About

A recombinant fusion peptide produced in Chinese hamster ovary (CHO) cells, combining two human skin peptides with a favorable safety profile.

A recombinant peptide produced in CHO (Chinese hamster ovary) mammalian cells, combining sh-Polypeptide-143 and sh-Polypeptide-144 sequences. CHO cell expression is a well-established platform for therapeutic protein production, but introduces mammalian host cell protein considerations under EU Cosmetics Regulation. No EU restrictions listed; safety is dependent on purification standards. Score slightly lower than E. coli-produced peptides due to mammalian origin.
