Description and Uses
                                            N-hydroxysuccinimide is a synthetic ingredient used in cosmetics as an ester to soften and condition skin. It's also a reagent, a substance used to trigger a reaction that leads to a new substance, such as peptides and polymers.
N-Hydroxysuccinimide is used in cosmetics and beauty products as an ester often seen in eye creams. N-hydroxysuccinimide activates the elimination of blood originated pigments responsible for dark color and inflammation that causes under eye circles. "Infra-orbital shadows are due to the accumulation of hemoglobin and its coloured degradation products - biliverdin, bilirubin and iron - in the dermis and epidermis ... N-hydroxysuccinimide renders the iron soluble for natural elimination" (source).
                                        
N-hydroxysuccinimide (NHS) is often used to assist carbodiimide-mediated peptide coupling by forming an active ester intermediate via condensation of the surface carboxyl group and NHS. The NHS-reactive ester intermediate is susceptible to nucleophilic attack by primary amines and results in the formation of stable amide bonds between the biomaterial surface and the N-terminus of the peptide.
