Undecylenoyl Phenylalanine
What is Undecylenoyl Phenylalanine?
Undecylenoyl phenylalanine is a synthetic lipoamino acid, formed by linking undecylenic acid—a fatty acid derivative—with phenylalanine, an essential amino acid. Primarily used in brightening and anti-aging cosmetic products like serums and creams, it functions as a targeted modulator of pigmentation. By acting as a competitive antagonist to alpha-melanocyte-stimulating hormone (alpha-MSH) at melanocortin-1 receptors on melanocytes, it inhibits the signaling pathway that triggers melanin synthesis, promoting a more uniform complexion over time. Additionally, its emollient properties contribute to skin conditioning, enhancing softness and flexibility without clogging pores. This dual action makes it suitable for formulations addressing uneven tone, often incorporated at low concentrations in leave-on products for daily use.
