Alanyl Glutamine
What is Alanyl Glutamine?
Alanyl Glutamine is a synthetic dipeptide created by bonding the amino acids alanine and glutamine. It falls under skin conditioning agents in cosmetics, primarily functioning as a humectant and emollient. As a humectant, it pulls water from the environment into the skin's upper layers, promoting hydration and helping to keep the stratum corneum plump. Its emollient action softens skin by filling microscopic gaps on the surface, enhancing smoothness and reducing dryness. Typically incorporated into moisturizers, lotions, serums, and cleansers at low levels, it supports the skin's moisture retention without forming a heavy barrier. The compact dipeptide structure allows for efficient absorption, aiding in maintaining skin flexibility and comfort during daily use. Derived from fundamental building blocks of proteins, it mimics natural moisturizing factors found in skin.
