sh-Polypeptide-3
Synthetic recombinant peptide (former rh-Oligopeptide-5), identified as an analog of human keratinocyte growth factor/FGF-7. In cosmetics it is used primarily as a skin-conditioning, anti-aging, and regeneration-support ingredient. Public ingredient databases describe it as synthetic and commonly used in anti-aging products; the peptide is also associated with epithelial repair and keratinocyte proliferation.

Risks & Warnings
Overall low irritation potential, but human cosmetic safety data are limited in public sources. As a growth-factor-like peptide, the main concerns are formulation stability, contamination/quality control, and the fact that long-term pregnancy/lactation safety data are insufficient. In highly sensitive users, any peptide-containing serum can still cause mild stinging from the full formula rather than the peptide itself.
