Hi, I recently went from a hot country to a very cold country and my lips are pretty sore. It must have caught me by surprise and i wasn't prepared with a suitable enough lip balm. They have a bit of an inner rim - like a red wine stain, tho' it's not!! - which is painful, a feeling of tiny cuts and a little wee cut/ spot inside. I'm practicing through as don't want to stop- any advice ?
