Science
Mechanism of Action
This botanical water, sourced from Eyebright, acts through several pathways to benefit the skin. It exhibits anti-inflammatory effects by inhibiting key mediators and stabilizing mast cells, primarily due to flavonoids and tannins. As an antioxidant, its polyphenolic compounds and quercetin effectively neutralize free radicals, shielding cells from oxidative damage. Tannins also contribute an astringent action. For hydration, it forms a protective layer, reducing transepidermal water loss and enhancing elasticity. Furthermore, it aids skin recovery by promoting cell regeneration, stimulating collagen, and protecting new cells. Bioactive compounds confer antimicrobial properties, and it offers protection against UVB-induced photoaging by mitigating oxidative stress, inflammation, and cellular apoptosis.

The Formula
Formulation
Stability
As an aqueous distillate (hydrosol), this ingredient is inherently water-soluble. It typically presents as a medium to dark amber liquid with a characteristic natural odor. Due to its aqueous and natural composition, appropriate preservation strategies are essential to ensure microbial stability within cosmetic formulations.
Safety
Safety Profile
No dedicated CIR (Cosmetic Ingredient Review) or SCCS (Scientific Committee on Consumer Safety) safety assessment for Euphrasia Officinalis Flower/Leaf/Stem Water is available. However, its extensive traditional topical use for various eye ailments suggests a generally favorable safety profile. In vitro studies on human corneal cells found that ethanol and ethyl acetate extracts were non-toxic at concentrations up to 125 μg/mL, though heptane extracts exhibited toxicity at 25 μg/mL. Acute oral toxicity studies in rats with aqueous Eyebright extract showed no signs of toxicity at doses up to 6 g/kg. The EWG Skin Deep database rates 'Euphrasia Officinalis Extract' with low concern for cancer, allergies, immunotoxicity, and developmental/reproductive toxicity.
