Loofahs — sometimes spelled luffas — are popular shower accessories used for cleaning and exfoliating your skin.

Some people think that “all-natural” loofahs are made of sea sponge or dried coral because of their coarse, spongy consistency. But natural loofahs are actually made from a gourd in the cucumber family.

Loofahs exfoliate and cleanse skin, but they aren’t the best shower choice for everyone.

Loofahs need to be taken care of properly so they don’t become carriers of bacteria that could make you sick. They can also damage sensitive skin.
