GHK-Cu copper peptide, finally delivered past the barrier.

GHK-Cu is one of the most studied regenerative peptides in human plasma — and it cannot cross the skin or scalp barrier on its own. Most of what you have rubbed on never reached the target. PeptideScience builds the delivery first: a dissolving microneedle patch for wrinkles and a scalp micro-infusion kit for menopausal thinning.

The molecule

What is GHK-Cu copper peptide, and why does it matter after 35?

GHK-Cu is a small tripeptide bound to a copper ion. Your body makes it, and your plasma levels fall sharply between your twenties and your sixties. In published studies it signals the skin to build new collagen, grows the tiny blood vessels that feed tissue, and calms the inflammation that ages both skin and scalp.

That is why it appears in serious skin care and in hair-growth research alike. The catch is size and chemistry: at 340.4 daltons and water-loving, GHK-Cu cannot pass the oily outer barrier of the skin, and it cannot get through the calcified build-up a lifetime of hard water leaves on the scalp. Rubbed on, most of it never gets in.

PeptideScience exists to solve the second half of that sentence. Read how we build.

How PeptideScience gets copper peptide past the skin and scalp barrier

FORMULA PS-01 · FACE

A dissolving microneedle patch for wrinkles

One sealed patch a night on clean, dry skin: under the eyes, between the brows, along the mouth. Press for five seconds. Your body heat melts the ~2,600 crystallised cones, releasing GHK-Cu and hyaluronic acid below the outer layer that stopped every serum you own. In the morning it lifts away clean. See the patch step by step.

FORMULA PS-02 · SCALP

A scalp micro-infusion kit for menopausal thinning

Press the clear vertical stamp gently along your hairline, part and crown for thirty seconds. It opens thousands of 0.25 mm channels through the scalp shield — straight down, never rolled, so it does not tear tissue or catch hair. Then the GHK-Cu ampoule goes on and reaches the root with up to 400% more serum than rubbing it in. Twice a week. See the kit step by step.

The honest timeline

What to expect — including the weeks when nothing seems to happen

  • Days 1–14Skin looks fuller the first morning (that is the hyaluronic acid, not the peptide yet). On the scalp, a cooling tingle after each stamp.
  • Weeks 2–8Redness settles and rebuilding starts under the surface. Shower-drain shedding slows. This is the stretch most women quit in — the guarantee covers it on purpose.
  • Weeks 8–16Lines are shallower because collagen has been rebuilt, not puffed up with water. Fine new growth shows along the part and hairline.
How we build

Three rules we do not break.

01

We refused to dye it blue

GHK-Cu is faintly blue in solution, and counterfeit serums are deliberately dyed blue to imitate it. Ours is undyed. If the colour is the proof, the proof can be bought in a bottle of pigment.

02

Delivery is the product

A peptide that cannot reach the dermal papilla is a peptide you paid for and never received. Every product we make is a delivery system first and a formula second.

03

Specification over adjectives

Concentration in ppm, the molecule’s weight, a LOT number that ties the unit to its batch. Numbers you can check instead of language you cannot.

Honest answers

GHK-Cu copper peptide questions, answered

What is GHK-Cu copper peptide?

GHK-Cu is a tripeptide (glycyl-L-histidyl-L-lysine) bound to a copper ion. It occurs naturally in human plasma and declines with age. In studies it supports collagen production, blood-vessel growth and tissue remodeling — which is why it appears in both skin and scalp care.

Why do most copper peptide serums not work?

GHK-Cu weighs 340.4 daltons and is water-loving, so it cannot pass the oily outer skin barrier or the calcified layer on a hard-water scalp. Rubbed on, most of it stays on the surface and is washed off. PeptideScience products are delivery systems first: the patch dissolves micro-cones past the skin barrier; the kit opens 0.25 mm channels through the scalp shield before the ampoule goes on.

Which PeptideScience product is right for me?

Fine lines, crepiness or loss of firmness on the face: FORMULA PS-01 Peptide Wrinkle Activator (overnight patch). A widening part, thinning at the crown or hairline linked to menopause: FORMULA PS-02 Peptide Root Activator (scalp stamp + ampoules). Many women use both.

Is the microneedle patch or scalp stamp painful?

No. The PS-01 patch uses crystallised cones you cannot feel that dissolve overnight. The PS-02 stamp presses straight down — never rolls — so it does not slice tissue or catch hair. Most women describe a light cooling tingle.

Is it hormone-free and drug-free?

Yes. Nothing in either product enters the bloodstream. There are no hormones, no minoxidil and no acids. Read the Medical Disclaimer and patch-test first if you have sensitive skin.

What is the guarantee?

FORMULA PS-01 is covered for 100 days and FORMULA PS-02 for 120 days — long enough to see the skin and hair growth cycles through. If you are not satisfied, contact us for a refund. Full terms are on the Returns & Refunds page.
