Try to go slow, no pressure, pay attention to the blade angle.
Did you face map the growth of your beard? You could also pull the skin a little to make it go around the angle of the chin.
That's a tough area for everyone. You just gotta work it out for yourself. Be conscious of what works and what doesn't.I am getting nicked under my chin. I'm not able to get as close a shaving in the area under my chin down to my adams apple and between those areas especially. I have a sharp chin and a kind of pronounced jawline, which makes it difficult. How should I go about shaving those areas?
