid compounds provide antioxidant protection against oxidative stress, while the occlusive properties help maintain skin barrier integrity and hydration levels.
Research
Clinical Evidence
Medium confidence3%
Key findings
- 01 12-week study with 3% concentration showed 30.3% reduction in sebum, 55% improvement in skin roughness, 23.9% wrinkle reduction, and 32.2% increase in hydration
- 02 In vitro studies at 0.02-2 mg/mL demonstrated significant DPPH and ABTS radical scavenging activity plus antimicrobial effects against S. aureus and S. epidermis

Dusting Analysis
Typically used at effective concentrations of 1-5% in formulations, making dusting unlikely due to meaningful usage levels required for clinical benefits.
The Formula
Formulation
Stability
Exhibits excellent stability in anhydrous formulations. In water-based systems, complexing with lecithin or incorporating into wax blends enhances stability. Tannin content may cause color changes when exposed to light or metal ions.
Synergies
- lecithin
- jojoba oil
- mimosa wax
- sunflower oil
Conflicts
- strong oxidizing agents
- iron salts
- alkaline pH environments above 7.0
