Multi-Peptide + HA Serum
Reviewed by SerumTruth Editorial · Updated July 2026
A broad peptide serum for around fifteen dollars, with hydration built in. The catch is disclosure: none of the peptide levels are stated, so you take the doses on trust. As a low-cost, low-risk entry into peptides, it is still good value.
- Evidence18 / 30
Strength of the research behind the key actives
- Matrixyl 3000: moderate evidence
- Matrixyl Synthe'6: limited evidence
- Hyaluronic Acid: moderate evidence
- Score is the average of the key actives’ evidence grades.
- Potency21 / 25
Dosed at studied levels, not fairy-dusted
- Matrixyl 3000: dosed at a studied level
- Matrixyl Synthe'6: dosed at a studied level
- Hyaluronic Acid: dosed at a studied level
- Potency tracks how strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability14 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: clear dropper
- No fragile actives here, so packaging barely moves the score.
- Formulation4 / 10
Disclosure, active breadth, and ingredient generation
- 0 of 3 actives disclose a concentration
- 3 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Matrixyl 3000, Matrixyl Synthe'6
- Value14 / 15
What a month of use costs vs. the category
- About $12 per month to use
- $19.9 for 30 ml, used about twice a day (about 0.3 ml each time), so a bottle lasts about 1.7 months
- Band: $6/month or less earns full marks, $60/month or more hits the floor.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Matrixyl 3000 | n/a | Studied |
| Matrixyl Synthe'6 | n/a | Studied |
| Hyaluronic Acid | n/a | Studied |
The serum formerly sold as "Buffet": a broad stack of trademarked peptides (Matrixyl 3000, Matrixyl Synthe’6 and others) over multiple weights of hyaluronic acid, in a clear glass dropper. The peptides are the pitch, though The Ordinary does not disclose any of their levels, which is the transparency gap here. The peptides are not especially air-sensitive, so the clear dropper is a minor issue.
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.
