Retinol asks for a month
Flaking, tightness, a purge you have to schedule around. Plenty of people quit in week three and never find out whether it would have worked.
GHK-Cu Copper Peptides
Firm, hydrate
& renew.
A two-step copper peptide system. The serum delivers GHK-Cu on a triple-weight hyaluronic acid base; the booster cream seals it in with squalane and ceramides. Fragrance-free, no sting, no purge.

Why Copper Peptides
The active for people retinol didn't suit.
Most anti-aging routines ask you to trade comfort for results. Copper peptides were formulated around the opposite premise.
Ten-step routines collapse
Anything that takes fifteen minutes gets skipped on a Tuesday. Two steps that take sixty seconds get done every night — and consistency is the variable that actually matters.
Fragrance is the usual culprit
If a product has ever made your skin feel hot or itchy, fragrance and essential oils were the likeliest cause. Neither is in this formula.
The System
Two steps. One peptide.
Buy them separately, or take the duo and save $10. Same GHK-Cu in both — the serum delivers it, the cream keeps it there.
Copper Peptide Serum
Step 01 · 30 ml
GHK-Cu suspended in a triple-weight hyaluronic acid base. Absorbs in seconds, layers under anything, leaves no film.
- Best for texture and hydration first
- Layers under any moisturiser you own

What is GHK-Cu?
A three–amino-acid peptide bound to a copper ion — one of the most-studied peptides in cosmetic chemistry.
01
Naturally occurring
GHK is a tripeptide found in human plasma. Levels are highest in your twenties and decline with age — which is exactly why it became a fixture in topical formulation.
02
Copper is the point
The peptide's affinity for copper gives the finished serum its signature blue tint. That colour isn't dye — it's the complex itself, and it's how you know it's in there.
03
No purge, no peel
Unlike retinoids, copper peptides are well tolerated from the first application. No adjustment period, no flaking, no building frequency over six weeks.
Anti-Aging
Looks firmer where it's gone slack.
The places that soften first — along the jaw, under the eyes, across the front of the neck. Copper peptides are the anti-aging active for people who can't tolerate a retinoid, or don't want to spend a month peeling to get there.
- Targets the appearance of fine lines and crepiness
- Supports a firmer, more resilient-looking surface
- Layers safely with retinol on alternate nights
Hydrating
Plump, not shiny.
Three molecular weights of hyaluronic acid in the serum draw water into the surface; squalane and ceramide NP in the cream stop it evaporating back out. That combination is why skin looks cushioned by morning instead of tight.
- Triple-weight hyaluronic acid plus glycerin
- Ceramide NP and squalane support the moisture barrier
- Non-comedogenic, no silicones, no fragrance
Texture
Smoother under your fingertips.
Rough patches, the grainy feel across the cheeks, pores that read larger than they are. Texture is the first thing most people notice changing — it's a surface-level result, and it shows up in how your makeup sits before it shows up anywhere else.
- Refines the look of uneven surface texture
- Minimises the appearance of enlarged pores
- Gives foundation a smoother base to sit on
Brightening
A more even-looking tone.
Not bleaching — evening. The goal is that dark patches, old marks and general dullness stop being the first thing you see. Works alongside vitamin C, provided you use them at opposite ends of the day.
- Helps the look of uneven tone and lingering marks
- Restores a healthier-looking radiance to dull skin
- Use PM; save your vitamin C for AM

How to Use
Sixty seconds, twice a day.
Copper peptides are low-maintenance. There's no ramp-up schedule and nothing to build tolerance to.
01
Cleanse
Start on clean skin, still slightly damp. Damp skin gives the hyaluronic acid something to pull from.
02
Serum
Three to four drops. Press — don't rub — across face, under the eyes and down the neck. Wait thirty seconds.
03
Booster Cream
A pea-sized amount over the top, morning and night. Follow with SPF in the AM.
A note on layering: keep copper peptides and direct vitamin C in separate routines — AM for one, PM for the other. Retinol is fine, just on alternate nights while you settle in.

The Guarantee
Use the whole bottle. Then decide.
Copper peptides need eight to twelve weeks before you can fairly judge them, so a two-week return window would be pointless. Take sixty days. If it isn't for you, email us for a full refund — keep the empty bottle, nothing to ship back.
Questions
Before you buy.
How long until I see something?
Hydration and surface smoothness are usually the first things people notice, within the first week or two. Anything to do with firmness and the look of fine lines is a longer game — give it a full eight to twelve weeks of consistent twice-daily use before you judge it. Individual results vary.
Can I use this with retinol?
Yes, but ease into it. Alternate nights for the first few weeks — retinol one night, copper peptides the next. Once your skin is settled, plenty of people layer copper peptide serum underneath their retinoid without issue.
What about vitamin C?
Keep them separated by time of day. Direct L-ascorbic acid and copper peptides don't play well in the same application, so run vitamin C in the morning and copper peptides at night — you get both, neither cancels the other.
Why is the serum blue?
That's the copper-peptide complex itself, not added colour. It's a useful signal — a copper peptide serum that's completely clear is worth asking questions about. The blue does not stain skin or bedding.
Do I need both the serum and the cream?
The serum on its own works. The cream exists because a water-based serum evaporates off the surface faster than you'd like, and sealing it in meaningfully changes how skin looks by morning. If you already use a moisturiser you love, start with the serum and add the cream later.
Is it safe for sensitive skin?
It's formulated for it — fragrance-free, no essential oils, no denatured alcohol. Copper peptides are among the better-tolerated actives. Patch test on the inner forearm for 24 hours first if you react easily.
What's the guarantee?
Sixty days, empty bottle included. Use the whole thing, and if it isn't for you, email us for a full refund. You don't need to send anything back.
