If you scroll through Arielle Stenner’s Instagram (@ariellxe), you’ll find bright wigs, bold colour, flawless eye makeup and some seriously shimmery highlighter.

How does she do it? Compared to other makeup hacks, this concept is startlingly simple: primer. It makes sense. We prime our face before foundation, our eyelids before eyeshadow and our lips before lipstick, so why not prime the high points of our face before highlighting? Well, technically there aren’t primers for that. BUT, Arielle has found that Bio-Oil works like a primer for her highlighter. And judging from her selfies, this trick is going down a treat!

If you don't have Bio-Oil in the cupboard at home, you can still give this highlighter hack a whirl with similar oils. beautyheaven loves Sukin BioNatural Skin Oil, Swisse Macadamia and Chamomile Face Oil and RosehipPLUS® Rosehip Oil.

“Apply Bio-Oil on the place where you are going to highlight and it turns your highlight into a damn sunbeam,” Arielle posted on Instagram. “Apply a tiny layer of it where you put your highlight then brush your highlight over the spot and BAM that’s how I do it,” she wrote.

In the comments of her Instagram pic, some followers speculated about whether the oil would disturb foundation. But Arielle jumped in with a promising reply. “I haven’t had any problems with it! But it could [differ] depending on the type of foundation your wear, I guess.”

For a glow like Arielle’s, we're willing to give it a go!
