If you've ever wanted to channel your inner Mario Dedivanovic and give your makeup a Kim Kardashian-approved bake, now you can do it for just a fiver. The Revolution Loose Baking Banana Powder (£5) is perfect if you wear medium-to heavy-coverage foundation and want to accentuate your contour. It has a subtle yellow tint (hence the name), which is good because it neutralises and colour corrects any unwanted redness in the skin tone.
