This is a luxurious creamy Ampoule with a sophisticated citrus scent. It moisturizes well enough you don’t need to layer it with other serums, this gets the job done. Hydrating plus it delivers great ingredients like vitamin c, my skin is happy to use this one. My husband however, can not use this because his skin is sensitive to all citrus oils in skincare, so be careful if you are sensitive to other citrus oils like orange peel or grapefruit.
