Palmitoyl Dipeptide-5 Diaminohydroxybutyrate
Explained
This ingredient is a synthetic lipopeptide and is technically a tripeptide. It's made by connecting palmitic acid to a short amino acid chain so it can move through the skin's fatty outer layers more easily.
It is most often found in formulations with its sibling, Palmitoyl Dipeptide-5 Diaminobutyroyl Hydroxythreonine in a trade blend called Syn-Tacks.
The combination of the two peptides target the dermal-epidermal junction (DEJ), or the mesh that connects your epidermis to your dermis. Your DEJ naturally thins with age and exposure.
Peer-reviewed research on DEJ targeted peptides and manufacturer data suggests the pair tells your skin cells to produce more structural proteins that hold the DEJ together.
In studies, this translates to firmer skin and a bump in skin thickness via ultrasound.
