What it is

Five molecular weights of hyaluronic at 2.0%, with polyglutamic acid to stop it drying tight and ectoin to keep it stable. Different weights sit at different depths, which is the entire reason to use more than one.

First thing after cleansing, onto damp skin. Everything you apply next moves through it.

What’s inside

Every active, and what it is doing there.

The number on the bottle is a position on a scale. This is what sits behind it.

  • ACTIVE

    Hyaluronic acid, five weights 2.0%

    Different molecular weights sit at different depths. That is the entire reason to use more than one.

  • ACTIVE

    Hyaluronic acid 2.0%

    A humectant that holds water at the surface.

  • SUPPORTING

    Polyglutamic acid

    A humectant used alongside hyaluronic so it does not dry down tight.

  • SUPPORTING

    Ectoin

    An extremophile-derived osmolyte used for comfort under environmental stress.

These are the actives and the supporting ingredients we formulate around. The complete INCI list is being added to every product page.

Plumper is the right word

I put it on damp skin and everything after it works better. It has become the step I would not skip.

For the price this is the best value thing in the range, I think

It goes into everything.

Sinead Q.
4.0

Very nice hydrating layer

It is subtle — do not expect a dramatic result, expect everything else to sit better.

Ruth E. Verified buyer
4.0

Good product, and I like that it is honest about being a water layer rather than pretending to be a treatment.

Priyanka M. Verified buyer
5.0

Weightless, absorbs instantly, no tackiness at all

Layers under sunscreen with zero pilling.

Ahmed I. Verified buyer

Dehydrated skin from flying twice a week

This fixed the tightness within days.

Questions

Frequently asked

Common questions about the water serum

What does the colour on the bottle mean?

It is the dose. Every product floods one of five steps of the same blue: the palest is the cleansers, where water does the work, and full-strength cupric is reserved for the four copper products. A product cannot change band because of a season or a repackage.

Why is copper limited to four products?

Because a flagship that can be extended forever is not a flagship. GHK-Cu at full dose is the most expensive thing we make and it stays on the face, in four products. If we launch a fifth copper SKU, we will have changed our minds in public rather than quietly.

Do you publish the percentages?

On every product, in the first chapter of the page, before any claim is made about it. Where a formula is a blend rather than a single active, the page shows the blend instead of inventing a headline number.

How do I know what not to layer?

It is printed in the how-to-use block on each product, not buried in an FAQ. The short version: copper peptides and direct acids do not go on together, and a retinal night is followed by SPF in the morning.

Where do I start?

The copper protocol — the blue serum, the barrier cream and the daily spf. Treat, repair-adjacent support, and protection, which is the whole argument of the system in three steps.

Before you buy

The number is a position, not a grade.

Every active at the percentage it is used at, and what not to layer it with — stated before any claim is made about it.
