The lip balm that I used to use changed formula and now makes my lips itchy and flakey. I've tried all the ones in the shops and they either have ingredients that I know I react to or I've tried them and they don't work. On the whole I get away with not using one at all but there's been a nasty cold wind for a few days now so my lips are sore and dry. Would something like olive oil or coconut oil do the trick, or are they too runny?
