Yellow is the unsung hero of colour correcting, a multi-tasker you'll love having in your vanity. Use it to cover bruises, veins, dark circles, and even redness. Yellow colour correctors work best for fair skin as they effectively cancel out any purple or blues to give you a natural finish. Secret hack: If you don’t want to use a corrector, you can also swap it for a medium coverage concealer with a yellow undertone.
