[Marvel] How does Deadpool show expressions through his masks?

Sorry, I did a quick research and found nothing about it. Is the fabric special?

Most superhero (and some supervillain) masks are made of fabrics incorporating Unstable Molecules, a substance discovered by Dr. Reed Richards which is both resilient, and extremely flexible. It is incredibly common for masks using unstable molecules to react to the wearer's expressions in ways which might otherwise seem ridiculous and implausible. 

Unstable Molecule Fabric now available for cosplayers at Jo-Anns.
