Thou shalt take the time to prime.
Applying a primer is an extra step that's incredibly worthwhile when you have a long day—or night—ahead. Primers are packed with silicone, which prevents the oil on your skin from breaking down your makeup. Silicone also smooths over pores and fine lines so foundation doesn't settle into them and look uneven over time, says celebrity makeup artist Pati Dubroff, who worked with Naomi Watts and Charlize Theron at the 2013 Oscars®. Before you apply any other makeup, smooth a primer all over your face, including your eyelids. (You can find primers created specifically for the lids, but a face primer, used sparingly, will also do the trick.)
