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. Not surprisingly, it is most often found in glycerin-based blends that contain peptides. The recommended range for these blends is typically 2–5%.

In its raw form, it is a white solid. N-hydroxysuccinimide has no known safety concerns.
