Kim Kardashian shares her beauty secret: make-up artist Mary Phillips new technique

Last night Kim Kardashian shared her beauty secret, by posting a picture of herself on Twitter.

In the shot, Kim Kardashian, 31, is seen with some kind of yellow-based primer smeared all over her otherwise make-up free face.

The reality star posted the picture with the caption: “Glamming up with @1maryphillips!!! A little confused by her new technique BUT I know it will be fab!”

Celebrity make-up artist Mary Phillips counts Kim Kardashian, Jessica Simpson, Jennifer Lopez and Salma Hayek among her famous clients.

Kim Kardashian later tweeted a shot of the finished look, writing: “Flash a little bright but here’s the after pic!!!”

While it is not clear exactly what kind of product was used on Kim Kardashian's face, it appeared to be some kind of color-correcting primer

She was having her make-up done ahead of attending the Jeep Brand and USA Basketball celebration of the launch of the 2012 Jeep Wrangler Unlimited Altitude at LA Center Studio.

While it is not clear exactly what kind of product was used on Kim Kardashian’s face, it appeared to be some kind of color-correcting primer.

Yellow-colored primer is usually used to disguise under-eye circles and mild red tones on the face.

Despite the fact that Kim Kardashian has long been an advocate of experimenting with make-up, she has also posed make-up free in the past – describing the experience as “empowering”.

The reality star said: “Make-up is fun, but it’s just another accessory.

“Posing make-up free is really empowering. Why not show people what I really look like?

“I’m happy with myself, and this is who I am.

“As much as it’s fun to glam up, the most important thing is to be comfortable in your own skin – with or without makeup.”
