Beard trimming. The odd thing about a beard is you can change the general shape of your face by elongating it (growing a longer front), by making your face look wider, (fuller on the sides), etc..
For the last 34 years, I’ve trimmed mine just below the jawline. Now I match the bottom length to the angle of the top. It’s turned out to be my widest beard. I’m not a fan of really narrow ones.
