Methoxy Cinnamido Propyl Hydroxysultaine is a cinnamic acid derivative incorporating a hydroxysultaine (zwitterionic) moiety, used in skincare for its antioxidant and skin-conditioning properties and potential to help mitigate environmental and UV-related oxidative stress. It is primarily found in serums and other leave-on cosmetic formulations.
