COSRX sells snail mucin as a cleanser, essence, eye cream, face cream and masks, so the right directions depend on which product you own. Advanced Snail 96 Mucin Power Essence and Advanced Snail Radiance Dual Essence are separate products, despite names that sound like successive levels of the same video game.23

What order should you apply them in?

For the products already in your routine, COSRX places them in this order:

  1. 1Cleanse before applying the products you leave on.
  2. 2Apply toner, if you use one. COSRX places an exfoliator after toner in its routine.
  3. 3Apply the snail sheet mask, if you are using it. Spread the sheet evenly over your face, remove it after 10 to 20 minutes, and gently pat in the remaining essence.
  4. 4Apply your essence after the mask step.
  5. 5Apply eye cream after essence.
  6. 6Finish with face cream.

Which snail mask do you have?

The 10 to 20 minute directions above belong to the Advanced Snail Mucin Power Sheet Mask. COSRX also sells an Advanced Snail Mucin Glass Glow Hydrogel Mask; use that mask's own package directions rather than borrowing the sheet mask's timing. The shared snail branding is not a shared instruction manual.13

What should you expect?

The sheet mask is intended for hydration and contains snail secretion filtrate, glycerin, panthenol and sodium hyaluronate. Treat hydration as its purpose, rather than setting a deadline for changes to wrinkles or other skin concerns.1

Who should be careful?

Skincare ingredients can cause allergic contact dermatitis, an itchy skin reaction to something touching the skin. Stop using a product if it causes irritation. For children and teens, research on many cosmetic skincare ingredients is limited, and extra hyaluronic acid has uncertain benefits in young skin.4
