Retinol Youth Renewal Serum
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
Retinoids are the most-proven anti-aging actives there are, and this is the delivery done right: encapsulated, time-released, in packaging that actually protects it. You pay a prestige price and you take the percentage on trust. On evidence and stability, it earns its keep.
- Encapsulated delivery protects and time-releases the active
- Air- or light-sensitive actives in protective, opaque packaging
- No active concentrations are disclosed
- Evidence26 / 30
Strength of the research behind the key actives
- Encapsulated Retinol: strong evidence
- Hyaluronic Acid: moderate evidence
The average of the key actives’ evidence grades.
- Potency21 / 25
Dosed at studied levels, not fairy-dusted
- Encapsulated Retinol: dosed at a studied level
- Hyaluronic Acid: dosed at a studied level
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.
- 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: Encapsulated Retinol

What a month of use costs vs. the category
- About $28 per month to use
- $92 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 | n/a | Studied |
| Hyaluronic Acid | n/a | Studied |
A three-form retinol serum (a fast-acting retinol, a time-released encapsulated retinol and a supporting booster) buffered with hyaluronic acid for cushioning. The encapsulation is the point: it meters the retinol out to limit the flaking and stinging that scare people off, and it lives in an opaque airless pump that protects a molecule that hates air and light. Murad does not disclose the retinol percentage, which is the one real knock on transparency.
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 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.
