Q. My foundation often looks cakey by lunchtime. Is there a way to smooth it back out? Dusting on powder seems to make it worse.

A. Makeup artists employ this trick: Lightly spritz your face with a moisturizing spray, such as Jurlique Lavender Hydrating Mist ($21; jurlique.com), then use a makeup sponge—or your fingers—to smooth out any dry patches. If you don’t have a spritz handy, you can also pat your face with lightly moistened paper towels.
