Luna Sleeping Night Oil
Reviewed by SerumTruth Editorial · Updated 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 a month of use costs vs. the category
- About $27 per month to use
- $105 for 35 ml, used about once a day (about 0.3 ml each time), so a bottle lasts about 3.9 months
- Frequency is set by Retinyl Propionate, 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 |
|---|---|---|
| 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.
