Sheet Mask

Written by Reviewed by the SYNC editorial team Published Last reviewed Editorial standards

Sheet Mask — a single-use facial treatment made from a thin sheet of cotton, hydrogel, or bio-cellulose that is saturated with a serum-like essence and pressed onto the face for a set period. The occlusive sheet slows evaporation, helping water and active ingredients absorb into the skin's surface while it sits in place.

Key points

  • Sheet masks primarily deliver a short-term boost of hydration and a plumped, refreshed appearance rather than lasting structural change.
  • They are typically worn for 10 to 20 minutes, since leaving one on until it dries can draw moisture back out of the skin.
  • Common essence ingredients include humectants like hyaluronic acid and glycerin, along with soothing botanicals or niacinamide.
  • Any residual essence can usually be patted into the skin instead of rinsed off, and moisturizer afterward helps seal it in.

Frequently asked

How often can I use a sheet mask?

Most formulas are gentle enough for daily or several-times-weekly use, though frequency depends on the specific actives and your skin's tolerance. Hydrating masks are generally the most suitable for frequent use.

Should I moisturize after using a sheet mask?

Yes, applying moisturizer afterward helps lock in the hydration delivered by the essence. Without it, some of the added water can evaporate from the skin's surface.
