How it works

The Hydrium Watery Toner is a 280ml toner, used straight after cleansing, morning and evening, while the face is still damp. The active it is built around is Allantoin, named fifth on its own ingredient list. The same list carries Panthenol, Sodium Hyaluronate and Hydrolyzed Hyaluronic Acid, so the active is not the only thing on it worth naming. How much of the Allantoin stays on the skin, and for how long, is decided by the toner format rather than by the list alone. COSRX sells this Allantoin toner in Korea, and this is that version.

Key benefits

  • Allantoin: a soothing, skin-conditioning agent
  • Panthenol: pro-vitamin B5, carried for softness and moisture
  • Sodium Hyaluronate: a low-weight form of hyaluronic acid, for surface hydration
  • Hydrolyzed Hyaluronic Acid: the catalogue's most common humectant, for water retention
  • Opens with Water, Butylene Glycol, Glycerin, 1,2-Hexanediol and Allantoin, the ingredients COSRX put first
  • No fragrance or parfum on the ingredient list

Key actives

5Allantoinactive

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. On this toner's own ingredient list it is named fifth.

All products with Allantoin

6Panthenolhumectant

Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh. The panel names it sixth on this toner's list, beside Allantoin.

All products with Panthenol

7Sodium 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 named seventh on this toner's list, alongside Allantoin.

All products with Sodium Hyaluronate

10Hydrolyzed Hyaluronic Acidhumectant

Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one. It is named tenth on this toner's list, alongside Allantoin.

All products with Hydrolyzed Hyaluronic Acid

11Hyaluronic Acidhumectant

Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there. The panel names it eleventh on this toner's list, beside Allantoin.

How to use

  1. Use the Hydrium Watery Toner straight after cleansing, morning and evening, while the face is still damp.
  2. Pour a coin-sized pool into your palms and press it over the face in two passes rather than dragging it around with a cotton pad.
  3. It goes on before serum and moisturizer, and the damp layer it leaves is what the step above it holds on to.
  4. Twice a day, every day. Do not let it dry down completely before the next layer goes on, or you lose the reason for applying it to damp skin.

What professionals say

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

  • Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

    Wilma Bergfeld, MDDermatologist, Cleveland Clinic
  • Pantothenol is a common ingredient in skin care and hair products I recommend, particularly for people who are prone to dryness.

    Taylor Bullock, MDDermatology resident, Cleveland Clinic

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