I'm with Lodesman. I've discovered that there are good days and bad days regarding my mask leaking over many, many dives and having used many different masks. A good fit is the main thing regardless of beard. After shaving I had the same experience. Slathering various goops did not solve the problem. Only a good fit did.
I might have a great dive, over an hour on a tank, with no
leaks and the very next dive have trouble....don't know why. Beard or no beard.
