What it is

Tranexamic acid at 3.0% with azelaic at 10% and niacinamide at 4.0% — three well-understood tone actives at strengths you can look up, rather than one at a strength you cannot.

Nights only. Keep it away from the copper products: use one on alternate evenings rather than stacking them and hoping.

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

    Tranexamic acid 3.0%

    A tone active used for the look of marks and uneven patches.

  • SUPPORTING

    Azelaic acid 10%

    A dicarboxylic acid used for the appearance of tone, texture and redness.

  • SUPPORTING

    Vitamin B3 4.0%

    Used for the look of pores, tone and barrier comfort. One of the few actives that plays well with almost everything.

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

Melasma on my upper lip that I have had since my second pregnancy. After about ten weeks it is genuinely lighter. Not gone, lighter, and I was told to expect exactly that.

Even tone is the thing I care about most and this is the first product that has actually moved it.

Petra Z. Verified buyer
4.0

Good results, slight sting for the first week on freshly cleansed skin. Applying to slightly damp skin fixed it. Worth knowing going in.

Mo H. Verified buyer
4.0

Expensive, and I did have to be patient

At week four I was ready to give up. At week nine I was recommending it to my sister.

Grace O.
5.0

Sensitive skin, no irritation at all, and my cheeks are visibly less blotchy. I use it every other night.

Lucia F. Verified buyer
5.0

Old acne marks on my jaw have faded more in three months than in the two years before it. The azelaic dose being printed on the front is why I bought it.

Kelly T. Verified buyer
5.0

No pilling under sunscreen, which is rare for anything with this much active in it. Texture is thin and sinks in fast.

Anneke J. Verified buyer
3.0

Fine product but it was not the right one for me — my pigmentation is sun damage rather than post-inflammatory and I think I needed something else. Support were straight with me about that when I asked, which I respected.

Questions

Frequently asked

Common questions about the bright 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.
