I use a full face mask (forma) and I can get it adjusted leak free . Then after about 5 hrs the leaks start . Around my nose blowing into my eye .
So what is happening , is the seal compressing or my face forming to the mask ? I can see the imprints when ever I see my mug in the mirror .
Its almost like an automatic alarm system .
A few different things could be causing that problem.
One thing to try that might help is to use a mask liner. There are several different brands. Just google CPAP MASK LINERS and you'll see what they are and get an idea of shape etc. - then, instead of ordering them, take an old clean t-shirt that you don't mind sacrificing and cut one out of that. The idea is to cut the shape of the mask surface that touches your face out of the t-shirt (only a little larger) and then cut out a hole in the middle of that piece that is almost large enough to expose your mouth and nose (the fabric will stretch some). Cut the whole piece out larger than what you think you'll need and cut the middle hole out smaller than what you think you'll need - extra fabric will give it room to move around a little. Put this on the mask then lean forward to place the mask on your face and then pull the sides of the cloth a little to stretch it enough so the cloth isn't covering your mouth and nose - see if it helps.
Some people like liners, some don't. This is a cheaper way to find out if you like them and if they help. Liners can be expensive because it's recommended to use a new one every night. They absorb the facial oils that could be contributing to the problem you are having. If you like them, then you can cut quite a few out of one old t-shirt. They also help get rid of those marks you say you are getting on your face.
If it works good for you and you decide to start using them every night and don't want to keep cutting up old t-shirts, you can buy a square yard of white 100% cotton knit jersey fabric and cut them from that. I found Amazon to be a good place to look.
If it doesn't work, you're just out an old t-shirt.
Of course; if you want to try liners, you could just order them and fork over the cash (upwards of a buck a piece), but where's the fun in that? If I ever willingly paid a dollar a piece for little pieces of cotton cloth, I would die a little inside.
