In winter when the weather's cold, a good lip balm should be an essential in your make-up bag, handbag, bedside table...anywhere within arm's reach, really. And one that's a long-time favourite with celebrities and beauty experts is Laneige Sleeping Lip Mask. Made from deeply nourishing ingredients such as shea butter and coconut oil, plus antioxidant vitamin C, it cushions the lips in a layer of hydration while gently sloughing off dry skin, leaving them feeling soft and smooth.
