Science
Mechanism of Action
Crassula argentea leaf extract functions through its rich profile of phytochemicals, including flavonoids, triterpenes, tannins, and phenolic compounds. Its antioxidant action is attributed to the neutralization of free radicals, helping to mitigate oxidative stress. The extract exhibits potential anti-inflammatory effects by modulating cellular responses, and antimicrobial activity against various bacteria such as Escherichia coli, Pseudomonas, and Klebsiella sp. Furthermore, it supports skin regeneration and repair by potentially enhancing granulation tissue formation, epidermal regeneration, angiogenesis, and collagen production, while contributing to skin hydration through the plant's natural water-retaining properties.

Safety
Safety Profile
There is currently no specific CIR, SCCS, or FDA safety assessment available for Crassula argentea (Crassula ovata) leaf extract in cosmetic applications. Comprehensive toxicological data for the processed extract is lacking. While some traditional claims suggest mild toxicity from raw plant sap, these remain unproven and are distinct from the safety profile of a purified cosmetic extract.
