I'm having much difficulty with shaving the bristly hairs at the corners of my mouth. Granted they are not that noticeable unless up close in the mirror, buy I know that they are there and can feel them. I am trying my best to remove them by shaving across the grain from my ear to the corner of my mouth and the from the corner back to my ear. Additionally, I try to make an "o" face and flatten my skin, but to little avail. I've also noticed that if I try to hard to shave down the hairs in this area, I receive small cuts around the corners. The hairs tend to be almost a quarter of an inch and right on the edge of my lips and the skin on my face. Thanks in advance.
