Science
Mechanism of Action
This ingredient functions by utilizing the inherent protective compounds within strawberry callus. It contains polyphenols, condensed tannins, pentacyclic triterpenes, and anthocyanins, which collectively exhibit significant antioxidant and anti-inflammatory properties. These components are hypothesized to safeguard human dermal fibroblasts against UV-A radiation, thereby improving cellular viability and mitigating DNA damage, supporting the skin's natural defense mechanisms.

Key findings
- 01 A methanol extract of Fragaria × ananassa, at concentrations of 0.05, 0.25, and 0.5 mg/mL, demonstrated photoprotective activity against UV-A radiation in human dermal fibroblasts, enhancing cellular viability and reducing DNA damage. It is important to note this study was conducted on an extract, not directly on the callus powder.
Transparency
Dusting Analysis
The available research data does not indicate that Fragaria Ananassa Callus Powder is commonly used in formulations with 'dusting' claims, where negligible amounts are included for marketing without significant efficacy.

Stability
As a plant-derived powder, Fragaria Ananassa Callus Powder may clump when exposed to heat or moisture. Optimal preservation is achieved by storing in a cool, dry place, away from direct sunlight, with refrigeration suggested. Formulations containing strawberry derivatives typically show physical stability within a pH range of 4.5 to 6.5.
Safety
Safety Profile
Fragaria Ananassa Callus Powder has not undergone formal review by the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS). Its status with the FDA for cosmetic use is not explicitly defined. Paula's Choice currently lists it as 'Not rated,' a 'New ingredient,' and with 'No known benefits' in their database.

Verdict
While Fragaria Ananassa Callus Powder offers theoretical benefits through its antioxidant properties, direct clinical evidence specifically for the powder, as well as comprehensive safety assessments, are currently insufficient.
