Retinal + Niacinamide Youth Serum
Reviewed by SerumTruth Editorial · Updated 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.
- Evidence24 / 30
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
Disclosure, active breadth, and current-generation or synergistic actives.
- Value12 / 15
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.
