Ingredient analysis and how the ad lines read

Read on 2026-09-29

What is this product?

Mediheal's ceramide Essential Mask is a sheet mask sold in boxes of ten 24 ml sheets by the Korean brand, filed as a wrinkle-improvement functional cosmetic. Its 48 entry list is richer than a watery essence: glycerin, an emollient ester and shea butter sit in the top six, followed by fatty acid emulsifiers, ceramide NP at a printed 400 ppm, adenosine, a fragrance entry, amino acids and ectoin, with ceramides AP, EOP and NS at a printed 1 ppb each at the end. The brand pitches four ceramides at 90% purity and 24 hour moisture; no duration test is printed.

What makes it different?

Within the brand's Essential Mask line it is the box that lists four ceramides with printed levels (400 ppm for ceramide NP, 1 ppb for AP, EOP and NS) over an emollient base of shea butter and triethylhexanoin, under a wrinkle filing, and it carries a fragrance entry; the hyaluronate and madecassoside boxes list ceramide NP alone, last, with no fragrance entry.

What is in it?

Worth a closer look

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.
