Dr Rosalind Simpson, a dermatologist at the University of Nottingham, has challenged the long-held belief that showering every day is harmful to the skin. Speaking about recent research, she revealed that daily washing does not necessarily lead to increased dryness or irritation.
Historically, experts warned that frequent showers could strip the skin of natural oils and beneficial bacteria, potentially causing cracks that allow bacteria and allergens to enter. This was thought to exacerbate conditions like eczema and psoriasis. However, a new randomised controlled trial on bathing in eczema patients has produced surprising results.
The study, involving 438 eczema patients, compared those who bathed six or more times a week with those who bathed only once or twice weekly. Contrary to expectations, the trial found no difference in symptoms between the two groups. “You’d expect daily bathing to dry out the skin more and worsen eczema symptoms, but it didn’t,” said Simpson. She believes this finding applies to people without eczema as well.
While frequency may not matter, shower duration and temperature do. Simpson advises shorter, cooler showers to avoid drying out the skin. She also warns that certain ingredients in shower gels, soaps, and shaving products—such as methylisothiazolinone, methylchloroisothiazolinone, sulphates, and parabens—can cause reactions. Opting for products with fewer ingredients and avoiding excessive fragrances and preservatives is recommended. For those experiencing irritation, using an emollient cream instead of standard soap may help.
Ultimately, Simpson emphasises that the best shower routine is one that suits your skin. “Do what makes you feel good—everyone’s going to be different,” she said.
