As a dive guide, I found that shaving is a must not only for appearance but your stubble can actually wear out the edges of the mask skirt causing minor leakage. For those divers with a stash,I find pulling the mask down on your lip and positioning the strap higher on your head helps. Unfortunately(?) smiling & laughing seems to break the watertight seal no matter what mask tricks you may use.
