Glow Up: Britain's Next Make-Up Star (often shortened to Glow Up) is a British reality television competition on BBC Three devised to find new makeup artists. Originally hosted by Stacey Dooley, the first series premiered on 6 March 2019. The contestants take part in weekly challenges to progress through the competition, which are judged by industry professionals Dominic Skinner and Val Garland, as well as weekly guest stars.

After the conclusion of the first series, Glow Up was renewed for a second series, which premiered in May 2020. The third series began airing in April 2021, with Maya Jama replacing Dooley as the presenter, with the fourth series beginning airing on 11 May 2022. The reality series was renewed for a fifth series beginning on 2 May 2023, with Leomie Anderson replacing Jama as the presenter. Although not confirmed, it is likely there will also be a sixth series as its submission period has already begun on the "Glow Up Casting" official Instagram page.
