Keratinocyte growth factor
Establishes keratinocyte growth factor as a highly specific mitogen stimulating epithelial cell proliferation during tissue repair.
Recombinant sh-Polypeptide-3 (FGF-7 / KGF)
Recombinant KGF / FGF-7 (sh-Polypeptide-3) in a stabilizing aqueous suspension for barrier-support cosmetic formulas.*
Suspension stabilizers in the shipped bulk are processing aids and are not declared on the finished-product INCI when the material is used as directed. See SDS for details.
sh-Polypeptide-3 · CAS 126469-10-1 · ~19 kDa
Keratinocyte Growth Factor (KGF, FGF-7) signals keratinocyte proliferation and migration in published skin-science work. INCI lists the bioengineered form as sh-Polypeptide-3 for topical cosmetic use.*
We ship recombinant KGF in a stabilizing aqueous suspension at two strengths - standard 1X (0.016%) for typical cosmetic dilution workflows, or a 5X lab concentrate (0.08%) when you want five times the protein loading in the same pack. The suspension helps protect the active during refrigerated storage and reduce deterioration - see SDS for composition details.*
These attributes are assessments based on the ingredient deck and the supplier information available to us. They are not third-party certifications. If your finished product requires a specific certified status, please reach out and we’ll walk through what we can document.
Every lot is produced to order in our AI-powered robotic factory. Nothing sits on a warehouse shelf going stale - you get a date-of-manufacture-fresh batch every time.

Keratinocyte Growth Factor / FGF-7 (sh-Polypeptide-3) appears in keratinocyte biology and barrier-renewal literature relevant to cosmetic barrier-support serums. These are independent, third-party papers we link for formulators evaluating mechanism, tolerability, and published panel data. We did not conduct this research and do not guarantee replication in your finished formula.
Establishes keratinocyte growth factor as a highly specific mitogen stimulating epithelial cell proliferation during tissue repair.
Recombinant KGF accelerated re-epithelialization and increased epithelial thickness in a rabbit-ear wound model, targeting keratinocytes and other epithelial elements without stimulating fibroblasts or inflammatory cells.
Confirms through clinical review that topically applied growth factors including keratinocyte growth factor enhance extracellular matrix production and skin rejuvenation.

This is the bulk composition as it ships. Updates dynamically when you change the strength above. The active line shows the KGF loading at the selected concentration. Suspension stabilizers in the shipped bulk protect the active during storage and are not declared on the finished-product cosmetic INCI when the protein is reconstituted / diluted into your formula as directed. Full stabilizer identity and concentration are on the SDS.
SDS + TDS are issued per strength. Links swap when you change concentration above. COA is batch-specific and ships with the order.
