1. Not wearing one
We know it seems like an extra step in your makeup routine, but primer helps your makeup last for long hours. You won't need to worry about your eye shadow and eyeliner getting smudged when you dab eye primer prior to applying eye makeup. Face primers, on the other hand, will prevent your foundation from melting, thus keeping shine at bay and blurring your pores to oblivion.
2. Not using the right type for your skin
They're not all created equal. Just like skincare products, there are primers tailor-made for your skin type. If you're worried about shiny T-zone and large pores, nab ones with silicone to keep your oily-skin problem under control. Also, radiance-boosting primers will help normal to dry skin appear healthy and supple.

3. Only applying it before makeup
Need a retouch? Before you reach for your favorite compact powder, try tapping a pea-sized amount of primer on top of your made-up face instead. This technique prevents caking and instantly kills a slick complexion.
4. Using a brush for application
It's a great idea to use a makeup brush to apply primer on hard-to-reach areas, but using clean fingers will improve blood circulation, making you look healthier and glowing. Plus, the warmth of your hands will help your skin absorb the product faster.
