I don't know what cured them, but my lips were horrible, cracking, peeling, hurting all the time. Then for 3 days I was eating salty in-shell sunflower seeds and I noticed that my lips were healing and I thought that was crazy because all of that salt should have made them worse..Then it hit me..(I'm slow)..lol It was the sunflower seed oil. So I went and bought some and keep it on my lips and they are doing great now..I also pour a little on my salad too because I didn't know if just rubbing it on would do it or if I have to have it in my system..so I do both. It has worked great for me. If you can give it a try..hopefully it will work for you too. I I also tried olive oil for awhile..it did not work...seems it has to be sunflower oil.
