Pentapeptide-59 is a biomimetic (a synthetic ingredient that mimics the processes of a natural ingredient) peptide that contains the amino acids arginine, histidine, phenylalanine and valine. On skin, it has been shown to reduce signs of sensitization, including visibly reducing redness. It also helps skin become less sensitive by neutralizing signals in skin’s uppermost layers that would otherwise appear as signs of sensitivity.
In order to deliver this peptide to skin and keep it stable during use, it’s typically paired with emollient fatty acids such as shea butter or lecithin.
