Setting sprays aren’t unnecessary products—these goodies are formulated with polymers (long molecules) that act as a shield over your makeup, protecting it from glam-risk factors such as sweat, heat, and life, in general. They are also packed with hydrators like aloe and hyaluronic acid that nurture your skin even when they sit on top of your foundation. To keep your makeup on fleek, we sourced and tested the absolute best setting sprays on the market.
