Peptide Comparison

FGF-1 vs KGF-1

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

FGF-1: Binds all four FGFR subtypes (broadest binding of FGF family). Activates MAPK and PI3K downstream pathways. Promotes fibroblast proliferation, angiogenesis, and hair follicle cycling into anagen phase. 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.
