July to August is prime-time sweat-proof makeup wearing season, but with so many options (mascaras, foundations, shadows and pretty much every other product under the sun), it's a tough job to narrow in on what to apply and when. Luckily, E! Style Collective resident beauty pro Ashley Rebecca weighed in on what watertight formulas work for every summer sweat scenario.
First, it's important to note that stay-put makeup isn't a permanent solution, but it is a good tool for prolonging carefully applied makeup on hot and humid days. We're specifically looking for products with polymers, "a molecule that gives products wearability, but also evaporates after application so that makeup stays put without being heavy," said Ashley.
