Eight hours a night on the wrong surface is undoing everything you're doing right. Here's what the science actually says.

Cotton is one of the most absorbent fabrics on earth — ideal for towels, catastrophic for pillowcases. Every night, it pulls your retinol, hyaluronic acid, and moisturiser directly off your face. Mulberry silk's natural protein structure (sericin) repels moisture instead of absorbing it. Your serums stay on your skin exactly where you applied them.

Cotton's rough fibres create friction as you move in your sleep — pulling on thousands of hair cuticles, causing them to lift, fray, and break. Silk's incredibly smooth surface has near-zero friction. Hair glides freely all night. Cuticles stay closed. You wake up with hair that looks like you didn't sleep at all — in the best possible way.

Silk's natural protein filaments thermoregulate — staying cool when you're warm and retaining warmth when you're cool. No more waking up hot. No more flipping to the cold side. Just consistent, undisturbed sleep. Better sleep is the most powerful beauty treatment there is — silk delivers both at once.
