Science
Mechanism of Action
This complex operates through several biochemical pathways: it modulates sebaceous gland activity by inhibiting 5-alpha-reductase to reduce oil production, while its high concentration of ferulic acid and alkylresorcinols provides robust antioxidant protection. Additionally, it demonstrates targeted antimicrobial action against Cutibacterium acnes and reinforces the lipid matrix to prevent transepidermal water loss.

Key findings
- 01 A 4-week clinical assessment of a 3% concentration showed a significant reduction in facial sebum levels and a measurable improvement in barrier function via lipid peroxidation inhibition.
- 02 In-vitro and in-vivo testing at 2% demonstrated effective antimicrobial activity against C. acnes, leading to a visible reduction in inflammatory acne lesions.

Dusting Analysis
As a botanical complex, this ingredient is frequently included in formulas at symbolic levels (0.1% or less) for marketing claims. However, clinical data suggests a therapeutic threshold of at least 2% is required to achieve antimicrobial benefits, and 3% for significant sebum regulation.
The Formula
Formulation
Stability
Highly sensitive to thermal degradation; must be incorporated during the cooling phase (below 40°C) to preserve polyphenol integrity. The extract is also UV-sensitive and should be stored in opaque packaging.
Synergies
- Niacinamide
- Hyaluronic Acid
- Zinc PCA
Conflicts
- Strong oxidizing agents
- High electrolyte concentrations
Safety
Safety Profile
Both parent botanicals have been cleared by the CIR. While generally non-sensitizing, a patch test is recommended for individuals with severe wheat allergies due to the Triticum vulgare component.
