Cosmetics are products used for enhancing or maintaining the appearance of the human body. They include skincare, haircare, fragrances, and personal hygiene products. While cosmetics can provide various benefits, they may also pose risks to consumers’ health and safety. As a result, many countries have established regulatory bodies to ensure the safety and efficacy of cosmetic products. Regulatory bodies are responsible for setting and enforcing standards for cosmetic products to protect consumers from potential harm. They evaluate the safety and effectiveness of ingredients used in cosmetics and establish guidelines for labeling, advertising, and packaging. Some of the major regulatory bodies that oversee cosmetics include the US Food and Drug Administration, the European Commission, and Health Canada. Regulatory bodies typically require cosmetic manufacturers to conduct safety assessments on their products and ingredients before they can be marketed to consumers. These assessments involve evaluating the potential toxicity, skin irritation, and other potential risks associated with the product or ingredient. Regulatory bodies also conduct postmarket surveillance to monitor adverse reactions and to ensure that products continue to meet safety and quality standards. Furthermore, regulatory bodies play a crucial role in ensuring that cosmetics are safe and effective for consumers. The regulations and guidelines they establish help to protect consumers from potential health risks associated with cosmetic products. The important regulatory frameworks governing cosmetic and herbal cosmetic products in various areas and nations have been briefly summarized in this chapter. It is crucial to follow these rules to guarantee product safety and safeguard customer interests. Companies need to keep aware as the cosmetics industry develops and reacts to the shifting regulatory environment.
