Rosemary: The Formulators Secret Cosmetic Component With Panoramic Nature

This bibliographic review discusses rosemary (Rosmarinus officinalis) and the use of plant derivatives in cosmetic applications, a practice rooted in Egyptian civilization. Native to the Mediterranean, Rosemary has become naturalized in several parts of the world. It possesses many medicinal properties, and its extracts have been used in folk medicine, primarily for oral consumption. In cosmetics, the Labiatae family, which includes genera such as Salvia, Lavandula, and Thymus, is known for its high concentration of antioxidant molecules like polyphenolic compounds. Rosemary, an evergreen shrub that grows wild or is cultivated, produces fragrant volatile essential oils through glands on its leaves, with monoterpenes as the main components. Additionally, diterpenes, including carnosic acid, and other phenolic compounds are found in rosemary. This review includes a description of the plant's botanical and ecological characteristics, as well as the major bioactive constituents in its leaf extracts and volatile oils. After that, we investigate the applications of rosemary in cosmetics, including its protective effects, the products it is used in, and its safety in terms of toxicology. Another consideration is how the use of rosemary extracts could lead to the development of new medicated topical preparations, based on results from recent and ongoing studies.
