When I worked in dermatology, one of the doctors recommended a lip balm with hydrocortisone. I can't remember the name of it, but i have found that Dr Dan's makes one. It is sold on the dermstore online and on
Amazon. It is very effective in healing cracked, dry lips. It is also said to be hypoallergenic. I have also found that any lip balm with shea butter works well for me. Aquaphor may work well, but some Aquaphor products contain an antibiotic, and I had a reaction to the cream.
