When you spend your valuable time perfecting a glass skin makeup look or faking the perfect faux flush, you likely want to make sure your hard work doesn’t go to waste. But determining whether to use setting powder vs. setting spray isn’t always that clear. While both products have their merits—and both will help keep makeup in place—there are certain situations in which you may want to use one over the other. Ahead, we’ll explain what setting powders and setting sprays do, outline the differences between both, and share makeup-setting tips you’ll come back to time and time again. Read on for the details, plus a look at some of our favorite setting powders and setting sprays to try. What Is Setting Powder? Setting powder is a type of powder makeup product designed to help set liquid makeup and prolong wear time. There are a couple of different types of setting powders, including loose powders and pressed powders. Loose powders, like the Lancôme Long Time No Shine Loose Setting Powder, are great for baking makeup and mattifying the skin. Pressed powders, such as the Urban Decay All Nighter Waterproof Setting Powder are useful for lightly setting liquid makeup and minimizing unwanted shine. They can also be tinted or untinted—the former adds an additional layer of coverage, while the latter helps set makeup without adding any pigment. What does setting powder do? The main purpose (and benefit) of setting powder is, quite simply, to set your makeup. Dusting a loose or pressed setting powder onto your skin after applying your liquid makeup products can help prevent them from smudging, creasing, or melting and create a smooth canvas for powder products, such as blush or bronzer. Setting powders can also help mattify the skin and minimize unwanted shine. As such, they tend to be a great pick for those with oily skin types. There are plenty of good setting powders for dry skin, too—the key to avoid emphasizing dryness is to use it sparingly, rather than coat your entire face.
