Sometimes when we put highlighter on our faces, we want a subtle glow. Just a cheeky sparkle to let everyone know that our inner unicorns are always there, even when it's a normal workday and we've got minimal makeup on.
But sometimes, we want our cheeks and cupid's bow to shine so freakin' brightly, you could see it in space. We want to blind our boyfriends and be a disco ball on the dancefloor - and that's okay too.
If the latter is your fave, you'll be glad to know that the good people of social media have blessed us with a makeup hack like no other. It's simple, it's affordable and it's sure to make you shine bright like a diamond.
17-year-old Australian blogger Arielle Stenner shared her simple hack with her followers, and the post soon went viral.
It involves using a touch of Bio-Oil as a primer for your highlighter - apparently, it turns your face into a "damn sunbeam".
Genius, right? Not only is it fab for your skin, it's fab for your selfies too. Cheers, Arielle!
