Influences thousands of genes

GHK-Cu changed the expression of over 4,000 human genes, pushing skin cells toward a repair state.

Supports the skin's own collagen

Research on GHK-Cu shows it stimulates collagen, elastin and the molecules that hold water in the skin. Your body's own level drops by about 60% between age 20 and 60.

The science behind the serum.

What skin runs low on with age, and what a few drops of copper peptide do about it.

GHK-Cu Peptide Serum

A copper peptide signal, in a few drops.

Lines

Why it happens

Skin makes less collagen with age and holds less water. Lines that used to go away after sleep start to stay.

How the formula helps

GHK-Cu is a copper peptide your body makes less of with age. Research on GHK-Cu shows it signals skin to support its own collagen. A few drops a day add that signal to your routine, so lines look softer over the weeks.

Research on GHK-Cu used other formulas. This serum was not tested in those studies.

6 ingredients. 1 signal.

Water, a copper peptide, hyaluronic acid and three helpers. Nothing else.

GHK-Cu copper peptide
The signal

GHK-Cu copper peptide

A clinically proven copper peptide your body makes less of with age. Research on GHK-Cu shows it signals skin to support its own collagen.

Hyaluronic acid
Holds water

Hyaluronic acid

Holds water in the skin so it feels smooth and comfortable while the signal does its work.

Pentylene glycol
Carries it in

Pentylene glycol

A light carrier that helps the formula spread and absorb without a sticky feel.

Phenylpropanol
Keeps it fresh

Phenylpropanol

Keeps the bottle fresh. The formula has no fragrance and no acids.

Sodium hydroxide
Balanced

Sodium hydroxide

A tiny amount that sets the pH so the copper peptide stays stable and the serum does not sting.

THE MECHANISM

The signal got quieter.

Most creams only moisturise the surface. Your body's own copper peptide drops by about 60% between age 20 and 60. This adds a copper peptide signal to your routine, and research on GHK-Cu shows it signals skin to support its own collagen.

WHY THIS MATTERS

Tired is not the same as old.

GHK-Cu copper peptide signalling in the skin: cell signalling, skin repair, barrier support
HOW TO USE

A few drops. Once or twice a day.

Morning, evening or both. No peeling.

01

Clean, dry skin

Wash, pat dry, 3 to 4 drops where the lines are.

02

Massage in

Rub in until it is gone. No smell, no residue. Then your normal moisturiser.

03

Every day for 90 days

Smoother by week 2 to 3. Lines look softer from week 6. Judge it at 90 days.

Using tretinoin or retinol? Copper peptide in the morning, retinoid at night. Vitamin C in a different step.

THE 90 DAY PROTOCOL

Reset your skin signaling.

Skin feels smoother before it looks different. Lines soften slowly, so slowly that you may not see it in the mirror. A photo on day 1 and day 90, same spot, same window, shows it. Most people say someone else noticed first.

Start your 90 days
DEEP DIVE

GHK-Cu signalling science.

Glycyl-L-Histidyl-L-Lysine Copper is a tripeptide your body makes. It binds copper ions and acts as a messenger to fibroblasts, the cells that build skin structure. It is naturally present in the body and drops by about 60% between age 20 and 60, which is one reason repair slows down. Applied to the skin, it adds that signal to your routine.
GHK-Cu balances the enzymes that break tissue down (MMPs) and the ones that hold it back (TIMPs). That balance lets skin clear out old, disorganised collagen instead of piling new tissue on top of it. It also lowers the inflammatory signals that make skin look tired and uneven.
Research by Loren Pickart shows GHK-Cu influences gene expression for repair of the skin's support structure. Cells rebuild collagen (Type I and III), elastin and the molecules that hold water in the dermis. Lines look softer, texture evens out and skin looks firmer. That is the 90 day protocol.

3 bottles come with the tool that helps it work faster.

The 3 bottle protocol ships with a dermaroller. Its tiny needles open microchannels in the skin so more of the peptide gets in instead of sitting on top. Roll twice a week on clean, dry skin, apply the serum straight after, rinse the roller.

The roller is optional: the serum works on its own. Serum plus roller gets you to the first visible change faster, and the third bottle covers the full 90 days.

Why 3 bottles

Skin feels smoother in weeks. Lines soften over months. One bottle shows you it works. Three bottles cover the full 90 days. Select your supply in the buy box.

WHAT CHANGES, AND WHEN

The 90 day timeline.

Skin feels more balanced and comfortable. Nothing dramatic yet. The signal is being received.
Tone looks more even. It can look a little worse before it looks better. That is normal, and it passes.
Collagen is being supported under the surface and skin looks firmer week by week. This is usually the first moment someone else notices.
Same spot, same window as day 1, and compare. Most people keep going with a few drops every other day.

A few drops a day, against the alternatives.

Keep it simple. Or add the infusion kit.

Use the serum on its own, or pair it with the Peptide Infusion Kit on the nights you roll.

The second step, explained

Why pair it with the infusion kit?

The serum adds the signal. The infusion kit carries collagen peptides to this layer.

  • 1The serum is the daily step. A few drops every morning, a copper peptide signal every day.
  • 2The infusion kit carries collagen peptides under the surface, 3 nights a week. Apply the serum straight after rolling, when skin takes in the most.
  • 3Two products. Still simple. No serums, no layering, no ten step routine.

Frequently asked questions.

Most people feel smoother skin within 2 to 3 weeks. Lines look softer and tone more even from week 6 to 8. Judge it at 90 days.
Yes. The formula is fragrance free, non comedogenic and suitable for all skin types, including sensitive skin and skin that breaks out easily. If your skin is very reactive, start every other day for the first week.
No. The blue colour is the copper peptide bond itself. It absorbs fully into the skin within a minute and leaves no tint, residue or smell.
Yes, just not in the same step. Strong acids and vitamin C can break the copper bond if layered at the same moment. Use GHK-Cu in the morning and tretinoin or acids at night. Apply to clean skin, follow with moisturiser. This matters more after 40, when most people already use a retinoid.
Some people see a few weeks where skin looks slightly duller or looser. It is old collagen being cleared before new collagen is built. It passes. Stay consistent.
No. The serum works on its own. The roller opens microchannels so more of the peptide gets in. It comes free with 3 bottles and is optional.
Concentration and delivery. Drugstore serums use sub 1% peptide solutions in a tacky base. This is a 97% purity GHK-Cu in a pH stabilised vehicle built for absorption. You are paying for the signal, not for surface hydration.
One bottle is enough to see it work at 3 to 4 drops a day. 3 bottles cover the full 90 days and the months after.
No results after 90 days? Full refund. Email us and we refund you in full. Keep the bottle.
All orders are processed within 1 to 2 business days. Delivery typically takes 2 to 5 business days depending on your location. Tracking is emailed as soon as the package leaves the warehouse. Shipping is free on every order.
Water, Pentylene Glycol, Sodium Hyaluronate, Copper Tripeptide-1, Phenylpropanol, Sodium Hydroxide. Hyaluronic acid keeps your skin hydrated. Copper Tripeptide-1 signals your skin to repair and rebuild. The rest stabilises the formula and ensures full absorption. 30 ml.
