@morironman I totally understand and know that aging brings on wrinkles, but these don't really looks like aging wrinkles. What I'm puzzled about is that it started happening a few months after I started using the cpap mask. And it's in the cheek area where the mask sits nightly only. Nowhere else but there. I wash my face every night. I use olay night cream along with nacinamide cream both day and night. I have been so curious about is if it's a normal thing that happens while using the cpap mask. I have researched it, seen a dermatologist that couldn't tell me but only wanted to sell me her very expensive creams or go under the needles that insurance doesn't pay for and I've spoken to my sleep doctor to no avail as she doesn't know if and why it causes your face to wrinkle. It's all so frustrating because after a 1.5 year later I don't see results with my sleep, just seeing what it's doing to my face. Thank you very much for sharing your experience. Oh, I too end up taking the mask off during the night as I can't handle using it.
