Undecylenoyl Phenylalanine is a lipoamino acid derived from undecylenic acid (a fatty acid obtained from castor oil) and phenylalanine (an essential aromatic amino acid). It belongs to the class of N-acyl amino acid derivatives and is primarily used in cosmetic and personal care formulations for its skin-brightening and pigmentation-regulating properties.

Undecylenoyl Phenylalanine functions as a melanin synthesis inhibitor by acting as a competitive inhibitor of tyrosinase, the key enzyme responsible for melanin production. By binding to the tyrosinase active site, it reduces the conversion of tyrosine to DOPA and subsequent melanin formation, thereby helping to lighten hyperpigmentation, age spots, and uneven skin tone.

In addition to its depigmenting effects, the phenylalanine moiety provides moisturizing and skin-conditioning benefits, while the undecylenic acid chain enhances skin penetration and bioavailability. This dual functionality makes Undecylenoyl Phenylalanine a valuable ingredient in brightening serums, anti-spot treatments, and overall skin tone evening formulations.
