How it works

Sodium Hyaluronate leads the ingredient panel on this serum. 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. On this panel it sits alongside Niacinamide, Adenosine and Ceramide NP. Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Key actives

Sodium Hyaluronate

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.

Niacinamide

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.

Adenosine

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.

Ceramide NP

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.

Payment and security

We accept

How to use

  1. Apply after toner while the skin is still damp, since humectants work best on a wet surface.
  2. Press three or four drops across the face with flat fingertips rather than rubbing.
  3. Always follow with a moisturiser, because a humectant serum alone can leave dry skin tighter.
  4. Do not apply it to bone dry skin in a dry room, as that is when a hydrating serum feels worst.

Worth knowing

  • Patch test on the inner arm before first full use, as with any new skincare product.

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.

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

    Samantha Stein, PA-CDermatology physician assistant, Cleveland Clinic
  • Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.

  • 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.
