The international cosmeceutical sector has experienced unprecedented expansion, compelling regulatory bodies to enhance and update systems to tackle consumer protection, product effectiveness, and ethical issues. This review critically evaluates and contrasts regulatory settings in key markets, such as the European Union, United States, Canada, Japan, China, India, and Brazil. The examination is concentrated on key features including product definitions, pre-market approval procedures, and ingredient regulation, labeling requirements, post-market surveillance, and integrating ethical and environmental considerations. The outcome shows significant advances in regulatory harmonization, especially in the area of ingredient safety and adverse event reporting; however, there are still considerable challenges. Pioneering among these are the lack of a standard definition for “cosmeceuticals,” highly variable ingredient limitations, and uneven application practice across jurisdictions. The speedy growth of e-commerce and cross-border sales additionally complicates regulatory control, adding to the possibility of non-compliant or counterfeited products reaching consumers. The review also identifies a shortage of empirical evidence to document the actual impact of recent regulatory reforms in the real world, as well as on innovation and market access. The present study recommends the promotion of international harmonization of standards, enhancement of post-market surveillance, convergence of ethical and sustainability dimensions, and targeted support for small- and medium-sized enterprises. Henceforth, while important progress has been achieved, the future of the industry rests on creating nimble, science-informed, and internationally harmonized regulatory systems that can keep pace with changing technologies and consumers’ and public health priorities, ensuring both consumer safety and industry innovation.
