What does Undecylenoyl Phenylalanine do in skincare?
It is used mainly as a skin-conditioning ingredient with a reputation for helping the appearance of an even skin tone. It is a compound made by combining undecylenic acid with the amino acid phenylalanine. In formulas it is typically positioned as a brightening-support ingredient rather than a UV filter.
