Frequent handwashing amidst the COVID-19 outbreak: prevention of hand irritant contact dermatitis and other considerations

Abstract

On the one hand, frequent handwashing is important for stopping the cycle of sustained transmission of COVID‐19; on the other, the frequent use of hygiene products, particularly harsh soaps and other potent detergents, can be associated with irritant contact dermatitis 3 and related complications including methicillin‐resistant Staphylococcus aureus colonization, particularly in critical workplaces such as intensive care units, emergency care, and isolation wards during an ongoing epidemic. 4 Here, I offer some tips to help prevent irritant contact dermatitis of the hands due to frequent handwashing during this COVID‐19 outbreak: Use soap‐free cleanser (synthetic detergent vs harsh soaps and potent detergents) with water if hands are visibly soiled or dirty. Since synthetic detergents have a neutral or slightly acidic pH and have relatively high free fatty acid content, these are less irritating for the skin and have a moisturizing effect, helping prevent dryness and hand irritation. 5,6 Use alcohol‐based cleansers or other antibacterial hand rub for cleaning and disinfecting hands when they are not visibly dirty. From a hygiene viewpoint, paper towels are superior to electric air dryers. 10 Apply an ointment‐based emollient during work time after hand washing and after work, at home, to support the regeneration of the skin barrier. 11 Avoid a water‐based moisturizer (humectant) alone (eg, glycerin, panthenol, urea, gelatin, hyaluronic acid, alpha hydroxy acids), as it can enhance trans‐epidermal water loss and can also cause potential dryness as the water contents evaporate. 12,13 Ensure proper and reasonable use of gloves, and change gloves frequently during prolonged work periods, especially healthcare workers.
