My skin seems to be irritated, even bruised, or I have marks on my face. What should I do?
Your mask may be too tight. If your mask has a forehead arm or adjustment feature, try readjusting that first. Then, if necessary, readjust the headgear straps. You may have the wrong mask size. Consult your homecare provider for a mask fitting. Nasal pillows or a full-face mask may provide a better fit.
