Palmitoyltetrapeptide-20 (TFA)

Palmitoyl tetrapeptide-20 (PTP20) TFA is a biomimetic peptide agonist of α-MSH. Palmitoyl tetrapeptide-20 TFA promotes hair pigmentation and delays hair graying by activating the MC1-R pathway (AC50: 0.16 nM), enhancing catalase activity to reduce H2O2 accumulation, and upregulating SIRT1 activity. Palmitoyl tetrapeptide-20 TFA can be used in research on preventing hair loss and improving hair graying[1].
