N-Hydroxysuccinimide
What is N-Hydroxysuccinimide?
N-Hydroxysuccinimide is a synthetic heterocyclic compound, chemically 1-hydroxy-2,5-pyrrolidinedione, with a five-membered ring structure containing nitrogen and oxygen. Produced through chemical synthesis, it belongs to the class of succinimide derivatives commonly used in cosmetics. As a skin conditioning agent, it appears in serums, creams, and eye-area products. In formulations, it interacts with the skin's surface layers, aiding in moisture retention and enhancing tactile qualities by supporting protein and lipid organization. This contributes to improved skin feel and resilience without contributing to pore blockage. Valued for its mild profile, it integrates well into multi-ingredient blends targeting texture refinement in daily skincare routines.
