Think of an oval face not as a particular shape, but rather as a set of proportions: cheekbones just slightly wider than jawbones, and a balanced chin that’s vertically symmetrical with your forehead.
“Whenever a guy comes to me and asks for advice on his facial hair, I always try to find something that will help him approximate an oval face shape,” Guastella says. “That’s my rule.”
So if you’re an oval-faced guy, congrats: You don’t really need to balance anything out. In fact, if you go overboard on a beard or mustache, you can even end up throwing off your facial symmetry. Going clean-shaven is always a good option, as is a beard that hews fairly closely to your existing facial features.
