Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A synthetic four-amino-acid peptide marketed as a skin-conditioning signal peptide. Like most modern designer peptides, used at trace levels with limited public safety literature.
Tetrapeptide-124 is a chemically synthesized four-amino-acid peptide developed for cosmetic skin-conditioning applications. Designer peptides in this naming series are typically supplied as dilute solutions and used at parts-per-million concentrations in serums and creams. The class as a whole is considered low-irritation and low-systemic-risk because the peptide payload is small and unstable on the skin surface, but Tetrapeptide-124 itself does not yet have published CIR or SCCS reviews, and supplier-independent efficacy data is limited. INCI is listed in EU CosIng. Default tier: yellow with low evidence.
