Oligopeptide-1, also known as EGF (epidermal growth factor), is a synthetic peptide used in skincare to support cell turnover, signaling, and skin repair. It is incorporated into anti-aging and barrier-restoration formulations for its potential to stimulate fibroblast activity and collagen production.
