Pristine Luxury Dust Mite Pillow Cover - Queen 21x30

This worked to stop my allergies, but it caused acne! I think it breathes less than other, cheaper pillow covers, which probably makes it more effective at stopping dust mite allergies but it traps bacteria between my face and the pillow. After a couple weeks I switched back to my other cover, and the acne on my jawbone and cheeks cleared up.
