Have you tried any hydrocortisone or corticosteroids? Both of these are used when treating Psoriasis and they bring down inflammation. I would highly recommend adding this to your aquaphor treatment because others on here have had success doing so. There are numerous causes for EC so if you can pinpoint what you think caused it then it will make your treatment and hopefully cure, that much easier. If your lips are trauma induced then I would treat it as if it were Psoriasis, which is what I'm currently doing. I'm using a vitamin d3 ointment called Calcipotriene, along with a steroid ointment called Desonide .005% and in between when my lips get a little dry I use Bepanthen wound healing ointment.
