Loofing, often referred to as "loofah," involves the use of a loofah sponge, which is derived from the fibrous interior of the loofah plant (Luffa). It is commonly used in bathing and skincare routines for exfoliating the skin and enhancing circulation. Loofahs can be used wet or dry and are popular for their natural, biodegradable properties. In addition to personal care, loofahs can also serve as eco-friendly cleaning tools.
