As many of you who have ever stood before a camera know, the way you look in the mirror before you leave the house isn’t necessarily the way you’ll look in photographs. To help you stay abreast of this riddling dichotomy, here are a few tips to make yourself up for the cameras as well as for the real world.

According to makeup artist Napoleon Perdis, it’s always important to have a good starting ground. “Prepping with serum and primer is a non-negotiable,” he writes in the Huffington Post. “It’s the best start before makeup, gets that glow going (especially if you’ve been super stressed) and allows your foundation to go the distance.”

That being said, Perdis recommends putting just the right amount of foundation on (but not skipping it altogether). Don’t be scared it’ll show up in pictures – if you match it correctly to your skintone and only use as much as you need to lightly even out your complexion, you’ll be looking even more flawless in front of the camera.

As for real-life celebrity boo-boos, learn from the mistakes of Eva Longoria, Gwyneth Paltrow and others. Too much powder will make you look like you’ve just had flour blown all over your face, and undereye concealer should always be blended in.
