Makeup Forever Face and Body Foundation
Sweat-proof, streak-free foundation is a godsend, so once you find the right one, hang on (or buy in bulk, whatever). Makeup Forever's full beauty line is a great entry point for long-lasting makeup—hence the name—but their satin coverage foundation is especially well-equipped for hot summer days .
