Scrub is a type of topical medication delivery system used for the treatment of various skin conditions. It is a preparation that contains active ingredients and exfoliating agents, such as salt or sugar crystals, that are used to remove dead skin cells and other impurities from the skin. The scrub is typically applied to wet skin, massaged into the skin in a circular motion, and then rinsed off. Scrub is commonly used to treat conditions such as acne, rough skin, and uneven skin tone, as well as to provide a general clean and revitalization to the skin. It is important to always follow the instructions of a healthcare professional when using medicated scrubs to ensure proper dosing and to avoid any adverse reactions. Additionally, it is important to use the scrub as directed, avoiding excessive use or use on sensitive areas of the skin.
