Retinol Youth Renewal Serum
Reviewed by SerumTruth Editorial · Updated 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.
- Evidence26 / 30
Strength of the research behind the key actives
- Encapsulated Retinol: strong evidence
- Hyaluronic Acid: moderate evidence
- Score is 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
- Potency tracks 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.
- 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
- Value10 / 15
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
- Band: $6/month or less earns full marks, $60/month or more hits the floor.

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.
