Quite possibly the OG long-wear liquid formula, Anastasia Beverly Hills Liquid Lipstick (£20) is smudge-proof, water-resistant, transfer-proof, kiss-proof, and mask-proof. Basically, once you apply it, it will not budge until you remove it with a waterproof or oil-based makeup remover. And it's not just us who love this formula. It's a favourite among makeup artists, too, including London-based Tania Grier. Make sure you layer up on the hydration before and after using this lipstick, though. It's budge-proof abilities can make the lips a little drying over time, but it certainly delivers on staying power.
