Liquid Peptides
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
A polished, comfortable peptide serum from a serious brand, but the evidence and the pricing do not line up. The headline peptides carry limited support, the doses are undisclosed, and you pay a lot for the count on the label. Pleasant to use, hard to justify over cheaper multi-peptide options.
- Key actives carry only limited or preliminary evidence
- No active concentrations are disclosed
- Evidence14 / 30
Strength of the research behind the key actives
- Argireline: limited evidence
- Matrixyl Synthe'6: limited evidence
The average of the key actives’ evidence grades.
- Potency20 / 25
Dosed at studied levels, not fairy-dusted
- Argireline: present, but below a studied dose
- Matrixyl Synthe'6: dosed at a studied level
How strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability16 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: airless, opaque
- No fragile actives here, so packaging barely moves the score.
Delivery tech plus packaging, and packaging only counts when actives are fragile.
- Formulation3 / 10
Disclosure, active breadth, and ingredient generation
- 0 of 2 actives disclose a concentration
- 2 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Matrixyl Synthe'6
Disclosure, active breadth, and current-generation or synergistic actives.
- Value7 / 15
What a month of use costs vs. the category
- About $41 per month to use
- $68 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 |
|---|---|---|
| Argireline | n/a | Light |
| Matrixyl Synthe'6 | n/a | Studied |
A concentrated blend of ten peptides, Acetyl Hexapeptide-8 and Matrixyl-family messengers among them, in an opaque tube. It is fragrance-free and pleasant to layer, but none of the individual peptide levels are disclosed, and several are the trendier expression-line peptides whose evidence is limited. The tube is fine for peptides, which are not especially fragile.
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.
The actives, explained
What the research says
In Chinese subjects, twice-daily argireline cream lessened the look of wrinkles around the eyes more than a placebo cream after four weeks of use.

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