Does Palmitoyl hexapeptide-12 work?
Not properly: lab tests on skin samples, with no published human trial.
The identifiable published work is a 2025 ex vivo study on excised human skin that tracked where the peptide goes and how it interacts with skin components, plus a 2018 industry safety review. No controlled trial in living people measuring wrinkles, firmness or hydration has been identified. That is laboratory evidence only. 12
No published controlled trial of palmitoyl hexapeptide-12 in living human skin has been identified in these sources. Such a trial would measure wrinkles, firmness or hydration. The human tissue data come from excised skin samples. Claims of visible results rest on manufacturer testing. That testing has not been published in a peer-reviewed journal. 1
