Setting spray is a cosmetic product designed to help makeup last longer throughout the day. It is typically applied after completing your makeup routine and works by creating a protective layer over the makeup. This helps to prevent smudging, fading, or settling into fine lines, ensuring a fresh appearance for hours. Most setting sprays come in a liquid form and are dispensed through a spray nozzle. They can vary in formulation, with some offering additional benefits like hydration or oil control. Popular brands include Urban Decay, MAC, and NYX, each providing different options to suit various skin types and preferences.
