MAC Lipstick in Ruby Woo (£17.50) was a winner across the board: "It's an iconic shade that's stood the test of time," said Michael Ashton. Graham and makeup artist Neil Young are also fans, as was Rihanna (pre-Fenty Beauty, of course), who created her own version with MAC a few years ago called Riri Wu (it sold out in minutes). Makeup artist Allan Avendaño (who works with Camila Cabello, Sarah Hyland, and Lucy Hale) said its Ruby Woo's brightness and blue undertones that make it so universal, while it's semi-matte formula makes it less in your face than some of the newer long-wearing liquid formulas on the market.
