Peptides are two or more amino acids connected together and are a component of proteins. Peptides are mainly divided into three categories: signal peptides, carrier peptides, and peptides that inhibit neural signals. Signal peptides, such as palmitoyl tripeptide-1, act as messengers for cells, triggering collagen synthesis and increasing skin firmness. Palmitoyl tripeptide-1 is a small three amino acid signaling peptide with an amino acid sequence of glycine histidine lysine (GHK). GHK adheres to palmitic acid (a fatty acid) to increase its skin permeability and oil solubility.
