Dipeptide-2 is a small, less complex synthetic peptide made up of the amino acids tryptophan and valine. Studies from one ingredient supplier indicate that this peptide as part of a blend may improve fluid drainage in the eye area, thus reducing the look of puffy eyes; however, as this is being written in late 2019, this claim isn’t supported by independent research.

Generally, dipeptide-2 is considered a skin conditioning ingredient whose smaller size allows it to easily penetrate skin’s uppermost layers where it can assist with skin renewal and replenishment.
