You won’t find any #sponsored content here, just honest, relatable and independent advice.This week, Mamamia's senior lifestyle writer Charlotte Begg tries the latest celebrity contour technique.

Celebrity makeup artist Mary Phillips has taken the traditional order you apply your makeup in and flipped it on its head.

In a recent TikTok video of hers, which has since gone viral, the LA-based makeup artist – who works with Kendall Jenner and Hailey Bieber – shared her backwards technique to achieving a seamlessly blended base.

And you bet I had to try it.

Here's everything you need to know about the latest celebrity contour technique, and my honest review on it.

But first, remember that trend when people used... lube as primer? Watch our beauty editor try it out.

Who is Mary Phillips?

For some quick context, Mary Phillips is an American celebrity makeup artist who has worked with the Kardashians for years.

Like Kim has Makeup by Mario, and Kylie has Makeup by Ariel, Mary works mostly with Kendall. She also regularly does makeup for Hailey Bieber, Jennifer Lopez and other Kardashian family members.

And whatever makeup she does – whether it's simple or bold – the base always looks flawless.

What is her contour technique?

A little while back, the internet learned about Phillips' method to getting your contour to look as natural as possible. Creators started trying it out for themselves and #MaryPhillips started trending on socials.

Fast forward to now, and the makeup artist has joined TikTok to create her own videos, show how she does it and which products she uses.

"To me, it makes more sense," Phillips says of the technique.

"It's like laying down the bones under the skin – the contour and the highlight being the bones and the skin being the foundation."

Instead of applying your cream bronzer, blush and concealer after foundation, Phillips applies her cream products first.

Yep, you read that correctly: contour and conceal,thenapply foundation.

After applying those products to the usual places, the makeup artist insists you use a big fluffy brush (think the one you'd use for your powders) to apply your foundation, as it liberally spreads the product, making it look like you're barely wearing it at all.

In a second video showing the same technique, Phillips goes into more depth, showing the exact products she uses to get the look. (Don't you love when they don't gatekeep?!)

She starts off by contouring her cheekbones, forehead, under her chin, and her nose. After blending it all in, she applies the smallest amount of concealer to the high points of her face, adds cream blush, and goes in with foundation.

Once that's all done, she finishes her face off like usual – with powders, eye makeup and lip products.
