Should You Cleanse After a Face Mask?

Saturday Skin Quench Intense Hydration Masks ($30)

Unlike clay masks, the main purpose of sheet masks is to hydrate the skin. Sheet masks are soaked in a serum or essence that adds a big punch of moisture. You should apply to a clean, freshly-cleansed face, and once the mask has been left on for 15-20 minutes and removed, you simply rub the rest of the serum into the skin. There's no need to wash your face after using one, but for even more hydration you may want to finish with a night cream.
