Science
Mechanism of Action
The extract operates through a dual-action pathway: flavonoids (like isoorientin) and avenacosides inhibit the production of pro-inflammatory cytokines such as IL-2 and enzymes like COX-2. Simultaneously, its high protein content forms a breathable, imperceptible film on the stratum corneum, providing immediate structural support and preventing transepidermal water loss.

Key findings
- 01 A 3% concentration demonstrated a 30.05% reduction in skin oil content over 28 days, alongside significant moisturizing benefits.
- 02 Concentrations between 2.5% and 7.5% significantly enhanced skin hydration levels and reduced TEWL after 4 weeks of consistent application.
- 03 In vitro data shows that concentrations of 10-30 µg/mL can inhibit keratinocyte inflammation markers by up to 57%.
Transparency
Dusting Analysis
While often listed for marketing purposes due to its 'soothing' reputation, many mass-market formulas include it at symbolic levels (<0.5%). To achieve the clinically validated 30% sebum reduction and barrier repair, concentrations of 2.5% to 3.0% are required.
The Formula
Formulation
Stability
Highly stable in standard emulsions; however, the bioactive polyphenols are thermolabile and should not be exposed to temperatures exceeding 80°C during the manufacturing process.
Synergies
- Hyaluronic Acid
- Ceramides
- Alpha Hydroxy Acids (AHAs)
Conflicts
- None known
