Same idea: a retinoid delivered overnight in a water-free oil that spreads thin and layers under a moisturizer.

The trade-off

Luna uses hydroxypinacolone retinoate, a gentler retinoid ester at an undisclosed strength, with blue tansy and chamomile oils, while The Ordinary uses plain retinol at a stated 1%, which is stronger and more likely to irritate, so start twice a week.

Sunday Riley Luna Retinol Sleeping Night Oil dupe

Luna Retinol Sleeping Night Oil costs about $55 for 15 ml ($108.44 / fl oz). The closest match below is The Ordinary Retinol 1% in Squalane at $11.90, about 89% less per ounce. Each pair is compared on format, finish and key ingredients, including what the dupe doesn't do.

Night face oil that delivers a retinoid ester in avocado, grape seed, blackberry seed and chia oils; blue tansy gives it its colour. A few drops after cleansing, at night only.
