Based on brand information and published sources, not a hands-on review.
01 / TEXTURE
COSRX describes a natural-derived cellulose sheet designed to fit closely to the face. The official package photo shows the 10-sheet box; it does not demonstrate fit or skin feel.
03 / YOUR ROUTINE
After cleansing and toner, apply one sheet evenly to the face. Leave it on for 10–20 minutes, remove it, and gently pat in the remaining essence. Do not extend wear time based on user reviews; follow the brand direction and the pack you receive.
Tea tree leaf oil is listed. Check the full ingredient panel if you avoid that ingredient, and use the mask for the package’s stated time.
CHOOSING THIS FORMULA
The official listing identifies 10 sheets and 25 mL (0.84 fl oz) per sheet. COSRX says the cellulose sheet is designed to fit closely to the face. The package image helps confirm the product and count; it cannot show how a sheet will fit your face.
After cleansing and toner, apply one sheet evenly. Leave it on for 10–20 minutes, remove it, and gently pat in the essence left on your skin. No weekly frequency is given on the product page; follow the package directions.
COSRX lists snail secretion filtrate at 35,000 ppm. That is the brand’s stated concentration for this ingredient; it is not a published independent measure of hydration or an individual result. The full INCI below provides the rest of the formula for comparison.
Compared with MEDIHEAL Madecassoside Essential Mask, this COSRX mask highlights snail secretion filtrate and comes in a 10-sheet pack with 25 mL per sheet. The MEDIHEAL product is another 10-sheet mask, but its official product identity centers on madecassoside. Compare the complete labels and instructions rather than assuming one will suit every skin type better.
Tea tree leaf oil appears in the ingredient list. COSRX gives application steps but does not publish detailed product-test conditions on its U.S. page. If a listed ingredient is a concern for you, check the package you receive and patch test according to your usual care approach.

Calculations use complete ingredient lists for the stated market and product version. Listed names do not establish concentrations, equivalent effects or allergy suitability.
Explore products in the same use group with overlapping ingredient lists, then compare their texture, directions and ingredient differences.
Candidates share the page’s language, market context and use group and have a complete ingredient list available. Names are normalized for spacing and reviewed synonyms; duplicate names count once.
The default order divides shared names by all distinct names across both lists: 10 shared names out of 20 distinct names gives 10 ÷ 20. You can instead order by the number of shared names. Up to five candidates are shown.
Ingredient overlap does not establish equivalent effects or a cheaper substitute. Concentrations, ingredient order, finished-product tests and feel are not part of this calculation. Missing lists are not treated as missing ingredients.
