I'm having trouble getting a BBS around the lips without cutting myself. The worst areas are on the mustache area just above the corner of the lips. If I get cuts they end up there. Any strategies?
Or puffing up your lips by holding a little air in your mouth? Either technique may help to give you a less variable surface, so that you can more easily find the right angle.
