Cosmetic chemistry is the study of the formulation and development of products used for personal care and beauty. This field combines principles from chemistry, biology, and engineering to create items like skincare, makeup, and fragrances. Cosmetic chemists work to ensure these products are safe, effective, and stable over time. In addition to creating new products, cosmetic chemists also analyze existing formulations to improve their performance. They consider factors such as skin types, allergies, and environmental impact when developing cosmetics. This ensures that consumers have access to high-quality products that meet their needs and preferences.
