There’s nothing sexy about dry, chapped lips after they’ve been dried out by winds and central heating. No matter how tempting, don’t lick them! Exfoliate with an old toothbrush, choose a moisturising, natural lip balm like Burt Bees Sun Protecting SPF 8 Lip Balm and avoid those with ingredients like camphor and menthol, which can worsen a cracked, inflamed mouth.
