Ingredient analysis and how the ad lines read
Read on 2026-09-27
What is this product?
Mediheal's vitamin C Essential Mask is a sheet mask sold in boxes of ten 24 ml sheets by the Korean brand, filed as a brightening functional cosmetic. Its 44 entry list puts niacinamide third, a vitamin C ether derivative (3-O-ethyl ascorbic acid) in the middle and plain ascorbic acid near the end, alongside a spread of B vitamins, glycerin, panthenol, hydroxyethyl urea, sodium hyaluronate and ceramide NP. There is no fragrance entry, but geranium flower oil and the allergens citronellol and geraniol are listed. The brand pitches pure vitamin C for dull, blemished skin; the list places plain ascorbic acid late.
What makes it different?
Within the brand's Essential Mask line it is the box that pairs niacinamide in third place with two vitamin C entries, an ether derivative mid-list and plain ascorbic acid near the end, under a brightening filing; the tea tree and madecassoside boxes in the same line list neither vitamin C entry.

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