If you're obsessed with the bestselling E.L.F Putty Primer (which has been described as a less-expensive dupe for Tatcha's Silk Canvas Primer), you're almost certainly going to love the new E.L.F Putty Eye Primer (£5). This inexpensive little guy comes in six shades and promises to not only extend your eyeshadow wear for up to 12 hours but also intensify the colour of your eyeshadow — making brights brighter and shimmers more shimmery.
