Skin health experts have issued a strong advisory to Nigerians, cautioning against the frequent use of bath sponges, particularly loofahs and synthetic mesh varieties, warning that overuse could lead to serious skin damage, infections, and long-term dermatological issues.
Top dermatologists raised concerns that bathing with sponges more than two to three times a week could compromise the skin’s protective barrier, increasing vulnerability to conditions such as dryness, rashes, acne, irritation, and bacterial or fungal infections.
Dr. Edesiri Ighorodje, a consultant dermatologist and venereologist at the University of Uyo Teaching Hospital, stated that while sponges are widely used across Nigeria for maintaining hygiene in the tropical climate, many users are unaware of their exfoliating effect, which, when done excessively, could result in unintended harm.
“Bath sponges exfoliate the skin physically. Though exfoliation is beneficial, it should be limited to once or twice weekly. Over-exfoliating can lead to a broken skin barrier,” Ighorodje explained.
She warned that a compromised skin barrier not only causes irritation and flare-ups in people with conditions like eczema or urticaria but also increases skin permeability, making it easier for harmful substances in products like bleaching creams to penetrate and cause more severe reactions.
“Even people without sensitive skin can develop allergic reactions if the skin barrier is weakened,” she added.
The specialist noted that frequent scrubbing, especially among individuals who use harsh skin-lightening products, can intensify dryness, irritation, and acne outbreaks.

Despite Nigeria’s humid and hot climate that encourages sweating, Dr. Ighorodje emphasized that moderation is essential, especially for individuals prone to skin allergies. She recommended discontinuing sponge use altogether for those with sensitive skin conditions or signs of compromised skin, to reduce flare-ups and discomfort.
Dr. Ifeanyi Umeh, another practicing dermatologist, echoed these concerns, stressing that many Nigerians unknowingly misuse sponges, failing to wash or replace them regularly. According to him, sponges should be cleaned after each use and replaced every two to four weeks to avoid contamination.
“Dirty or damp sponges can serve as breeding grounds for harmful microbes like Staphylococcus aureus, Pseudomonas, and Candida, all of which can cause severe skin infections,” Umeh warned.
He noted that many people mistakenly believe scrubbing harder equates to better hygiene. However, excessive friction strips the skin of its natural oils, weakening its defenses and opening the door to eczema, bacterial infections, and contact dermatitis.
Dr. Umeh also advocated for alternative methods, including the use of soft washcloths, proper drying of sponges, regular replacement, and moisturising after bathing as a way to protect the skin.
Both dermatologists called for increased public awareness campaigns to educate the public on proper hygiene practices, especially in urban areas where skin-related complaints have risen in recent months.
“The issue goes beyond personal hygiene—it’s a growing public health concern,” Dr. Umeh concluded.
