What brands say it does
Fibroblast growth factors are signaling proteins that support cell growth and repair pathways. In cosmetics you may see them as sh-polypeptides or “FGF” complexes in barrier-repair and post-procedure products. Evidence is weaker than retinoids; they are niche premium actives, not drug-grade wound therapies.
Where you’ll find it
K-beauty repair ampoules, post-laser creams, and growth-factor serum lines—often alongside EGF.
