Shamban says there is — get this — pressure-induced acne. So if you’re constantly talking on your cell phone, playing violin, resting your hand on your chin, you’re giving your skin a double whammy. One, most of those surfaces are covered in bacteria and two, the actual pressure of those things on your face can cause acne.

The solution: Well the obvious one would be to stop pressing stuff against your face (so use your blue tooth headset and keep your hands off), but if you really can’t avoid it then at least clean any surfaces often to minimize bacteria.
