I use Avon lip Conditioner with spf 15. I apply it religiously when I'm in the sun b/c if I don't I wake up with a big old cold sore the next day. I also use it all winter under lipstick and I never have chapped lips anymore-my lips used to get so bad that they would bleed. I just stocked up with 4 more tubes of this stuff-I can't say enough about it. It's great. I hope your lips get better soon.
