Angular Cheilitis: Why your cotton pillowcase deepens lip fissures

Angular cheilitis is a painful inflammatory condition that forms deep, bleeding cracks and sores at the corners of your mouth. It is caused by an overgrowth of Candida fungi or bacteria. While most treatments focus on topical antifungal ointments, the underlying mechanical cause is often ignored: the absorbent micro-climate created by your cotton pillowcase.

The Saliva Absorption and Maceration Trap

During the night, saliva naturally pools at the corners of your mouth, especially when sleeping on your side. Cotton is highly porous; it sucks up this moisture and holds it directly against your skin. This creates a wet, warm micro-environment that triggers a process called maceration. The skin breaks down completely, allowing fungi to proliferate and split the lip corners open into painful fissures.

Absolute Zero Friction

To heal angular cheilitis, you must eliminate all mechanical friction. When you turn your head, a rough cotton weave scrapes the open cuts, tearing the fragile healing tissue. This is why the Silkhouse pillowcase features a strict zero-embroidery mandate. We completely forbid raised logos or thick decorative borders. You sleep on 100% pure, uninterrupted clinical silk.
