I'd planned to be The Corpse Bride for Halloween this year, but then I saw Make Up For Ever's Fluo Night Black Light Pigment, and I'm thinking of reworking my look just so I can use one.
As you can probably guess, it's a powder pigment that shines fluorescent under UV light! And this doesn't just mean glow-in-the-dark eyeshadow - it can also be mixed into primers, moisturisers, foundations, mascaras, lipglosses and powders, so you can use to them to create a really dramatic but easy Halloween beauty look.
They cost £12.50 each and are available here.
