What it is

Retinaldehyde at 0.10%, double the night retinal. Move here when the lower strength has stopped being interesting, not before, and not because it costs the same.

Nights, and SPF the next morning. A peptide complex and squalane keep it civil.

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

    Retinal 0.10%

    A vitamin A derivative one conversion step from retinoic acid, which is why it works at a lower number than retinol.

  • SUPPORTING

    Peptide complex

    A blend of short chains supporting the look of firmness.

  • SUPPORTING

    Squalane

    A stable, light emollient that softens without a heavy finish.

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

Moved up from the standard one after about four months and there was no adjustment period at all. Charging the same price for the higher strength is a genuinely unusual thing to do and I noticed.

Very good, slightly richer than I want in July

Winter product for me.

Kwame B. Verified buyer
5.0

Same texture, same finish, more of it

Exactly what I wanted from a step up. No purging.

Bruno A. Verified buyer
5.0

Deeper lines on my forehead are the thing I was after and they are softer. Took about ten weeks.

Charlie N. Verified buyer
5.0

I appreciate that the site tells you to start on the lower one

A lot of brands would just sell you the strong one first.

This one I do have to be careful with — three nights a week is my limit or my cheeks get tight. The lower strength was fine every night. Know your own skin.

Questions

Frequently asked

Common questions about the stronger retinal

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
