Acne often shows up in spots where skin rubs against clothing, gear, or your hands because of something called acne mechanica. This type of acne happens when constant friction, pressure, or heat irritates the skin and clogs hair follicles with oil, sweat, dead skin cells, and bacteria.
Think about your cheeks. If you rest your chin on your hand a lot or press your phone against your face, that rubbing traps oil and bacteria right there. The skin gets red, inflamed, and pimples form before it can heal. The same goes for your scalp under tight hats, helmets, or headbands. The friction irritates follicles, mixes with sweat and hair products, and blocks them up.
During workouts, tight sports bras, straps, or helmets create even more trouble. Sweat builds up under the rubbing fabric, turning into a perfect spot for breakouts on your chest, back, or shoulders. Dirty gym equipment or shared towels add bacteria, making it worse.
Even everyday items play a role. Pillowcases that you do not change often rub your face at night, carrying old oils and germs back to your skin. Face towels with rough textures can scrape and inflame the area, sparking pimples.
Hormones can make it worse in rubby spots. Stress or monthly cycles boost oil production, and when that hits a friction zone like your jawline, acne flares up.
To cut down on this, switch to loose, breathable clothes that wick away moisture. Clean your phone and pillowcases regularly. Shower right after sweating with a gentle cleanser. Pick hair products and fabrics that do not clog pores.
