- how to use
Step 1

Smooth the mask onto clean, dry skin, gently pressing out any air bubbles.

Hydrogel Masks vs The Usual Options
Most sheet masks dry out before they finish working, and heavy night creams can feel greasy by morning. Serein's hydrogel mask stays active for hours, delivering collagen deep into skin without any greasy residue.
