Retinal + Niacinamide Youth Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
A disclosed, above-typical-range retinaldehyde dose with genuine encapsulation and a real ceramide barrier assist, not just a retinoid serum with a trendy adaptogen label. The niacinamide and ceramides earn their keep alongside a retinoid that already carries the strongest evidence in the category. Priced like the prestige retinal it is, but the formulation and packaging back it up.

Strength of the research behind the key actives
- Retinaldehyde: strong evidence
- Niacinamide: moderate evidence
- Ceramides: moderate evidence
The average of the key actives’ evidence grades.
- Potency24 / 25
Dosed at studied levels, not fairy-dusted
- Retinaldehyde (0.15%): dosed at a clinical, high-end level for its category
- Niacinamide (5%): dosed at a studied level
- Ceramides: 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: encapsulated (protects and time-releases the active)
- Packaging: tinted glass
- Air- or light-sensitive actives (Retinaldehyde), so packaging is scored.
Delivery tech plus packaging, and packaging only counts when actives are fragile.
- Formulation7 / 10
Disclosure, active breadth, and ingredient generation
- 2 of 3 actives disclose a concentration
- 3 key actives (breadth credit caps at 3)
- Current-generation or synergistic: Retinaldehyde, Ceramides

What a month of use costs vs. the category
- About $20 per month to use
- $68 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 Retinaldehyde, 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 |
|---|---|---|
| Retinaldehyde | 0.15% | Clinical |
| Niacinamide | 5% | Studied |
| Ceramides | n/a | Studied |
0.15% stabilized retinaldehyde held in a cyclodextrin inclusion complex, a molecular-cage encapsulation that protects the fast-oxidizing retinoid and slows its release, above the typically studied 0.05-0.1% range for this active. A disclosed 5% niacinamide sits high on the ingredient list, right after the carrier base, and three named ceramides (NP, AP, EOP) plus cholesterol and phytosphingosine round out a genuine barrier-support trio alongside hyaluronic acid and squalane. A run of adaptogenic mushroom and root extracts (reishi, maitake, shiitake, ashwagandha) supplies the "adaptogen" marketing language without being an independently studied cosmetic active in this library. It ships in a tinted glass pump on top of the cyclodextrin encapsulation, a belt-and-suspenders approach that suits a retinoid at this concentration.
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
Clinical studies using skin replica image analysis suggested topical retinaldehyde supported a better looking appearance of photoaged skin, well tolerated.
Clinical use of topical retinaldehyde on photoaged skin. Dermatology, 1999. PubMed ↗
Topical 5% niacinamide was linked to more even looking skin tone, softer looking lines, and less visible blotchiness after 12 weeks.

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