How it works
The Hyaluronic Acid Mask is a 1ea sheet mask, used after toner, in place of your serum step, in the evening. The humectant it is built around is Sodium Hyaluronate, named nineteenth on its own ingredient list. The same list carries Allantoin, Dipotassium Glycyrrhizate and Ceramide NP, so the humectant is not the only thing on it worth naming. How much of the Sodium Hyaluronate stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. This is the Original Korean Formula, the sheet mask ETUDE sells in Korea, Sodium Hyaluronate and all.
Key benefits
- Sodium Hyaluronate, the humectant this sheet mask is built around
- Allantoin and Dipotassium Glycyrrhizate on the same list, actives
- Ceramide NP on the same list, a barrier lipid
- Biosaccharide Gum-1 on the same list, a polysaccharide
- Beta-Glucan and Glycyrrhiza Glabra (Licorice) Root Extract further down the same list
- Camellia Sinensis Leaf Extract and Zingiber Officinale (Ginger) Root Extract further down the same list
Key actives
Sodium Hyaluronatehumectant
Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it. It is the entry this sheet mask is named after, and the list carries it.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. It is named twelfth on this sheet mask's list, alongside Sodium Hyaluronate.
Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. The panel names it twenty-first on this sheet mask's list, beside Sodium Hyaluronate.
Ceramide NPbarrier lipid
Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy. It is named thirty-third on this sheet mask's list, alongside Sodium Hyaluronate.
Biosaccharide Gum-1polysaccharide
Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel. It is named seventh on this sheet mask's list, alongside Sodium Hyaluronate.
Where does this sheet mask go in my routine?
After toner, in place of your serum step, in the evening. Toner goes on before it, and the rest of the routine goes on after you take the sheet mask off. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Sodium Hyaluronate and not three changes at once.
Is this the Korean-market sheet mask or a US version?
The Korean-market one, Sodium Hyaluronate and all. We match this sheet mask to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
Does this sheet mask contain fragrance?
Yes. The ingredient list names Limonene. It sits on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this sheet mask is not the one.
What else is on the list besides Sodium Hyaluronate?
Allantoin, Dipotassium Glycyrrhizate and Ceramide NP. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Sodium Hyaluronate sits relative to them. Further down the same panel: Biosaccharide Gum-1, Beta-Glucan and Glycyrrhiza Glabra (Licorice) Root Extract.

How to use
- Use the Hyaluronic Acid Mask after toner, in place of your serum step, in the evening.
- Apply the mask sheet on your face evenly. Remove after 10 to 20 minutes and then gently massage for better absorption.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Patch test this sheet mask on a small area and wait a day before using it more widely, especially with Sodium Hyaluronate on the list.
- This list names Limonene, so skip it if fragrance components are something you avoid.

Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.
