Official ingredient list ↗03 / YOUR ROUTINE
Cleanse and apply toner. Unfold the mask, align and stretch it to fit the face, leave on 10–20 minutes, remove, and pat remaining essence.
Official directions checked 2026-10-24 ↗Check the exact product label, shade or variant where relevant, and the current seller terms before buying.
The US listing identifies a 10-sheet pack with 18 mL of essence per sheet. The flexible sheet is designed to stretch and cling to the face; after cleansing and toner, leave it on for 10–20 minutes and pat in the remaining essence.
The formula combines a Centella-derived complex with green tea water and eight hyaluronic-acid forms. The brand calls it pH-balanced but does not publish a pH value on this page. This is a short leave-on mask step, not a rinse-off treatment.
Official product reference ↗Beauty of Joseon tested temporary redness caused by heat, rather than persistent redness. It reports the following single-use results in 22 subjects. The separate acne-prone and sensitive-skin assessments used longer study periods.
The page does not publish the full protocols or comparators. These studies do not establish treatment of acne or persistent redness, or guarantee that a user will have no reaction.
| Measure | Reported result | Study |
|---|---|---|
| Temporary heat-related redness | 87.42% improvement in soothing measure | 22 subjects · single use |
| Skin moisture | 250.13% improvement | 22 subjects · single use |
| Transepidermal water loss | 23.69% reduction | 22 subjects · single use |
| Non-comedogenic assessment | Test completed | 22 subjects · 4 weeks |
| Hypoallergenic assessment | Test completed | 52 subjects · 5 weeks |
The US directions say 10–20 minutes, then remove the sheet and pat in the remaining essence.

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.
