For many, the pursuit of healthy skin begins and ends with a meticulous routine of cleansers, serums, and moisturisers. Yet, a ubiquitous item in our daily lives, handled constantly and rarely cleaned, is quietly undermining our efforts: the mobile phone. Pressed directly against the skin, this device has emerged as a significant, yet often underestimated, contributor to irritation and even infection.
Dermatologists are increasingly observing a distinct pattern among patients, colloquially termed “phone acne,” even if it lacks a formal medical diagnosis.
Dr Munir Somji, chief medical officer and founder of DrMediSpa, explains that phones “come into contact with our hands, bags, make-up and countless surfaces throughout the day,” leading to a rapid accumulation of oil, bacteria, and debris.
He notes, “When the screen is then pressed against the skin, particularly along the cheek and jawline, that build-up can transfer onto the skin.” This, combined with the heat and friction generated by the device, can irritate the skin barrier and contribute to breakouts.
Consultant dermatologist Dr Derrick Phillips has witnessed similar cases in clinics, particularly during the pandemic when phone usage surged. He observed, “Some patients developed asymmetrical flare-ups of acne on one side of the face,” typically correlating with the side where they held their phone.
While experts agree phones are unlikely to be the sole cause of acne, they can certainly act as an aggravating factor, especially for those already prone to breakouts.
The contaminants lurking on our screens extend far beyond a vague notion of “dirt.” Dr Somji details that “phone screens tend to collect skin oils, sweat, make-up residue, dust and everyday bacteria from hands and surfaces.”
Dr Phillips adds that studies have identified common skin bacteria such as Staphylococcus aureus and Staphylococcus epidermidis on mobile devices, alongside dead skin cells and environmental debris. Given the frequency with which we check our phones and the infrequency of cleaning, this build-up is inevitable. Crucially, unlike many other everyday items, phones are often pressed directly against the face or handled by hands that then touch the face, creating a direct pathway for bacterial transfer to the skin.
The impact of a dirty phone goes beyond the occasional blemish. Dr Somji highlights that “the most common concerns tend to be breakouts and clogged pores, particularly along the cheeks, jawline and chin,” adding that “some people may also experience irritation or redness, especially if they already have sensitive or reactive skin.” Dr Phillips explains that it is a confluence of factors, not just bacteria. “The heat from the device, friction against the skin and the occlusion created when the phone is held tightly to the cheek can trap sebum, sweat and dirt in the pores,” he says, fostering an environment ripe for breakouts. Emerging research also suggests that short-wavelength visible light emitted from screens “may influence certain skin bacteria,” though its clinical relevance is still under exploration.
For those committed to their skincare, the solution to phone hygiene is straightforward: daily cleaning. Dr Somji advises, “Ideally, phones should be cleaned every day, particularly if you regularly hold them against your face,” or if you touch your face while using your phone.
He stresses that “even a quick wipe once a day can help reduce the build-up of oil and bacteria.” He also recommends increased vigilance after activities like workouts or when using your phone with make-up, both of which can increase screen residue. Dr Phillips concurs, stating that daily cleaning is the most effective preventative measure against bacterial transfer. This doesn’t need to be time-consuming; a quick wipe with an antibacterial product at the end of the day can yield significant long-term benefits.
However, the method of cleaning is as crucial as its frequency. Dr Somji recommends that “the safest approach is usually a soft microfibre cloth with a small amount of alcohol-based screen cleaner or disinfectant wipes designed for electronics.”
These products are formulated to eliminate bacteria without leaving irritating residues. Dr Phillips cautions against harsh household cleaning products, explaining, “Bleach or strong detergents can damage the screen and may leave residues that could irritate the skin.” Instead, opt for electronic-specific cleaners, avoid spraying liquid directly onto the device, and ensure the screen is fully dry before use.
Phones are not the only overlooked culprits in our daily lives. Dr Somji points out that “pillowcases, make-up brushes, reusable face cloths, headphones, hats and even glasses can all collect oil, bacteria and product build-up.” Dr Phillips further adds keyboards, laptops, and even car steering wheels to the list of items that can contribute to bacterial transfer. Simple adjustments, such as washing pillowcases weekly, regularly cleaning make-up brushes, and being mindful of anything that repeatedly touches your face, can significantly reduce irritation and breakouts.
Ultimately, effective skincare extends beyond the products we apply; it encompasses everything our skin comes into contact with.
