Helloskin vs NXTGEN Labs
On the surface NXTGEN Labs looks close — same $89.99, same 30ml, also made in Australia, Niacinamide high on the list. Fair enough. But that's where it ends: it's a single copper peptide at an undisclosed dose, sitting ninth on the label just after the preservative, with no Matrixyl and no antioxidant to protect the copper. We put a fully-declared 9% peptide system — 1.2% GHK-Cu plus Matrixyl 3000 — in the same-priced bottle, scored 9.6/10 on a ChatGPT ingredient scan. Here's the breakdown — no spin, just chemistry.
Same price, same size, also Australian — but one copper peptide at a dose they won't name, and no Matrixyl behind it.
The two formulas, side by side.
Every spec that matters — including the rows where NXTGEN Labs matches or beats us. This is the closest comparison we've run.
One peptide, or a declared system?
NXTGEN Labs matches us on the surface — same price, Australian-made, Niacinamide high on the list. The gap is everything underneath: one copper peptide at a dose they don't disclose, sitting ninth after the preservative, versus a declared three-peptide system with Matrixyl 3000.
at an undisclosed dose
Copper Tripeptide-1 is the only peptide, and it sits ninth on the label — just after Sodium Benzoate, the preservative — with no percentage stated. No Matrixyl, and no antioxidant to protect a copper peptide that oxidises.
declared, across three peptides
1.2% GHK-Cu + 5% Palmitoyl Tripeptide-1 + 3% Palmitoyl Tetrapeptide-7 — Matrixyl 3000 — every dose on the label, antioxidant-protected, in a stated 30ml.
Credit where it's due on price, origin and Niacinamide. But for a serum sold on GHK-Cu, an undisclosed single peptide with no Matrixyl behind it tells you a lot less than a fully-declared 9% system.
What each label puts on the record.
Both brands publish a full INCI — but only one publishes the peptide percentages. Here's what each declares.
NXTGEN Labs matches us on price, size and origin, and leads with Niacinamide. But a single copper peptide at an undisclosed dose, with no Matrixyl, is a smaller, less transparent peptide story than a declared 9% system.
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 12, ties 2, cedes 1. NXTGEN Labs genuinely matches us only on being Australian-made and 30ml, and takes just one category — a richer skin-feel from squalane. On the peptide system that defines the serum, we win outright.
Every ingredient. Both labels, side by side.
NXTGEN Labs publishes a full INCI — genuine transparency — but no peptide percentage. Note where the copper peptide sits: ninth, just after the preservative.
What NXTGEN Labs gets right.
A few things, and we'll state them plainly: it's the same $89.99 for the same 30ml, it's made in Australia like ours, and it puts Niacinamide high on the list. Squalane also gives it a slightly richer skin-feel than our lighter serum. Those are real, and we're not going to pretend otherwise.
But that's about the end of it. NXTGEN's copper peptide is the only one it has, it sits ninth on the label — after the preservative — and no percentage is disclosed, so you can't tell how much you're getting. There's no Matrixyl, and no antioxidant to protect a copper peptide that oxidises. We publish 1.2% GHK-Cu inside a declared 9% three-peptide system with Matrixyl 3000, protect it with Tocopherol, and add dual-weight hydration and madecassoside. Same price, same size, same country — and a materially fuller, fully-declared formula.
