Ruby & Millie £11
This lip gloss started the obsession with twist-up applicators. Ruby & Millie worked with Mitsubishi to create the mechanism, and many imitators have copied the design since the original launched. And it seems as though celebs can't get enough gloss either - Angelina Jolie wouldn't walk down the red carpet at the BAFTA's without it. Availabla from Boots.
