Every product is one step on the same dilution. Palest where water does the work, full strength where the copper does. The colour on the bottle is the dose.

Every active in the range is declared at the percentage it is used at, on the page, before any claim is made about it. If a formula is a blend, the page shows the blend.

order matters more than quantity.

Four steps used properly beat nine used hopefully. This is the order things go on, and the hours they belong to.

GHK-Cu at full dose is the most expensive thing we make. A flagship that can be extended forever is not a flagship, so it is capped — and if we ever launch a fifth, we will have changed our minds in public.

The other capped system is the shield — every SPF in the range, on one band: the midday spf, the daily spf, the tinted spf.

the blue serum, the barrier cream and the daily spf — treat, support, protect. The whole argument in three steps. Everything else in the range is a refinement of these.

Nothing here is a rescue.

Skin is not a problem to be solved on a deadline. It is a system to be supplied — at a stated dose, in a stated order, for as long as you keep showing up. We sell the compounds, print the numbers, and tell you what not to layer them with. The rest is just doing it on a Tuesday.

FAQ

Questions, answered.

The essentials people ask before their first order.

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.
