Science
Mechanism of Action
This extract functions primarily as a potent antioxidant, utilizing its high content of vitamins C and E, polyphenols, and flavonoids to neutralize free radicals, thereby mitigating oxidative stress that leads to premature aging and environmental damage. It enhances skin hydration by acting as a humectant, drawing and retaining moisture to improve plumpness and suppleness. The ingredient exhibits significant anti-inflammatory capabilities by reducing redness and soothing irritation, partly through modulating gene expression and decreasing the activation of IL-1 receptor accessory proteins. Furthermore, it stimulates collagen production and extracellular matrix (ECM) synthesis, vital for improving skin elasticity, firmness, and overall repair, while actively inhibiting matrix metalloproteinase 2 (MMP-2) and matrix metalloproteinase 9 (MMP-9) expression, which are enzymes known to degrade collagen and elastin.

Key findings
- 01 In vitro studies demonstrated that young barley extracts at concentrations of 25, 50, and 100 µg/mL significantly enhanced the survival rate and accelerated migration of human skin fibroblasts exposed to UVB radiation. These extracts also stimulated DNA biosynthesis and effectively inhibited the expression of matrix metalloproteinase 2 (MMP-2) and matrix metalloproteinase 9 (MMP-9).
- 02 Murine B16F10 melanoma cells showed observed anti-melanogenic effects when treated with Hordeum vulgare L. barley sprout extract.

Conflicts
- Individuals with gluten sensitivity should exercise caution, as barley and its derivatives naturally contain gluten.
Safety
Safety Profile
The CIR Expert Panel found insufficient data to definitively determine the safety of Hordeum Vulgare Sprout Extract under cosmetic conditions, recommending 28-day dermal toxicity data. However, related ingredients such as Hordeum Vulgare Extract have been reported safe for use in leave-on products at concentrations up to 1.5%, with a 0.005% concentration in an eye cream showing no irritation for sensitive eyes. Malt extract, a broader barley derivative, is generally recognized as safe (GRAS) by the US FDA for animal feeds. A key consideration is the presence of gluten, which may affect individuals with gluten sensitivity.
