It's the semi-final, and just one professional and one creative brief stands in between the MUAs and the chance to make it through to next week's Glow Up final.Judges Val Garland and Dominic Skinner are joined by Guest Judge, the world renowned photographer and director Rankin, as the MUAs are booked on a beauty editorial for his magazine, Hunger.Stacey Dooley presents as Rankin challenges the MUAs to experiment with beauty, expressing themselves and creating a look for the beauty editorial's theme The Future. But there's a twist: the models will be photographed in a tank of water, meaning the final four MUAs must produce a make-up look that works well in the water.Rankin will also be looking at how well they work with him to create the perfect image, and if they're good enough their work will feature in his magazine.The following day at Glow Up HQ, the MUAs face their first ever surprise Creative Brief, where they are asked to produce a look based on one of the four classical elements: earth, water, air and fire. The looks are judged before Dominic and Val decide which two will enter the Face Off elimination. With a place in the final at stake, the MUAs are asked to pull off a rainbow eye with seamlessly blended colour.
