I am trying to figure out the raw part on top lip since it is different than bottom lip- it does not get thickened skin like bottom lip because it too raw for skin to hold there. I wish someone would have a biopsy of the raw area on top lip. I do not know if it is unrelated to the bottom lip since some people with EC just have it on bottom lip without raw area on top lip. I am not sure if the raw top lip is related to allergies. All I know is the raw skin was healed for 1-2 months in my case, then somehow went raw again. I have no idea if the raw area could lack fibroblasts in contrast to the bottom lip. Aloe vera is supposed to increase fibroblasts so it might help the raw part if it lacks fibroblasts.
