If i treat my lip condition like it is due to "stomach acidity" i get quite good results. Eat more alkalising foods and avoid wheat, dairy and oranges. Lemons are great alkalisers. Include Essential Fatty Acids like Udo's Oil - and continue taking it for a long time. I also agree with drinking loads of water - 2 to 4 litres a day. Treat it from the inside because thats where the problem is originating. Good luck :-)
