A loofah sponge is a natural exfoliating tool made from the dried fibrous skeleton of the loofah gourd, a plant belonging to the cucumber family. When harvested and processed, the gourd's interior becomes a sponge-like material that is often used in baths and showers to help remove dead skin cells and improve circulation. Loofah sponges are popular for their eco-friendly properties, as they are biodegradable and can be composted after use. They are available in various shapes and sizes, making them suitable for different body parts. Regular use of a loofah can contribute to smoother skin and a refreshing bathing experience.
