Thirteen copper peptide serums, ranked. Tap any card for the full ingredient-level breakdown.
Helloskin vs Allies of Skin
A $327 ectoin-and-antioxidant serum with the copper peptides declared as "complexes" near the bottom of the label.
Helloskin vs NIOD CAIS3
1% GHK-Cu + 1% GHK at premium pricing. Brilliant peptide chemistry — but no antioxidant, no Niacinamide.
Helloskin vs Double Bay Cosmetics
A 100ml serum with a bold 5% GHK-Cu, a BHA and 30 ingredients — big numbers, but no niacinamide, and copper efficacy is about delivery, not a bigger dose.
Helloskin vs NXTGEN Labs
Same $89.99, same 30ml, also Australian, with Niacinamide — but a single copper peptide at an undisclosed dose, no Matrixyl, no antioxidant.
Helloskin vs Suma Nurica
A mix-it-yourself powder + solution at $139 — the copper peptide is undisclosed, and the mixed serum runs clear.
Helloskin vs Cu Hair Skin
A little more copper (1.5%) and a lower price — but no Matrixyl, no antioxidant, no Niacinamide, and its 'expression' peptides are trace at the label's end.
Helloskin vs PeptiClinic
GHK-Cu paired with KPV, a genuine repair peptide — but no full INCI, and no percentage stated for either peptide.
Helloskin vs Ethan Thomas
A tidy 2% GHK-Cu single-peptide serum — but a stock, off-the-shelf formula (its INCI is resold under other brands), one peptide, no Niacinamide.
Helloskin vs The Ordinary
Eight peptides at trace concentrations under one "1%" claim. Sophisticated formula, opaque label.
Helloskin vs RegenMed Direct
A peptide-and-EGF serum with a long ingredient list — but just 0.5% GHK-Cu, undisclosed doses, no antioxidant, and no stated size.
Helloskin vs Wonderlini
A competent serum, but an off-the-shelf one — 1.5% copper on a stock white-label base (the same INCI is resold under other brands), no Matrixyl, no Niacinamide.
Helloskin vs Division Twenty
2% GHK-Cu in water with a preservative pair — no delivery system, no antioxidant, no supporting actives.
Helloskin vs Premium Peps
A 'triple peptide' serum that publishes no INCI, no percentages and no size — and carries a 'research use only' disclaimer.
No marketing, just chemistry.
The same honest method behind every comparison above.
Both full labels
We publish both complete ingredient lists and read them position by position — not the marketing headline.
Every % on the record
Our 1.2% GHK-Cu and 9% triple-peptide system are declared to the decimal — nothing hidden behind "complexes" or "1% lumped".
We concede real wins
Every comparison credits where the other brand genuinely beats us — ectoin, antioxidants, a higher single dose. Then we show the whole picture.
