Luna Sleeping Night Oil
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
A gentle, comforting retinoid oil for the appearance of a smoother, more rested-looking complexion, softened by the azulene-rich botanical oils. The ester is milder than a true retinol, the level is undisclosed, and the price is firmly prestige, so you pay for the feel and the finish as much as the active. A nice easing-in option for people who find retinol serums too harsh.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Retinyl Propionate | n/a | Studied |
A blue-tinted night oil built on a gentle esterified retinoid (hydroxypinacolone retinoate, a trans-retinoid ester), balanced with blue tansy and German chamomile oils rich in soothing blue azulene, in a tinted glass dropper. The ester form is milder and slower than retinol, and the concentration is not disclosed, so it reads as an easygoing retinoid oil rather than a high-dose treatment. It gives the striking blue colour to a light, fast-sinking oil for night use.
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
A regimen with retinyl propionate improved the look of periorbital wrinkles about as much as a prescription tretinoin regimen, with less visible irritation.
A randomized, controlled comparative study of the wrinkle reduction benefits of a cosmetic niacinamide/peptide/retinyl propionate product regimen vs. a prescription 0.02% tretinoin product regimen. British Journal of Dermatology, 2010. PubMed ↗
A study of the active, not this exact product. What matters for the score is whether this serum uses it at a comparable dose.
