"Loofahs are good for removing dead skin cells leaving the skin smooth and conditioned. Scrubbing the skin two to three times a week will enhance circulation and promote the excretory function of the skin," explains cosmetic dermatologist Dr. Paul Jarrod Frank.
Due to their abrasiveness and the fact they can harbor bacteria, mold and germs, Dr. Elizabeth Tanzi, co-director of the Washington Institute of Dermatologic Laser Surgery, not only cautions against using a loofah too roughly and too frequently; she also warns that sharing them is a big no-no.
Dr. Stafford Broumand, plastic surgeon and associate clinical professor of plastic surgery at the Mount Sinai Medical Center, echoes this warning adding, "Bacterium is attracted to moisture and loves to grow in the nook and crannies of a loofah. Some of the bacteria might be something like P. aeruginosa (which has been linked to drug-resistant infections)."
"The most likely route of infection is through broken skin -- nicks and cuts from shaving are particulary susceptible," says Dr. Heidi Waldorf, the director of laser and cosmetic dermatology at The Mount Sinai Medical Center in New York. "Infections can show up as folliculltis (red bumps and pustules at hair follicles) or as impetigo (yellow-oozing or crusting on a red base)."
