About

A recombinant protein derived from sturgeon Kit Ligand, produced in yeast and used for skin-conditioning purposes.

SR-Sturgeon Polypeptide-5 is a recombinant protein modeled on sturgeon (Acipenser schrenckii) Kit Ligand, produced in the yeast Pichia pastoris rather than E. coli. The use of a non-mammalian expression system reduces but does not eliminate concerns about non-human glycosylation patterns. The SCCS has not issued specific guidance on this ingredient, placing it in the general safe-for-cosmetics category with a moderate precaution level.
