It could be bacteria-related that occurs from the rubbing of the mask to your skin. I have two suggestions. 1. Look for a product that contains 2% salicylic acid to apply to the area AM and PM as it will take care of bacteria on contact. Some companies make a gel type that is less drying than a liquid. 2. Go to www.ApneaPartners.Org and look under Product and Treatment Support/CPAP Comfort Support for Mask Liners that are disposable.

Any chance with the Covid issues that the FDA would allow Zoom fittings for the clinical trials? Telemedicine is a big thing! I am going to need a replacement soon and have a friend who would like one as well. This totally works for mouth breathers. Just a thought!
Try a TAP PAP Nasal Pillow CPAP Mask with Improved Stability Mouthpiece
I am a mouth breather and have the best success with the TAP PAP Nasal Pillow CPAP Mask with Improved Stability Mouthpiece. It is a combination dental and nasal pillow mask. Nothing touches my face except for the nasal pillows or my head. I have had the highest scores since switching to this mask.
You might try something called a Tap-Pap. It is a combination dental nasal device. I have got the best results and scores with it.

I like either MyPillow or a Microbead Pillow because they are not solid surface and they break up for better neck support.
