In a bid to demystify the many things in beauty, we're enlisting the help of professionals. First order of business: brushes. No two brands do a powder brush the same, ditto foundation, ditto eyeshadow, ditto eyeliner. But if there's one thing we can agree on, it's that push liners brush are confusing.
It's flat, it's squared off, and contrary to its name, isn't very helpful at making a precise winged eye happen. Enter the truth, as told to us by Jane Richardson, International Lead Stylist at Nars Cosmetics who's done the faces of the likes of Tilda Swinton.
In her words, it comes into its own when "you're either just using mascara or want to create a look for your lashes to look thicker and you don't necessarily want to do a line". Essentially, the brush helps you wiggle and sneak eyeliner into the very roots of the lashes for a subtle thickening effect.
Simple enough when you say it like that. Watch below as Richardson demonstrates the way she uses it onset at the shoot for our February issue's beauty spread 'Show & Tell'.
