Eight hours a night, against your face. Cotton was designed to absorb — it's what makes towels work. It's also why a cotton pillowcase draws moisture and product off your skin overnight, and drags on your hair every time you move. Silk does neither. It's far less absorbent, and it has a much lower friction coefficient against hair, so there's less mechanical stress across a night's sleep. Less drag means fewer tangles and less breakage. Less absorbency means your moisturiser is still doing its job at 3am. That's the whole mechanism. It isn't complicated, and it doesn't need to be. Why 22-momme Momme measures how much silk you're actually getting — the weight of the fabric per unit area. Most silk pillowcases are 16 or 19-momme, and a good number are polyester satin sold as silk. Ours is 22-momme, roughly a third heavier than the standard: denser in the hand, heavier in the drape, and it holds up through washing rather than thinning out over a year. Why two is better than one Silk wants washing every week or two. While one's in the wash you're back on cotton — so a second means the bed is always covered.

What silk doesn't do It doesn't prevent wrinkles, treat acne or replace skincare routines. It does however change what skin and hair spend 8 hours against.
