Buy Now, Use This Weekend: 5 Sweatproof Primers to Keep Your Face Intact

Not to knock our body's natural air conditioning system, but there's a serious downside to the sweat-prone summer months: Namely that as the mercury skyrockets, our face becomes a slip-n-slide that renders the time we spent putting on our makeup a complete waste. That's why stocking up on mattifying, longwear products is an absolute must this time of year—and that all starts with a reliable primer.

With the proper base, your makeup won’t budge—even in sauna-like conditions or after the most grueling SoulCycle class. Beyond that, the best primers also function as IRL Instagram filters, blurring imperfections, smoothing pores, and even offering a subtle glow. With all this in mind, we’ve rounded up the five best sweatproof primers on Amazon to withstand whatever this weekend throws at you—and we do mean this weekend, since they're all available with Prime's one-day shipping.

Happy shopping!
