Science
Mechanism of Action
Phyllacantha Fibrosa Extract, derived from algae, is understood to contribute to skin conditioning through multiple mechanisms. It is associated with revitalizing and re-mineralizing effects, stimulation of blood circulation, and promotion of cell renewal. As a humectant, it is highly hygroscopic, efficiently drawing and retaining moisture to enhance skin smoothness and suppleness. The extract also provides beneficial components including lipids, proteins, vitamins, and minerals. Some algae extracts, in general, are noted for antibacterial properties.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded in 2019 that there was insufficient data to determine the safety of Phyllacantha Fibrosa Extract and related brown algae ingredients under intended cosmetic use. However, subsequent safety evaluations for concentrations below 10% indicated a low risk of phototoxicity and in vivo sensitization. A notable concern, as highlighted by EWG, involves potential contamination with heavy metals such as arsenic and lead, along with iodine. Achieving EWG VERIFIED status for products containing this ingredient necessitates robust substantiation to address these contamination risks and adhere to use restrictions.
