4. Touching Your Face Frequently

Constantly touching your face transfers bacteria, dirt, and oil from your hands onto your skin, increasing the risk of clogged pores and breakouts. Common habits include resting your chin on your hands, rubbing your forehead, or picking at blemishes—all of which can introduce unwanted microbes and worsen existing skin issues.
Health authorities like the Centers for Disease Control and Prevention (CDC) recommend keeping hands clean and avoiding unnecessary contact with your face to reduce irritation and prevent the spread of bacteria that can damage your skin.
