A+ High-Dose Retinoid Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
A genuinely high-dose retinoid serum with unusually clear disclosure, pairing a top-of-range 1% encapsulated retinol with a gentler ester and proper protective packaging. You pay a prestige price, and the strength is not a beginner level, but on potency, delivery and transparency it is one of the stronger cosmetic retinoids for the appearance of fine lines.
- Built on strong-evidence actives
- Encapsulated Retinol dosed at a clinical, high-end level
- Every active discloses its concentration

Strength of the research behind the key actives
- Encapsulated Retinol: strong evidence
The average of the key actives’ evidence grades.
- Potency25 / 25
Dosed at studied levels, not fairy-dusted
- Encapsulated Retinol (1%): dosed at a clinical, high-end level for its category
How strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability20 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: encapsulated (protects and time-releases the active)
- Packaging: airless, opaque
- Air- or light-sensitive actives (Encapsulated Retinol), so packaging is scored.
Delivery tech plus packaging, and packaging only counts when actives are fragile.
- Formulation8 / 10
Disclosure, active breadth, and ingredient generation
- 1 of 1 actives disclose a concentration

What a month of use costs vs. the category
- About $26 per month to use
- $85 for 30 ml, used about once a day (about 0.3 ml each time), so a bottle lasts about 3.3 months
- Frequency is set by Encapsulated Retinol, which is used no more than 7x a week, so a bottle stretches further
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 |
|---|---|---|
| Encapsulated Retinol | 1% | Clinical |
A disclosed 6.5% stabilised retinoid solution, layering a 5% retinoid ester blend (hydroxypinacolone retinoate) with 1% liposomal-encapsulated retinol and a blue-green algae extract, in an opaque airless pump. The 1% encapsulated retinol sits at the top of the over-the-counter range, and the encapsulation and opaque pump suit a molecule that oxidises fast in air and light. This is the assertive end of a cosmetic retinoid, so ease in.
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
Silicone-particle encapsulation extended retinol stability and was linked to less visible irritation than standard encapsulation in human testing.

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