There was a guy in our fraternity who had a facial beard like that. He had the most densely packed facial hair I’ve ever seen and there were no typical blank spots. I think it grew across his upper cheekbones toward his nose.
I get the wolf man beard up my cheeks.
I just go to a proper old fashioned barber with a straight razor in the regular. It’s really the only solution. You need a second person to look at you to get your face balanced.
