I Put 3 Makeup Primers to the Test During a 3-Day Music Festival

One/Size Secure the Sweat Primer ($15)

This was my first time using the One/Size Secure the Sweat primer, but I'm very familiar with the viral One/Size setting spray, so I had a feeling that this product was going to be a winner. This one is also water-based as well as aluminum-free. It promises to absorb sweat and even tighten pores. It's made with squalane, and for someone who suffers from dryness, that was a major win.
