Science
Mechanism of Action
This extract operates through multiple pathways to support skin health. Rich in antioxidants, vitamins, and minerals, including zinc, copper, and selenium, it provides essential nourishment and strengthens the skin's defense against environmental aggressors like pollution and UV rays. It actively modulates gene expression, notably by reducing the expression of accessory proteins that activate the IL-1 receptor, thereby lessening inflammatory responses and soothing irritation. Furthermore, it stimulates extracellular matrix (ECM) production, contributing to skin repair and offering anti-aging benefits by improving elasticity and targeting the appearance of fine lines and wrinkles.

Safety
Safety Profile
The CIR Expert Panel concluded that available data are insufficient to determine the safety of Hordeum Vulgare Leaf Extract for intended cosmetic uses, necessitating additional dermal toxicity, irritation, and sensitization data at maximum concentrations. General concerns exist regarding pesticide residues, heavy metals, and other botanical contaminants, emphasizing the need for robust manufacturing practices. While a product containing 0.005% Hordeum Vulgare Extract was found to be non-irritating in patch tests and non-ophthalmologic irritant, it's noted that barley and its derivatives are a source of gluten. The highest reported use for a general Hordeum Vulgare Extract (not specifically leaf) is 1.5% in leave-on body and hand products.
