Make-up artist Rose Gallagher shares her tips and tricks for using concealer – and answers the questions people are always asking her about it. In this tutorial she walks us through her advice on how much to use, where to apply it, setting with powder and making sure it lasts for the day. Rose said: "One of the things I am most frequently asked about is concealer. It seems we’re all in the same quandary; we want to use it because it helps to brighten the eye area and cover any dark circles. "But when it’s on, we find that it either feels too heavy or sits in fine lines. With concealer, I think a few mindful steps when applying and setting can make all of the difference."
