About
Chlorella-derived extracellular vesicles — a novel algal antioxidant active. Interesting science, but evidence is still early.
Chlorella Vulgaris Extracellular Vesicles are nano-scale lipid-bilayer vesicles isolated from cultured Chlorella vulgaris microalgae. Like other plant/algal EVs, they carry a cargo of polyphenols, chlorophyll-derived antioxidants, small peptides, lipids and small RNAs. In cosmetics they are marketed as a skin-conditioning antioxidant delivery system drawing on the established history of Chlorella extracts for skin benefits. Scientific case is intriguing but immature — most data is in vitro, translational studies are limited, and regulators (notably US FDA) have issued warnings about "exosome" marketing claims. Topical safety at cosmetic levels appears acceptable, but there is no CIR/SCCS specific evaluation, and particle size/cargo standardization varies between suppliers.
