The Immortelle Overnight Reset Oil-in-Serum ($59; usa.loccitane.com) is a gorgeous nighttime treatment from L’Occitane. Its a fabulous, lightweight serum with a luxurious texture that helps plump, hydrate and brighten lackluster skin. Its a slightly thick oil that goes on like a serum and sinks in almost instantly. I usually use this on its own and don’t need anything extra this time of the year. There’s a slightly strong floral scent much like the other products in the Immotelle line and I could also use this as a primer underneath makeup because of the sheer texture. I love how my skin looks the next day when I use this at night and is definitely something I’d recommend if you want to include a lightweight oil-serum in one into your skincare routine.
