Citrus smells like a fresh, bright, and clean scent, mixing fruits like lemon, lime, and orange. It’s super energizing and zesty. Think of the sharp smell of a freshly peeled orange or the crispness of a lemon. Citrus smells like that zesty aroma when opening a new can of lemon-lime soda. It’s often used in fragrances to give them a light, lively pop.
