I have had the same experience. The silicon skirt seems to work better when it "sticks" to your skin a little. Right after cleaning, which is a good thing, the silicon will lift and roll easier and leak.
As far as a solution, I've put a little water on the mask skirt and that helps, but really just getting some more oil from your skin seems to be the best thing. I've gotten in the habit of just filling the sink a little and "sloshing" the mask to clean it daily. It doesn't remove all the oil but keeps it from getting too dry.
By the way, make sure the soap you're using is mild, no antibacterial, scents, or oils.
Hope this helps!
Thanks for all the replies.
jdireton: I will try the water trick as you suggested tonight. Hopefully it will make it sticky enough to return to normal.
The leakage is not too serious as to cause major problems with the treatment, but I now find that I have leakage under the chin making a hissing noise which wakes me up and also getting some buzzing on my cheeks that was not there before. This buzzing has caused me to dream that this was part of my normal breathing and I could not figure out how to stop making that noise while I was trying to hide from someone (almost a nightmare :grin: ).
