Give the primer a full minute to dry before layering anything on top
The best way to apply primers is with your fingers. "A makeup brush will just drag the primer around," says makeup artist Mary Phillips.
When you overload on primer, it pills under your foundation. A small drop is plenty. Gently rub into the skin for even coverage.
Give the primer a full minute to dry before layering anything on top. If you're applying liquid foundation or tinted moisturizer afterward, finish with a dusting of translucent powder.
Gently patted around the eyes and on the lids, primer acts as a three-in-one. It prevents makeup from smudging or creasing by absorbing oils, it softens crow's-feet, and it counteracts redness.
Skip any spot treatments if your primer already contains anti-acne ingredients.
Dab on a lip primer to prevent lipstick from feathering or settling into lines. If you don't have a lip primer on hand, one designed for your face can work as well.
To set your makeup, follow this magic order: primer, liquid foundation or tinted moisturizer, translucent powder.
