I have two indents in the middle of my forehead due to Fisher and Paykel HC244 which do not disappear even after 24 hours. I have tried loosening the straps but then I loose the seal. Any suggestions?
Try a different mask. I think the Quattro left permanent dents in my forehead. I even finally cut bangs to cover them. Pad-a-cheek didn't stop the indentation, but a Comfort Gel mask did. (Of course, now my nose is rubbed raw!)
