Cosmetic science is the study and development of products designed to enhance or alter the appearance of the human body. This field combines chemistry, biology, and dermatology to create safe and effective formulations for skincare, haircare, and makeup. Cosmetic scientists work to understand how different ingredients interact with the skin and hair, ensuring that products meet regulatory standards. In addition to product formulation, cosmetic science also involves testing for efficacy and safety. This includes conducting clinical trials and stability tests to ensure that products remain effective over time. Professionals in this field often collaborate with cosmetic companies and regulatory agencies to bring innovative products to market.
