Science
Mechanism of Action
This extract acts as a potent antioxidant, effectively neutralizing reactive oxygen species (ROS) and ABTS radicals to safeguard skin cells from oxidative stress and subsequent photoaging. Its anti-inflammatory capabilities stem from the inhibition of pro-inflammatory cytokines such as IL-6 and the suppression of signaling pathways like MAPK/AP-1. Furthermore, Euphrasia Officinalis Extract promotes skin regeneration and elasticity by accelerating cell turnover and stimulating collagen production. It provides moisturizing benefits by forming a protective layer that binds water molecules to the skin surface, minimizing transepidermal water loss. The extract also exhibits astringent properties to firm the skin, possesses antimicrobial activity against surface bacteria, and may contribute to skin brightening by inhibiting melanin synthesis. Its soothing properties, particularly around the eyes, help alleviate puffiness and dark circles through improved circulation.

Clinical Evidence

Key findings
- 01 In an in-vitro study using normal human dermal fibroblasts, a 95% ethanol extract of Euphrasia officinalis demonstrated significant protective effects against UVB-induced photoaging. At a concentration of 10 µg/mL, it decreased intracellular reactive oxygen species (ROS) production by 36.3%, and at 50 µg/mL, this reduction increased to 43.0%. The 50 µg/mL concentration also suppressed MMP-1 and MMP-3 expression by 49.9% and 41.1% respectively, and inhibited the pro-inflammatory cytokine IL-6 by 72.3%. Additionally, this extract enhanced cell migration and reduced apoptosis.
- 02 Research indicates that ethanol and ethyl acetate extracts of Euphrasia officinalis were non-toxic to human corneal cells at concentrations up to 125 µg/mL.
Transparency
Dusting Analysis
Euphrasia Officinalis Extract is considered an active ingredient due to demonstrated in-vitro efficacy, including significant antioxidant, anti-inflammatory, and photoaging protective effects at specific, measurable concentrations. Its multifaceted mechanisms of action support its genuine contribution to skin health.

Formulation
Stability
Aqueous extracts may experience color variations during storage, which can be dependent on temperature. The occurrence of cloudiness or precipitation is also possible, potentially requiring filtration for product clarity.
Conflicts
- Non-polar extraction solvents (e.g., heptane), which have been shown to produce extracts toxic to human corneal cells at concentrations exceeding 75 µg/mL and to limit cellular mitochondrial metabolism significantly at 25 µg/mL.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not published a specific safety assessment for Euphrasia Officinalis Extract. Safety profiles are highly dependent on the extraction solvent: ethanol and ethyl acetate extracts exhibited non-toxicity to human corneal cells at concentrations up to 125 µg/mL, while heptane extracts showed toxicity above 75 µg/mL. The FDA has not evaluated homeopathic products containing Euphrasia officinalis for safety or efficacy, and EWG Skin Deep® rates common concerns as 'LOW' but notes 'Limited Data'. A recommended use level for topical skincare is typically 5-10%.
