Dermatologists are sounding the alarm over the widespread daily use of bath sponges, cautioning that frequent scrubbing with loofahs and synthetic mesh may harm the skin’s natural barrier and increase the risk of irritation and infections.
In Nigeria, it’s common practice to use sponges during every bath. But according to skin care experts, this habit could be doing more harm than good. “Bath sponges, especially abrasive ones, can strip away the skin’s natural oils and cause microtears,” said Dr. Amaka Okoye, a dermatologist at the University of Port Harcourt Teaching Hospital. “This weakens the skin barrier, making it easier for bacteria, fungi, and other pathogens to penetrate.”
Beyond physical damage, sponges themselves can become contaminated if not properly maintained. The warm, damp conditions in bathrooms create an ideal environment for microbial growth. “Many people don’t realize their bath sponge could be harboring harmful microbes,” Dr. Okoye explained. “Without regular cleaning and proper drying, these tools can spread bacteria and fungi directly onto the skin—especially dangerous for those with cuts or sensitive skin.”
To reduce the risk of skin damage, dermatologists recommend using sponges only 2–3 times a week and opting for gentler alternatives for daily cleansing. “Soft washcloths or even your bare hands with a mild cleanser can be just as effective,” said Dr. Chidi Ekwueme, a Lagos-based dermatologist. “Those with eczema or sensitive skin should avoid sponges altogether, as they are more prone to irritation.”
Proper sponge hygiene is also essential. Sponges should be rinsed thoroughly after use, stored in a dry, well-ventilated area, and replaced every 4 to 6 weeks. Synthetic mesh sponges, although popular, are harder to sanitize than natural loofahs and should be cleaned regularly with hot water or a disinfectant.
The warning has sparked mixed reactions among the public. “I had no idea a simple bath sponge could be risky,” said Temi Adebayo, a Port Harcourt resident. “I’m definitely switching to something softer now.”
Dermatologists are calling for greater awareness around bathing habits. “Cleansing should protect the skin, not damage it,” Dr. Ekwueme said. “A few small changes in your routine can make a big difference in maintaining healthy skin.”
Experts also encourage individuals to consult a dermatologist to determine the most suitable skin care routine. As public awareness grows, professionals hope Nigerians will embrace safer, more skin-friendly bathing practices.
