Mediheal Dermaplus Low Molecular Hyaluronic Acid Mask

Ingredient analysis and how the ad lines read

Read on 2026-09-12

What is this product?

Mediheal Dermaplus Low Molecular Hyaluronic Acid Mask is a ten-sheet box of 22 ml essence-soaked sheets built on a humectant stack running glycerin, butylene glycol and dipropylene glycol at positions two through four, with sodium hyaluronate declared at 202 ppm in position eighteen. The label is named for low molecular weight hyaluronic acid, and every hydrolysed hyaluronic entry on its panel is declared at 1 ppb, seven of them, while no molecular weight is published for the 202 ppm entry. There is no lipid phase, no declared fragrance and no exfoliating acid; 콘민트오일 sits at twenty-one and is the one entry that limits fit. The brand cites no test of any kind and the statutory block reads 심사필여부 해당없음, consistent with a panel carrying no notified functional active. Suited to dehydrated, tight or oily-dehydrated skin; cautioned for mint-reactive skin and for skin needing an occlusive.

What makes it different?

Two things distinguish it in its step. The brand prints concentrations for its hero family rather than leaving them undisclosed, and those printed numbers are what undercut the product name: 202 ppm for the plain form against 1 ppb each for the seven derivatives the name points at. And it is a hydrating sheet with no lipid phase whatsoever, which makes it a delivery step rather than a finishing one, and which is why what follows it in a routine matters more than usual.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

This brand publishes its ingredient list in Korean only. Names below are the matching INCI names from the Korean Cosmetic Association ingredient dictionary.

Key ingredient

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

We could not place these in the list above: 콘민트오일, 폴리글리세릴-10라우레이트, 폴리글리세릴-4라우레이트, 옥틸도데세스-16

Did the ad claims hold up?

backed by evidence1

  • 1. After cleansing, refine the skin with toner. Take out the mask sheet and apply it to fit the shape of your face. 2. After about 10~20 minutes, remove the sheet and gently pat the remaining essence into the skin to help it absorb.
