K-beauty, read closely — ingredients, textures, and the choices between them.
COSRX
A hydrogel mask with a published removal cue of about 2–3 hours or transparency. COSRX highlights peptides, collagen and other ingredients; the product page does not establish an individual outcome.
| Format | Hydrogel mask · about 2–3 hours or until transparent |
|---|---|
| Pack | Amazon listing: 3 sheets; official U.S. page offers 1 and 3 sheets |
| Highlights | Six peptides · low-molecular-weight collagen · niacinamide · hyaluronic acids · ceramides |
| Use | After cleansing and toner or serum; massage in remaining essence |
Consider it for: You prefer a hydrogel mask with a longer wear time than a conventional short-session sheet mask and a clear removal cue.
Based on brand information and published sources, not a hands-on review.
01 / TEXTURE
COSRX describes a hydrogel sheet that becomes transparent during wear. The pink mask shown on the pouch is printed packaging artwork.
03 / YOUR ROUTINE
After cleansing, apply toner or serum, remove the protective films, and place the mask on your face. Remove after about 2–3 hours or when transparent, then massage in remaining essence. Overnight use is an optional brand tip.
For external use only. Keep it out of the eyes; rinse thoroughly if contact occurs. Use immediately after opening because it may dry out.
CHOOSING THIS FORMULA
COSRX says to remove it after about 2–3 hours or when it turns transparent, then massage in the remaining essence. The brand also offers overnight use as a tip. The main removal direction is 2–3 hours or transparency; not every use must last overnight.
COSRX calls out six peptides and 200 Da low-molecular-weight collagen, along with niacinamide and N-acetyl glucosamine. It also highlights five hyaluronic-acid types and five ceramides. These are brand ingredient descriptions; the product page does not show controlled results for this finished mask.
This hydrogel mask has a 2–3-hour or transparency removal cue. COSRX Advanced Snail Mucin Power Sheet Mask is directed for 10–20 minutes. Those are use-format differences, not evidence that one performs better.
Apply after cleansing and toner or serum, remove the protective films, then place the mask on your face. COSRX says to use it immediately after opening because it may dry out. Keep it out of the eyes and rinse thoroughly if contact occurs.
The U.S. product page does not provide a participant count, control group, measurement method or full product-test protocol. Treat benefits as brand claims, not guaranteed or independently verified outcomes.

Original ingredient list ↗COMMON QUESTIONS
COSRX suggests overnight use as a tip, but its main direction says to remove it after about 2–3 hours or when transparent. Follow package directions.
Official product reference ↗The Amazon U.S. listing is a 3-sheet pack. COSRX's official U.S. page offers 1-sheet and 3-sheet options.

Official product reference ↗COSRX says to avoid eye contact and rinse thoroughly with water if contact occurs.
Official product reference ↗CHOOSING BETWEEN PRODUCTS
Both are hydrogel masks with longer wear instructions than a conventional sheet mask. COSRX gives a 2–3-hour or transparency cue; medicube’s PDRN gel mask has separate overnight-use directions. Compare wear time and the complete formula; a transparent sheet is not a measurement of ingredient penetration.

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.
