if your mask wont seal...talk to your doctor about getting it replaced or the manufacturer
i am tired of shaving daily, I have to wear a mask and it won't seal well if I don't shave and i like my shaving ritual, but not twice a day.
Seconding this. I've used mine with a full beard, with a goatee and clean shaven. If the silicone is good, your straps aren't worn out, AND the mask is properly fitted, it'll still work just fine. No farty noises blowing on your cheek giving you a near heart attack just as you start to doze off... Not that that's ever happened to ME......
