Wiping your face with the wireless earphones you hold to your face every day is good for preventing small bumps on your jawline.

For a while, I also had tiny bumps appearing only in that area and didn't know why. However, I realized that the long stems of my wireless earphones (like AirPods) that touch my face while I wear them for calls during my daily commute were covered in a massive amount of oil and dust. Since then, I've established a routine of thoroughly disinfecting the entire earphone with an ethanol swab as soon as I get home. After getting into this habit, the unexplained breakouts around my ears and jawline completely disappeared. Everyone, please check the hygiene of your earphones as well.
