About

A stabilized synthetic tetrapeptide (SH-Type) used in advanced anti-aging skincare for its collagen-stimulating and skin-barrier strengthening properties.

SH-Tetrapeptide-39 is a synthesised peptide of the SH-class (palmitoyl-terminated type) designed for improved skin delivery and resistance to degradation. The SH designation refers to the N-terminal fatty acid (often stearyl or palmitoyl) modification that enhances skin penetration. Listed in EU CosIng without restrictions, these peptide types have been used safely in cosmetics for over a decade with no significant concerns reported.
