How it works
The Hyaluronic Acid Water Essence is a 50ml essence, used after toner and before serum, morning and evening, on damp skin. The humectant it is built around is Sodium Hyaluronate, named eighth on its own ingredient list. The same list carries Niacinamide, Adenosine and Ascorbyl Propyl Hyaluronate, 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 essence format rather than by the list alone. This is the Original Korean Formula, the essence Isntree sells in Korea, Sodium Hyaluronate and all.
Key benefits
- Sodium Hyaluronate, the humectant this essence is built around
- Niacinamide and Adenosine on the same list, actives
- Ascorbyl Propyl Hyaluronate on the same list, an antioxidant
- Beta-Glucan on the same list, a polysaccharide
- Avena Sativa (Oat) Kernel Extract and Pteris Multifida Extract further down the same list
- Cynara Scolymus (Artichoke) Leaf Extract and Polyglycerin-3 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. The name on the box points at it, and it is named eighth on this essence's own ingredient list.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. The panel names it seventh on this essence's list, beside Sodium Hyaluronate.
Adenosineactive
Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated. The panel names it thirty-first on this essence's list, beside Sodium Hyaluronate.
Ascorbyl Propyl Hyaluronateantioxidant
Vitamin C bound to hyaluronic acid, which keeps it stable and brings its water-holding with it. It is a mild, water-soluble route to a vitamin C formula. It is named eighteenth on this essence's list, alongside Sodium Hyaluronate.
Beta-Glucanpolysaccharide
Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin. The panel names it thirtieth on this essence's list, beside Sodium Hyaluronate.
Isntree Hyaluronic Acid Water Essence
Where does this essence go in my routine?
After toner and before serum, morning and evening, on damp skin. Anything thinner than an essence goes on before it, and anything richer goes on after. 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 essence or a US version?
The Korean-market one, Sodium Hyaluronate and all. We match this essence to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Sodium Hyaluronate?
Niacinamide, Adenosine and Ascorbyl Propyl Hyaluronate. The order they are printed in on this essence's panel is the order on the box, so you can see where Sodium Hyaluronate sits relative to them. Further down the same panel: Beta-Glucan, Avena Sativa (Oat) Kernel Extract and Pteris Multifida Extract.

How to use
- Use the Hyaluronic Acid Water Essence after toner and before serum, morning and evening, on damp skin.
- A small palmful, pressed over the face and neck in two passes rather than rubbed in.
- Toner first, this second, then your serum and moisturizer. It is the layer that thins the ground so the step above it spreads instead of sitting.
- Twice a day, every day. Do not use it in place of your moisturizer; an essence is a water layer, not the lid on top of one.
Worth knowing
- Patch test this essence on a small area and wait a day before using it more widely, especially with Sodium Hyaluronate on the list.
- Introduce this essence on its own for the first week, so anything your skin does is traceable to the Sodium Hyaluronate rather than to three changes at once.

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

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
