When creating the Westman Atelier Squeaky Clean Liquid Lip Balm (£35), which launches exclusively at Cult Beauty this month, makeup artist Gucci Westman wanted a hydrating treatment product that would still leave behind a beautiful hint of colour. Available in six shades (including Nou Nou, a cool pink tone), the formula is a "gel-ified oil", explained Westman, which means it doesn't feel goopy or sticky. In addition to moisturising dry lips, "it's made to give you that pick-me-up when you're feeling a little blah", Westman said.
