Helloskin vs PeptiClinic
PeptiClinic's Copper Peptide + KPV Repair Serum pairs GHK-Cu with KPV — a genuine anti-inflammatory tripeptide we don't carry, and a real point of difference. Credit for that. But the page publishes no full ingredient list and no percentages for either peptide, so there's no way to know how much of anything you're getting. We declare a full 9% peptide system, every dose, on a complete 16-ingredient label, scored 9.6/10 on a ChatGPT ingredient scan. Here's the breakdown — no spin, just chemistry.
A genuine repair peptide in KPV — but paired with GHK-Cu at doses the page never states, on a label it doesn't fully publish.
The two formulas, side by side.
Every spec that matters — including KPV, the repair peptide PeptiClinic genuinely has and we don't.
A repair peptide, or a declared system?
KPV (Lys-Pro-Val) is the real story here — a short peptide with genuine anti-inflammatory, barrier-calming interest that we don't offer. That's a fair reason to like this serum. The catch is that neither KPV nor the GHK-Cu comes with a percentage, and there's no full INCI to place them.
peptide doses disclosed
GHK-Cu and KPV are both named, and KPV is a genuinely interesting repair peptide. But no percentage is given for either, and the page doesn't publish a full ingredient list — so you can't tell how much of either you're applying.
every peptide declared
1.2% GHK-Cu + 5% Palmitoyl Tripeptide-1 + 3% Palmitoyl Tetrapeptide-7 — Matrixyl 3000 — all declared, antioxidant-protected, on a full 16-ingredient label.
Credit where it's due: KPV is a real anti-inflammatory peptide we don't carry, and if calming is your priority it's a genuine draw. But for a serum sold on copper peptide, undisclosed doses and a partial label tell you less than a fully-declared system.
What's on the record.
You can only judge the doses a brand publishes. Here's what each label actually declares.
PeptiClinic genuinely offers a peptide we don't — KPV — and that's worth real credit. But two named peptides at undisclosed doses, on a page without a full INCI, is a smaller, less verifiable formula than a declared 9% system on a complete label.
We ran our formula through a ChatGPT ingredient scan.
The prompt: "Scan this like a shopper comparing GHK-Cu serums, using the INCI list and confirmed peptide percentages." Because every dose is declared, there's something real to score.
"A genuinely serious copper peptide serum"
In its words: "not one where the peptides are buried at tiny marketing levels — with 1.2% verified GHK-Cu and 9% total peptides, this sits in a genuinely premium performance category."

All 15 categories. Scored fairly.
Helloskin wins 11, ties 2, cedes 2. PeptiClinic genuinely wins on its KPV repair peptide and its headline price. Credit where it's due.
Every ingredient. Both labels, side by side.
We publish all 16 ingredients and every peptide dose. PeptiClinic names its two peptides but doesn't publish a full INCI or any percentages.
What PeptiClinic gets right.
There's a real idea here. KPV — Lys-Pro-Val — is a genuinely interesting peptide with anti-inflammatory and barrier-calming research behind it, and it's one we don't carry. Pairing it with GHK-Cu is a thoughtful combination for reactive or compromised skin, the serum is a stated 30ml dispatched from an Australian facility, and at $64.90 it undercuts us on price. If a calming, repair-focused peptide is your priority, that's a legitimate reason to choose it.
Where we pull ahead is disclosure and completeness. Neither GHK-Cu nor KPV comes with a percentage, and the page doesn't publish a full ingredient list, so you can't tell how much of either peptide you're getting or what else is in the bottle. There's no Matrixyl for collagen support, and no stated antioxidant to protect a copper peptide that oxidises. We publish a 9% peptide system to the decimal on a full 16-ingredient label, add Niacinamide and Tocopherol, and tell you it's 30ml. A repair peptide is a real plus; a dose you can trust is the foundation.
