Multi-Peptide + Copper Peptides 1% Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
The value benchmark of the category: multiple studied peptides at a disclosed copper level for roughly the price of a lunch. It is the obvious first serum to compare everything else against, even if you re-cap it fast.
- Fragile actives sit in a clear, exposed package that lets them degrade
- Evidence18 / 30
Strength of the research behind the key actives
- Copper Peptide (GHK-Cu): moderate evidence
- Matrixyl 3000: moderate evidence
- Argireline: limited evidence
The average of the key actives’ evidence grades.
- Potency20 / 25
Dosed at studied levels, not fairy-dusted
- Copper Peptide (GHK-Cu) (1%): dosed at a studied level
- Matrixyl 3000: dosed at a studied level
- Argireline: present, but below a studied dose
How strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability6 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: clear dropper
- Air- or light-sensitive actives (Copper Peptide (GHK-Cu)), so packaging is scored.
Delivery tech plus packaging, and packaging only counts when actives are fragile.
- Formulation6 / 10
Disclosure, active breadth, and ingredient generation
- 1 of 3 actives disclose a concentration
- 3 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Copper Peptide (GHK-Cu), Matrixyl 3000
Disclosure, active breadth, and current-generation or synergistic actives.
- Value12 / 15
What a month of use costs vs. the category
- About $19 per month to use
- $32 for 30 ml, used about twice a day (about 0.3 ml each time), so a bottle lasts about 1.7 months
What a month of use costs: full marks at $6 a month or less, the floor at $60 a month or more.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Copper Peptide (GHK-Cu) | 1% | Studied |
| Matrixyl 3000 | n/a | Studied |
| Argireline | n/a | Light |
A genuine multi-peptide formula (copper peptides, Matrixyl 3000, Matrixyl Synthe’6, Argireline, SYN-AKE) that discloses its 1% copper level, which is unusual transparency at this price. It is lightweight and layers well. The frosted-glass dropper is the weak point for a copper peptide that oxidises.
How it’s delivered
Air- and light-sensitive actives (vitamin C, copper peptides) lose potency fast in the wrong packaging, so delivery and the bottle are scored, not just what’s on the label.

What the research says
After CO2 laser resurfacing, people using a copper peptide regimen felt skin quality looked improved, though measured wrinkle scores did not differ.

In a 12-week trial, palmitoyl pentapeptide reduced the look of fine lines and wrinkles compared with a placebo cream in women with photoaged skin.

A study of the active, not this exact product. What matters for the score is whether this serum uses it at a comparable dose.
