'My top tip is to apply it using a damp Beautyblender,' she says. 'This allows you to really press the powder into your skin so it doesn't budge as the day goes on.'

If you're on the go, it's fine to use a pressed powder to stop your foundation from slipping off, as long as it's super-light. 'To prevent shine throughout the day, pick up something really finely milled like Charlotte Tilbury's Airbrush Flawless Finish,' adds Floyd. 'You can keep topping it up and it never, ever gets cake-y, which is why it's a go-to powder in my kit - for my clients and myself.'
