Peptide Comparison

EGF vs KGF-1

Q: What is the difference between EGF and KGF-1?

EGF: Binds EGFR (EGF receptor / ErbB1), activating RAS/MAPK and PI3K/Akt signaling cascades. KGF-1: Binds FGFR2b (the KGF receptor), which is exclusively expressed on epithelial cells — providing tissue-specific action without mesenchymal effects.

Both are Skin & Cosmetic peptides.
