He mentioned that he went on a healthy Diet before his lips started healing. Google eczema and salmon. Omega 3 is known to have strong anti-inflammatory effects.

Just chiming in with some personal info, I got my EC while I was at my 'healthiest' (gym, switched to a SUPER CLEAN diet, more water) and what's funny is I go the gym 6x a week, WALKING TO AND FROM UNDER THE SUN. That takes about 1.5 hours in total a day and that's just from walking! I also play football (soccer) so there is no way I'm lacking any sort of vitamin D, if anything, I'm under the sun quite a lot to be honest. Pretty ironic how I got my EC while switching to a cleaner diet, I cut out a lot of Sugar and instead of deep frying, I grill or bake them so essentially I was eating the same proteins but with definitely healthier sources of carbs and fat.

If it helps, I'm from the Philippines (searched tags on google about ec and Philippines btw, it definitely feels like I'm the first Filipino with it sigh) so it is definitely humid and always hot in here but I just recently moved to the States a week ago.

Forgot to add, well if it wasn't diet-related then my EC was most probably trauma-induced since I remember complaining to my dentist how my lips were more chapped and dry after I got my retainers and I definitely remember picking and peeling them prior to some visits a few months before I started noticing my lips turning white.

it doesn't attack the skin man just lick them they will heal. if you don't lick them they will never heal. havnt you ever seen normal people lick there lips? think about it, wouldn't it screw up there lips? it doesn't. its the only thing that has healed my lips. I used to never lick my lips too but then I got tired of it and licked them and they healed.
