Science
Mechanism of Action
This extract works by modulating key inflammatory pathways, demonstrating dose-dependent inhibition of mediators like prostaglandin E2 (PGE2) and histamine in immune cells. Its antioxidant capacity, attributed to phytochemicals such as flavonoids, helps combat oxidative stress. Furthermore, it exhibits direct antibacterial and antifungal actions, contributing to skin purification and wound repair. The extract is also noted for its ability to promote tissue regeneration and enhance skin elasticity and moisture levels.

Dusting Analysis
As a stem extract, this ingredient is not typically associated with dusting. While the fibrous material of the luffa fruit can be abrasive, this concern does not apply to the extract form.
The Formula
Formulation
Stability
The extract contains a diverse array of phytochemicals, including phenolics (water-soluble), flavonoids (ethanol-soluble), and oleanolic acid, carotenoids, and chlorophylls (ethyl acetate-soluble), suggesting complex solubility characteristics. Specific optimal pH ranges for cosmetic formulation stability are not documented.
Safety
Safety Profile
Generally considered non-toxic for topical use. Dermal application studies in rats indicated no visible irritation (redness or edema), suggesting a low risk of sensitization. Concerns regarding abrasiveness apply to the coarse fibrous fruit, not the purified stem extract. The whole luffa fruit, when used as a sponge, carries a risk of microbial contamination if not dried properly.
