Urban Decay All Nighter Long-Lasting Makeup Setting Spray, $32
At least three of us swear by this setting spray, so just trust us here! If you needed another testament to its longlasting magic — I brought a bottle of this setting spray when I was getting my makeup done for a friend's wedding just in case the makeup artist didn't have it — naturally, she did — and my look stayed flawless throughout the night. However, my bridesmaid dress, hair, and ankles (don't ask me how) didn't. — Jada Wong, Insider Picks editor
Without this spray, my eye makeup smudges like no other. It's a must-use to finish my makeup before I emerge into the unforgiving heat and sunlight. I also have the mini size for when I travel. If I forget it, I often just end up not wearing makeup during my weekend trips because it all ends up smudging or disappearing anyways. — Connie Chen, Insider Picks reporter
Applying makeup is fun until you look in the mirror a few hours later to see all of your hard work dripping down your face and wonder, what's the point of it all? Okay, I won't get too meta on you here, but I will tell you — whether you sweat a lot or not — you need this spray. It keeps your makeup in place like no other, making it a serious necessity for those sweaty summer days. — Remi Rosmarin, reporter
