How it works

A hydrogel mask holds its essence inside a gel sheet, which is why it stays put instead of drying out halfway through the way a paper sheet can. This one carries snail secretion filtrate near the front of its list, with niacinamide, panthenol and allantoin behind it. It goes on after toner, in place of the serum step, and what the sheet leaves behind is pressed in rather than rinsed off. Skin that looks dull and flat rather than congested is the case it fits. Two or three evenings a week, as an addition to the routine rather than a replacement for it.

Key benefits

  • Snail secretion filtrate is the second ingredient on the list
  • Five ceramide entries support a supple, cared-for barrier feel
  • Hydrolyzed collagen and five hyaluronate entries layer the hydration
  • The hydrogel turns transparent as it warms, a cue it has settled in

How to use

  1. Use the Advanced Snail Mucin Glass Glow Hydrogel Mask after toner, in place of your serum step, in the evening.
  2. Line the sheet up at the eyes first, then smooth it outward across the face so no air sits underneath.
  3. Take it off at the time the pack gives, press in the essence left on the skin, then follow with moisturizer.
  4. Two or three evenings a week. Do not wear it longer than the pack says; a hydrogel that has dried out pulls moisture back off the face.

Worth knowing

  • Snail secretion filtrate is animal-derived, so this is not a vegan formula.
  • Collagen here is not plant-derived, so this is not a vegan formula.
