I also have a full beard and mustache and always have. I use a product called”Unpetroleum” that I pirchase at Whole Foods. It is similar to Vaseline , but as the name implies it is not petroleum based. It does not affect the silicone mask skirt. It comes in an orange and white toothpaste type tube and costs about $7. I put a glob on my mustache and spread it around before every dive and I don’t have leakage problems. I have recommended it for a long time to lots of other furry faced divers.
