The Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
An expensive serum that asks you to buy a proprietary complex on faith while its disclosed actives are present at supporting levels. The ingredients that are named are fine and well-tolerated, but nothing here justifies the price on evidence. You are paying for the brand story and the texture.
- No active concentrations are disclosed
- Costly to use, about $243 a month
- Evidence14 / 30
Strength of the research behind the key actives
- Oligopeptide-177 (TFC8): preliminary evidence
- Hyaluronic Acid: moderate evidence
The average of the key actives’ evidence grades.
- Potency20 / 25
Dosed at studied levels, not fairy-dusted
- Oligopeptide-177 (TFC8): present, but below a studied dose
- Hyaluronic Acid: 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.

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: Oligopeptide-177 (TFC8)
Disclosure, active breadth, and current-generation or synergistic actives.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Oligopeptide-177 (TFC8) | n/a | Light |
| Hyaluronic Acid | n/a | Studied |
A lightweight serum whose pitch is the proprietary "TFC8" complex, built around the peptide Oligopeptide-177, with hyaluronic acid as the familiar supporting active, in a refillable airless pump. The signature complex is undisclosed and unstudied outside the brand. It feels elegant and absorbs cleanly.
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
A multicenter study linked a topical hyaluronic acid serum with better looking hydration, tone, and texture over several follow up visits.

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