Your face rests on your pillow for hours every night. Over time, pillowcases collect oil, sweat, dead skin, hair products and dust. All of that can transfer back to your skin, especially if you sleep on your side or stomach.

Dirty or rarely changed pillowcases may contribute to clogged pores and irritation, particularly if you already have acne-prone skin. Rough fabrics can also create friction, which may worsen sensitivity or breakouts along the cheeks and jaw.

A simple habit is to change pillowcases regularly – at least once or twice a week, and more often if your skin is very reactive or you use heavy hair products. Soft, breathable fabrics like cotton or certain blends are often better than rough, synthetic materials.

Bedsheets matter too, especially if you sleep without full nightwear or if body acne is an issue. Fresh, clean sheets reduce the mix of sweat and bacteria against your skin.

It’s not the only factor in acne, but it’s an easy environmental change that supports whatever skincare routine you’re already following.
