Men may blame acne on sweat, shaving or the occasional missed shower. But one overlooked culprit could be the pillowcase. How often do you change your pillowcase?
Pillowcases collect sweat, skin oils, dead skin cells, saliva, and residue from hair and facial products. While this buildup does not automatically cause acne, it can aggravate existing skin conditions and irritate sensitive skin.
Dr Roop Saini, a consultant dermatologist at Doctors' Park in Parklands, Nairobi, recommends washing bed linen at least once a week, with more frequent changes for men who sweat heavily at night, have oily or acne-prone skin, or regularly use hair and beard products.
“If you sweat a lot at night, you have oily skin, or you use hair and beard products like oils, you may need to change your pillowcases a little bit more often,” she says, recommending twice-weekly changes in such circumstances.
Hot and humid weather can also cause beddings to become damp and greasy more quickly, making more frequent washing necessary.
Dr Saini says the concern is not simply the presence of sweat or oil, which are normal, but the accumulation of residue and repeated contact with the skin.
“For someone with sensitive or inflamed skin, the moisture from the bedding and the constant rubbing of your face on the bedding when you're asleep at night can make the irritation worse,” she says.
However, men should not assume that an unwashed pillowcase is the sole cause of persistent pimples.
Dr Saini also cautions against directly linking dirty bedding to acne, noting that evidence that pillowcases cause the condition is limited. Acne is influenced by several factors, including hormonal changes, excess oil production, blocked pores, inflammation and genetics.
“Someone can be very particular about cleanliness and still have acne because it's not the cleanliness or the lack of that causes the acne,” she says.
Nevertheless, bedding and grooming products may aggravate existing problems. Heavy hair oils and pomades can block pores when they transfer from the hair to the pillowcase and then to the face. Fragranced products can also irritate sensitive skin.
Men who notice spots around their hairline or cheeks should therefore review the products they use alongside their bedding changing habits.
For men with oily or acne-prone skin, Dr Saini recommends changing pillowcases every two to three days to see whether the adjustment helps.
She clarifies that this is a practical suggestion rather than a scientifically established rule for preventing breakouts.
Having a beard alone does not mean a man needs to change his bedding more frequently. Instead, he should keep his beard clean, use products his skin tolerates and avoid applying excessive oil.
Washing practices also matter. Dr Saini advises following the care instructions on bed linen, using the appropriate amount of detergent and rinsing thoroughly to remove residue.
Men with sensitive skin or eczema-prone skin should consider fragrance-free and dye-free detergents, while strongly scented fabric softeners may irritate some people.
Keeping spare pillowcases makes it easier to change them regularly without waiting for a full laundry load. Washing the face gently before bed and showering after exercise can also help remove sweat, dirt and excess oil before getting into bed.
For men whose breakouts persist despite these changes, the solution may require more than improved bedding hygiene.
“If the breakouts keep coming back or are painful, or you're healing with scarring, I would recommend that you see a dermatologist,” Dr Saini says.
Men experiencing bumps around the beard should also seek an assessment, as these may be ingrown hairs or inflamed hair follicles rather than acne.
