How it works
The panel on this serum names six forms of hyaluronic acid rather than one: Sodium Hyaluronate, Sodium Hyaluronate Crosspolymer, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Sodium Hyaluronate, Hydrolyzed 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.
Key benefits
- Six forms of hyaluronic acid on one panel, not a single token inclusion
- 30 ml to a unit
- Korean GS1 barcode matched against a Korea sourcing supplier's record for this item
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.
Sodium Hyaluronate Crosspolymer
Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
Hydrolyzed Hyaluronic Acid
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.
Hyaluronic Acid
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.
What does Sodium Hyaluronate do in this serum?
Sodium Hyaluronate sits within the first ten ingredients, one of this formula's moisture-binding hyaluronate forms.
Is Sodium Hyaluronate Crosspolymer also in this formula?
Sodium Hyaluronate Crosspolymer sits within the first ten ingredients, one of several distinct hyaluronate forms this formula layers rather than relying on a single one. It sits alongside Sodium Hyaluronate on Mary & May's ingredient list for this product.
How is this serum used in a routine?
Apply a few drops to cleansed skin and pat in gently before moisturiser. It works as a treatment step layered under moisturiser.
Who is this serum suited for?
Normal skin, Dry or dehydrated skin are the best fit for this serum. Patch test on the inner arm before first full use, as with any new skincare product.

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