A face mask, or facial mask, consists of clay, gel, enzymes, charcoal, or a mix of other ingredients. You apply the mask to your face using your fingertips or a brush.
Some masks are specifically designed as overnight masks (also called sleeping packs), and they’re generally safe to wear while sleeping.
Other masks may be too drying to leave on all night, but they could help as a spot treatment if you have a pimple.
Some gentle masks, either homemade or store-bought, can be safe to use overnight, though they may get your pillowcase dirty or cause dryness.
Sleeping with a face mask applied, especially one intended to be used overnight, has benefits for your skin.
Overnight face masks are essentially the same as thick nighttime moisturizers, but they have many active ingredients all working together at once.

- Certain ingredients like clay or activated charcoal may be too drying to use overnight. Avoid sleeping in masks containing such ingredients unless you have very oily skin.
- DIY masks or masks that don’t harden may be too runny to sleep in, possibly ruining your pillowcase and sheets.
- Avoid products with alcohol, which can be drying and damaging to your skin.
Most store-bought masks will have directions for use. Before you use one, test a little on your skin first to make sure it doesn’t cause an allergic reaction.
Generally, you apply a mask to clean, dry skin. Wait for it to harden or set before going to sleep to avoid ruining your bed linens.
If the mask is runny and won’t harden, consider putting a towel over your pillow.
Wash off the mask thoroughly in the morning, unless it has fully absorbed into your skin (as some hydrating masks do).
