Skin³

The copper peptide that holds.

For the decade your skin starts changing. One serum, three peptide technologies — kept stable, so the slow work of repair actually lasts.

Peptides work slowly. Give it about 90 days — that’s the honest timeline. We’ll check in around then to see how it’s going.

01 the Hold

Most copper peptides fall apart. This one holds.

Copper peptides are famously unstable. They oxidise and break down — often before they ever reach your skin. The Hold is how we keep ours intact: stable in the bottle, stable on your face, free to do the slow work of repair.

It’s the one thing an INCI list can’t tell you. Two serums can read identically and behave nothing alike. Stability is the difference — and it’s the part we built the product around.

We’re honest about the slow part too: copper peptides take time, and they won’t do the job of sunscreen or a retinoid. They do one thing well — repair that holds.

02 what’s inside

Read the receipts.

No hidden numbers. Every active at its real concentration — and what it does, in plain language.

R-01 — copper tripeptide-1

ghk-cu 1.11%

The original copper peptide. Signals skin to repair and rebuild — the slow, well-studied workhorse.

R-02 — expression-line peptide

acetyl hexapeptide-8 5%

Softens the look of expression lines over time. Gentle and gradual — no freeze, no force.

R-03 — matrix peptide

matrixyl 3000 3%

A peptide duo that supports the skin’s own matrix — playing the long game alongside ghk-cu.

R-04 — vehicle

the base q.s.

Glycerin and low-irritant humectants. No fragrance, no essential oils. Barrier first — for skin that’s done with harsh.

What it won’t do. It won’t work overnight, and it won’t replace your sunscreen or your retinoid. We’d rather say so. It does one thing well: repair that holds.

03 the ritual

The nightly ritual.

A practice for the decade, not a chore. Three things to know.

01

When

At night, on clean skin. One pump, pressed in before your moisturiser. That’s it.

02

With what

Plays well with most routines. Keep strong acids and high-strength vitamin C to other nights at first — your barrier will thank you.

03

How long

About 90 days to judge it fairly. Skin tends to feel different before it looks different.

The straight answer on layering. Wondering if it clashes with your vitamin C or your acids? Fair question — most advice is vague here. The honest version: separate them at first, give your skin a week or two, then see how it does. Sensitive? Buffer with moisturiser. No drama.

04 the 90 days

The honest timeline.

We’d rather tell you than sell you a “fast” that isn’t real.

One pump at night. We set the expectation, not the hype.

05 straight answers

The questions, answered.

Honestly? About 90 days. Peptides are slow. Skin often feels different in the first few weeks; visible change takes longer. We check in around day 90 to see how it’s going.

Yes — with a little spacing at first. Keep strong acids and high-strength vitamin C to other nights for a couple of weeks, then see how your skin does. If you’re sensitive, buffer with moisturiser.

Yes. No added fragrance, no essential oils. Barrier first — it’s made for skin that’s done with harsh.

Our name for how we keep the copper peptides stable — intact in the bottle and on your skin, instead of breaking down before they work. It’s the difference you can’t read off an ingredient list.

Our subscription, built around your routine rather than a warehouse schedule. A bottle every 60 days, which is roughly how long one lasts. Pause or leave any time — no games.

Copper peptides are generally considered gentle, but everyone’s different — check with your doctor about your specific routine. We don’t make medical claims.
