GOOD
Active Ingredient
Exosomes
INCI: EXOSOMES
Exosomes (CAS None) is a cosmetic active ingredient functioning as Nano-sized extracellular vesicles (30–150 nm) carrying proteins, lipids, and. EU Regulation 1223/2009 status: permitted. Industrial safety data is also available in the chemical safety database.
Function
Nano-sized extracellular vesicles (30–150 nm) carrying proteins, lipids, and nucleic acids (mRNA, miRNA, signalling molecules). In cosmetic context: exosomes from plant or stem cell sources deliver growth factors, peptides, and signalling RNA to target skin cells. Proposed mechanisms: stimulate fibroblast collagen and elastin production, modulate inflammatory signalling, support cellular repair and turnover, enhance epidermal-dermal communication.

US Notes
FDA guidance for exosomes as medical devices/biologics in clinical settings is evolving — cosmetic topical use at current concentrations is distinct from injectable exosome therapies. No specific cosmetic regulatory restrictions. Research is early-stage for cosmetic use. MoCRA safety substantiation required. Sourcing transparency (plant vs stem cell vs microbial origin) important for claims and safety dossier.
For full compliance data across multiple jurisdictions, use the Substance Compliance tool.
