8 Contouring Tips to Learn From the Kardashians' Makeup Artist

"If you're having a fat day," quipped Rob, "take your contour shade and paint it under your chin." Start directly under the end of your chin, then blend down and back into your neck to create the illusion of a sharp jawline.

Anyone who has applied makeup in the back of a dark cab late at night knows that lighting is crucial during glam time. But bright lighting isn't necessarily the best atmosphere, either. "Aim for the lighting that you'll be in," suggested Rob. So if you'll be attending your friend's beachfront wedding, do your makeup in natural light.

If you don't like your nose, you can pretend you have a slimmer schnoz with careful contouring. Using the Tweezerman Brush iQ Pointed Concealer Brush ($12), shade underneath the tip of your nose and along the sides, bringing the contour up, under the brow bone, and into the eye socket. This creates natural-looking definition that makes your eyes pop and your nose blend in.

"You don't want your hair to look like a lace-front wig," explained Rob. Use a sponge to buff the contour color you applied around your forehead as far into your hairline as possible so your makeup and hair look seamless.

Rob prefers to work with cream products to create a sculpted face, but it's not what works best for everyone. "If you have oily skin, set your foundation with powder, then use powder products to highlight and contour." Everyone else? You should be using creams.

"It's all about creating contrast," Rob said. Fair skin doesn't need a lot of highlighter, as it's already light in color — you should be contouring this complexion to create dimension. "On dark skin, you need to focus on using highlighter. With contour, you don't have anywhere to go," he explained. Meaning, you want to add brightness to darker skin tones, which will really make the complexion pop.

Rob insisted that this is one of the keys to making your contour (and makeup as a whole!) look as natural as possible. Before you apply any cosmetics at all, take Tweezerman's Foundation Sponge, dampen it with a bit of water to soften it, then use the sponge to buff moisturizer into your skin. Later, after you've applied your contour and highlight, blend the shades with the same sponge. "Using a damp sponge will give you a softer look," explained Rob. The moistened sponge also makes it easier to blend your makeup.

"When creating a cheekbone," said Rob, "the color should graduate. You need to blend so lines aren't sharp." First, find the hollows of your cheekbone using the handle of a makeup brush or the side of your hand. Using the Tweezerman Brush iQ Pointed Foundation Brush ($22), start creating your contour line from your ear to under the apples of your cheeks. (The color should be darkest closest to your hairline.) End your line by creating a lightly sketched "little Nike swoosh" under the apple of your cheek.

That said, when asked how he decides where to stop contouring under the cheekbone, Rob said it depends on your mood. "If you want, you can continue the line down the side of the chin," he said, which will create a very chiseled, vampy look.
