Seven 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 5% GHK-Cu, a BHA and 30 ingredients — big numbers, but past copper's plateau and no niacinamide.
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 Ethan Thomas
A tidy 2% GHK-Cu single-peptide serum with soothing botanicals — but one peptide, no Niacinamide, and the INCI hidden in a product photo.
Helloskin vs The Ordinary
Eight peptides at trace concentrations under one "1%" claim. Sophisticated formula, opaque label.
Helloskin vs Division Twenty
2% GHK-Cu in water with a preservative pair — no delivery system, no antioxidant, no supporting actives.
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.
