Let's talk oily eyelids. Gross, right? But they're the reason why your eyeshadow winds up migrating into the crease of your lids, instead of staying put like it's supposed to. And honestly, there's almost nothing worse—especially when you've spent half an hour on a meticulous smoky eye.
One way to counteract this phenomenon is to prime your lids before you slick on the shadow. Right now, I'm testing out Guerlain's new Ombre Éclat Eye Primer ($33, available at Guerlain boutiques, Shoppers Drug Mart Beauty Boutiques and department stores). It's a creamy powder that helps shadow adhere, and it also treats the eye area thanks to smoothing polymers and hydrating dry oils. The verdict? It still doesn't make shadow budge-proof, but it's a heck of a lot better than going without primer at all.
In a pinch, you can also use a thin layer of liquid concealer or foundation to prep the lids, and then dust with powder. This will help soak up some of the oils on your lids and give the shadow something to grip on to.
Or, you can simply switch from your usual eyeshadow to a waterproof cream version. Since I usually can't be bothered with the extra steps of primer, concealer, foundation and/or powder, this is my favourite time-saving trick. Dior makes a waterproof shadow called Eye Show—I love Undressed Beige, a shimmery, goes-with-anything shade. You can also try Clinique Touch Base for Eyes or Revlon ColorStay 12-Hour Eyeshadow.
