Can cotton pillowcases irritate the skin around clear aligners?

Yes. The aligner's hard edge already presses against your cheek for eight hours, and cotton's rough texture adds extra friction right at that pressure point, while also drying out the skin. A perfectly smooth 100% mulberry silk pillowcase (no embroidery), like Silkhouse's, lets your cheek glide instead of catching, and preserves your skin's natural moisture throughout your treatment.

The Cotton Trap With Nighttime Aligners

Wearing clear aligners overnight means their hard edges rest directly against your cheeks and lips for eight straight hours. Mouth-breathing that often comes with them also dries out the surrounding skin. Cotton, a rough and absorbent fiber, adds friction exactly where the aligner's edge already presses, and pulls away what little moisture remains on your skin.

The Anti-Friction Solution: 22 Momme Silk

Mulberry silk has an exceptionally smooth surface that lets your cheek glide instead of catching on the aligner's edge with every movement. Its non-absorbent structure also leaves your skin's natural moisture in place. The result: less morning irritation around the mouth, night after night.

        "Beware of false good ideas: a pillowcase for nights spent wearing aligners must be perfectly smooth. Avoid embroidery and sewn-on logos — those synthetic threads add extra friction exactly where your skin is already under pressure. The minimalist design of Silkhouse silk isn't an aesthetic choice, it's a comfort requirement."
