Clinique iD is a revolutionary custom-blend moisturizer that combines a hydrating base with a targeted active concentrate. Available in 15 different combinations, Clinique iD lets you choose between 3 hydrating bases (a lotion, a gel, or a jelly) and 5 cartridges (which target fatigue, irritation, wrinkles, enlarged pores, and hyperpigmentation). Customized skincare has never been this simple!
