Science
Mechanism of Action
This extract operates through a tripartite pathway: avenanthramides suppress pro-inflammatory cytokine activity (specifically IL-8) and histamine release; beta-glucans create a breathable, film-forming shield to lock in moisture; and phenolic compounds provide robust antioxidant defense. Unique to the straw extract is its elevated silica concentration, which offers superior skin conditioning and structural support compared to grain-based extracts.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical evaluation at 3.0% demonstrated a measurable reduction in transepidermal water loss (TEWL) and significant enhancement of the lipid barrier.
- 02 Concentrations between 1.0% and 5.0% showed successful inhibition of NF-κB activation, effectively neutralizing redness and irritation triggers.
Transparency
Dusting Analysis
While often used at 'label claim' levels (under 0.5%), the bio-active benefits for barrier repair and anti-inflammation only become clinically significant at 1.0% or higher. Formulations featuring this ingredient at the end of the INCI list may lack sufficient concentration to impact skin health.
The Formula
Formulation
Stability
The extract remains stable under heat up to 85°C. To maintain clarity in transparent aqueous solutions, a slightly acidic pH (approx. 4.0) is recommended to prevent turbidity.
