What does it mean for your purchase?

COSRX has no verified price in this record, so a fair unit-cost comparison remains unavailable. Do not substitute a 150 mL offer.[1][2]

What has not been demonstrated?

This label comparison does not establish which finished serum works better or is safer. Individual tolerance and additional benefit cannot be predicted from the selected names.

What do the label differences mean?Exact names, disclosures and cost limits

Different presentations

Match the exact size before comparing an offer. This COSRX record is the 50 mL mini.[1][2]

Different disclosures

The Ordinary names 1% copper peptides. COSRX’s six-peptide name counts components; it is not a comparable concentration.[1][2]

Documented differences

The recorded COSRX mini is 50 mL; The Ordinary record is 30 mL. Both selected lists include Copper Tripeptide-1 and Acetyl Hexapeptide-8.[1][2]

LABEL FACTS AND THEIR LIMITS

What the sources tell us.

What do the source labels mean?

Human studies describe what happened in their participants and tested preparation. Laboratory studies examine a model, not clinical results in shoppers. Case reports describe individual events, not how often they occur.

Safety assessments review specified uses and concentrations. Manufacturer labels identify recorded product facts. Neither is a guarantee of results or individual tolerance. Source type is not a quality score.

What these sources cannot establish

Source type: Human ingredient study · Safety assessment

Recorded labels do not establish a clinical winner or years of safety for these complete formulas.[3][4]

Read the evidence and what it means

Source type: Human ingredient study · Safety assessment

The Argireline trial concerns a preparation, not either retail product in this pair. CIR addresses specified cosmetic safety uses, not a comparative benefit trial.[3][4]

Different study preparation. Not a test of either compared serum.

Editorial interpretation

This is a comparison of selected label information, not a complete clinical efficacy or safety review. Missing product-level evidence here is not evidence that either product is harmful or ineffective.

Cost and the exact presentation

Editorial interpretation

COSRX has no verified price in this record, so a fair unit-cost comparison remains unavailable. Do not substitute a 150 mL offer.

Read the evidence and what it means

Editorial interpretation

Selected names, no verified COSRX availability or comparable cost, and no finished-product head-to-head clinical evaluation. Scientific review pending.

What is recorded on the labels?

Source type: Manufacturer label

The paired manufacturer sources document the recorded product names and selected ingredients. These lists are incomplete, formulas may change, and manufacturer information is not independent clinical corroboration.[1][2]

Manufacturer links establish ingredient presence only. Scientific references support the research statements above. Formulas can change; check your purchased packaging.

A LITTLE MORE CLARITY

Questions about these products

Do shared names mean equal results?

No. Ingredient research and label overlap do not establish equal performance of finished formulas.[3][4]

Is there a fair cost comparison?

Not yet. No COSRX price is published here because the availability information requires clarification.[1]

Randomized, placebo-controlled; 60 Chinese participants, 3:1 allocation, four weeks.
What was reported
The abstract reports improved eye-area wrinkle measures with Argireline relative to placebo.
What this supports here
An example of ingredient research with a defined population and duration, rather than a test of either compared copper serum.
What it cannot establish
Four weeks in one population. Neither CAIS3 nor The Ordinary’s copper serum is the tested product identified in the abstract. No product winner or long-term safety conclusion follows.

What it cannot establish
Does not test these finished products or establish their safety over years. NIOD’s exact label name is not silently equated with a different name in the report.
