Helloskin vs The Ordinary
They list eight peptides at undisclosed concentrations under one "1%" claim. We declare every gram of every peptide — 9% total active peptides across three pathways. The full ingredient-level breakdown — no marketing, just chemistry.

Why 9% declared beats 1% lumped.
The Ordinary's "Multi-Peptide + Copper Peptides 1%" label combines eight peptides under a single "1%" total. The math means each individual peptide is at a trace concentration — and we don't know which is which.
per peptide, if split evenly
The Ordinary lists 8 peptides totalling 1%. INCI position suggests GHK-Cu (Copper Tripeptide-1) is the largest of the eight, but even at the most generous estimate, individual peptide concentrations sit in the 0.1–0.4% range. Below the threshold where most peptides demonstrate clinical effect.
declared, peptide by peptide
Helloskin lists three peptides at clinical concentrations: 1.2% GHK-Cu, 5% Palmitoyl Tripeptide-1, 3% Palmitoyl Tetrapeptide-7. Every concentration on the label, every peptide working in its therapeutic range.
↓ Helloskin · 3 peptides at clinical %
Three peptides delivered at 9% combined — full working concentrations reaching the dermis.
↓ The Ordinary · 8 at trace %
DMI delivery works — but eight peptides at ~0.125% each means trace amounts reach the dermis.
The peptide load, peptide by peptide.
Both formulas have penetration enhancers. The difference is what's in the bottle to deliver.
The Ordinary's formula contains 9× less total declared peptide. Their multi-peptide approach is real — but at lumped trace concentrations, each individual peptide sits below the dose levels shown to produce clinical effects in published studies.
The 1% you buy isn't the 1% you apply.
GHK-Cu is redox-active. Without antioxidant protection, the copper peptide degrades fast — and The Ordinary's formula has none.
degradation within 72 hours of ambient air exposure
GHK-Cu is redox-active — the copper ion readily accepts or donates electrons. In oxygen, moisture, and light, it degrades fast.
Helloskin includes Tocopherol (Vitamin E) as a dedicated antioxidant. The Ordinary's INCI list contains no antioxidants for peptide stabilisation.
All 15 categories. Where each wins.
Helloskin wins 14 of 15 on the formula. The Ordinary wins 1: value per dollar.

Sixteen functional ingredients vs forty-nine including humectants, amino acids, sugars, and preservatives.
What The Ordinary gets right.
The Ordinary deserves real credit. They democratised peptide skincare. Before DECIEM made $32 multi-peptide serums standard, copper peptide formulations sat behind $150+ luxury price tags or in injectable clinics. They opened the category to millions of people who would never have tried peptides otherwise.
The formula itself is more sophisticated than most ingredient-conscious shoppers realise. It includes a real penetration enhancer (Dimethyl Isosorbide), genuine multi-weight hyaluronic acid, an amino acid + sugar humectant complex, and Allantoin for soothing. The peptide variety — eight different peptides — is genuinely broad.
The critique isn't of their formula philosophy. It's of the label. "1% Copper Peptides" tells you the combined concentration of all copper peptides, but with eight peptides in the formula, individual concentrations land in the trace range. You don't know whether the GHK-Cu is at 0.5% or 0.05%. And without antioxidant protection, whatever concentration is on the label degrades fast once the bottle is opened.
For someone trying peptides for the first time at a budget price point, The Ordinary is a reasonable entry. For someone who wants to know exactly what they're applying — and to know it's stable, supported, and at clinical concentrations — that's a different product.
What people actually ask.
Isn't The Ordinary's "1% copper peptides" the same as your 1.2% GHK-Cu?
Doesn't The Ordinary have more peptides than Helloskin?
The Ordinary has DMI for penetration — isn't that the same as your delivery system?
Is The Ordinary a bad product?
Why does The Ordinary use Phenoxyethanol and Chlorphenesin?
Is the price difference worth it?
