Acetyl Tetrapeptide-2
Acetyl Tetrapeptide-2Active
A synthetic acetylated tetrapeptide derived from a thymic peptide sequence, supplied as a fibroblast-signaling active.
What it does
Acetyl Tetrapeptide-2 is a four-amino-acid synthetic peptide derived from a thymic peptide sequence, capped with an acetyl group at the N-terminus to improve stability. The peptide-house literature positions it as engaging fibroblast activity and skin-renewal pathways through an immune-signaling mechanism. In a formula it is included for that proposed mechanism. Independent peer-reviewed human topical RCTs with cosmetic endpoints for Acetyl Tetrapeptide-2 specifically are limited.
