For years, the common wisdom around skincare has suggested that daily showers might not be ideal for maintaining healthy skin. But new research has challenged these long-held beliefs, especially when it comes to conditions like eczema.
Dr. Rosalind Simpson, a medical dermatologist at the University of Nottingham, recently shared some surprising insights based on her department’s latest study. “If you had asked me a few months ago, my answer might have been different,” she admits, referring to the historical view that daily showering could strip the skin of natural oils, disrupt its microbiome, and lead to dryness and irritation.
This concern about daily bathing causing skin damage has been common among dermatologists, with fears that frequent washing could lead to cracks in the skin, making it more vulnerable to allergens and bacteria. These cracks were believed to potentially trigger flare-ups of conditions like eczema and psoriasis.
However, a recent randomized controlled trial conducted by Dr. Simpson’s team on eczema patients has led to some unexpected conclusions. The trial involved 438 eczema sufferers, who were split into two groups. One group was instructed to bathe or shower six or more times a week, while the other group limited their bathing to once or twice weekly. Contrary to what might have been expected, the study revealed that frequent showering did not worsen eczema symptoms. In fact, there was no noticeable difference in the skin condition of those who showered daily versus those who showered less frequently.
Dr. Simpson’s key takeaway is that the frequency of washing does not seem to directly affect skin dryness or irritation, even for individuals with eczema. “The frequency of washing doesn’t correlate with increased skin dryness,” she explains, adding that this finding holds true regardless of whether someone has eczema or not.
However, Dr. Simpson cautions that the duration of showers can impact skin health. “The longer you’re in the water, the more it can dry out your skin, regardless of how often you shower,” she says. To minimize irritation, she recommends shorter, cooler showers.
Another factor that can exacerbate skin irritation is the type of products used during showers. Dr. Simpson points out that certain ingredients in soaps, gels, and shaving products—such as methylisothiazolinone, methylchloroisothiazolinone, parabens, and sulphates—can trigger allergic reactions or skin sensitivities in some individuals. She advises opting for products with minimal ingredients, avoiding those with strong fragrances or preservatives, to reduce the likelihood of irritation.
For those dealing with skin irritation, Dr. Simpson recommends switching to emollient creams instead of traditional soaps. These creams can provide a gentler, more soothing alternative for cleansing the skin.
Ultimately, Dr. Simpson emphasizes that the best shower routine is the one that feels right for your skin. “It’s important to listen to your body and adjust your routine according to what works best for you,” she says. “Everyone’s skin is different.”
In conclusion, the latest research suggests that daily showers might not be as harmful to your skin as once thought, especially when it comes to eczema. However, the temperature, duration of the shower, and choice of products can still make a significant difference in skin health.
