Silk or cotton pillowcase? What really happens to your skin and hair overnight

Your skin and hair don't "sleep."
During sleep, they renew themselves and react to whatever comes into contact with them – including the pillow.

Cotton is a very absorbent material.
It absorbs moisture, sebum, and skincare products, while simultaneously creating microscopic friction.

Silk has a naturally smooth texture, which creates a gentler environment for skin and hair.
Mulberry silk is valued precisely for its delicate feel and its ability to maintain natural balance.

The difference is not a promise.
It's a feeling that accumulates over time.
