Science
Mechanism of Action
This extract exerts its dermatological efficacy through a complex blend of bioactive compounds, including flavonoids, phenolic acids, ellagitannins, proanthocyanidins, anthocyanins, and vitamin C. It actively functions as a robust antioxidant, mitigating oxidative stress and protecting the skin from environmental aggressors. Its antimelanogenic effect is achieved by inhibiting tyrosinase, a key enzyme in melanin synthesis, thereby promoting a more even and luminous skin tone. Additionally, it offers antiseptic, emollient, and anti-inflammatory properties. The polyphenols within the extract enhance microcirculation, optimizing cellular oxygenation, while tannins impart an astringent action, refining skin texture and reducing pore visibility. Furthermore, saccharides and ellagic acid contribute to skin hydration and soothing.

Key findings
- 01 A 2% (w/w) F. vesca extract-based hydrogel demonstrated excellent cutaneous compatibility, user acceptability, and significant antioxidant efficacy, affirming its suitability for topical formulations.
- 02 In vitro analyses revealed that strawberry extracts, at concentrations of 25 µg/mL, conferred notable photoprotection to human dermal fibroblasts, exhibiting a dose-dependent increase in cell viability.
- 03 The F. vesca extract effectively inhibited tyrosinase activity with an IC50 of 238.10 ± 15.51 µg/mL, indicating promising antimelanogenic potential for skin brightening.

Dusting Analysis
While a powder form of Fragaria Vesca Leaf Extract is suggested for aqueous formulations, the robust mechanistic data and demonstrated clinical efficacy at specific concentrations indicate a functional role for the ingredient, not merely a 'dusting' application for marketing.
The Formula
Formulation
Stability
Hydrogels containing Fragaria vesca extract exhibit physicochemical stability under varied storage conditions. However, direct exposure to sunlight can lead to brownish-green discoloration through oxidation. Storage at 40 °C may result in darkening and increased fluidity. Optimal stability for products is generally observed within a pH range of 4.5 to 6.5.
Safety
Safety Profile
Fragaria vesca extract is recognized as a natural ingredient with a generally safe profile for cosmetic applications at typical concentrations, demonstrating low irritation and sensitization potential. It is non-phototoxic, making it suitable for use during daytime. In vivo studies, including patch tests and Human Repeat Insult Patch Testing (HRIPT), have confirmed excellent cutaneous compatibility for hydrogels incorporating F. vesca extract. The F. vesca plant itself is classified as safe (Class 1) by a European Union herbal monograph, with no clinically relevant interactions expected (Class A).
