Silk vs Regular Sleep Mask — What's the Difference?.

Do you need an expensive silk eye mask? Or will a $5 one work?

Skin and hair

Silk reduces friction. If you wake up with sleep creases on your face, or tangled hair, silk helps. Regular cotton pulls on skin.

Breathability

Silk is more breathable. You don't feel sweaty under it. Cheaper masks can trap heat.

Light blocking

Both block light equally. The contoured design matters more than the material.

Price

Silk costs $15-25. Regular is $5. If you sleep hot or have sensitive skin, silk is worth it. If not, save the money.
