Setting spray is a liquid mist that can be used to increase the lifespan of your makeup. It is typically made with water and alcohol as its main ingredients. Setting spray is applied over your makeup to set everything in place, including your foundation base, concealer, eyeshadow, and whatever else you have on. The spray helps prevent your makeup from sliding, smudging, creasing, or fading quickly. It can help your makeup stay put all day long.
When the setting spray is sprayed onto your skin, the solvent evaporates, leaving behind the polymer. The polymer droplets merge together to form a film that helps lock makeup in place. Setting sprays typically blend your powders and cream together to look more natural. They usually have some type of botanical oils that help hydrate the skin and reduce makeup transfer and smudging.
In summary, setting spray is a must-have in your beauty arsenal if you want your makeup to last all day long. It helps lock makeup in place, prevents it from sliding, smudging, creasing, or fading quickly, and blends powders and cream together to look more natural.
