What it is
sh-Polypeptide-10 is a synthetic human-identical polypeptide produced through recombinant biotechnology, with the sh prefix denoting a synthetic version of a human protein sequence. In cosmetics it is used as a skin-conditioning ingredient and is commonly marketed in the context of growth-factor-style formulations. It is a supporting peptide and does not act as a UV filter.
Safety & warnings
Bioengineered polypeptides of this type are generally well tolerated at cosmetic use levels. Irritation or sensitization is uncommon but possible, and accompanying stabilizers or preservatives in the raw material may contribute to reactions.
Origin & sourcing
Synthetic; manufactured by recombinant biotechnology (typically microbial fermentation) to produce a peptide matching a human protein sequence, not extracted from human tissue.
Questions everyone asks
Where does sh-Polypeptide-10 come from?
It is made through biotechnology, typically microbial fermentation, to produce a peptide that matches a human protein sequence. It is not derived from human tissue.
Does it provide sun protection?
No. It is a skin-conditioning peptide with no UV-filtering ability and serves as a supporting ingredient in the formula.
