The Serum
Reviewed by SerumTruth Editorial · Updated 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.
- Evidence14 / 30
Strength of the research behind the key actives
- Oligopeptide-177 (TFC8): preliminary evidence
- Hyaluronic Acid: moderate evidence
- Score is 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
- Potency tracks 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.
- 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: Oligopeptide-177 (TFC8)
- Value3 / 15
What a month of use costs vs. the category
- About $243 per month to use
- $405 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 |
|---|---|---|
| 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.
