If it is down to lip balms causing this condition they would be banned or come with health warnings. Lip balms abound and purchased by billions of people- but ec is RARE. The same would apply to those with having their lips stretched after dental treatment surely if it was down JUST to this there be way more people with EC on the streets. I don't think it's so simple...
Could it be a combination of three ingredients if you like
1. the inappropriate over zealous use of lip balms by people 2) together with an impaired immune system so prone to 3) sensitivity to anything chemical in contact with the lips ie contact dermititis?
It does make logical sense to STOP messing with the lips and breaking a chain of almost addictive vicious compulsive loop and cycle that is not only painfull but anxiety inducing too and hence impacting on the Heath of the immune system.
to my mind this is a threeway approach cessation of lip messing adressing the immune system and really tackling a personal response to anxiety stress.
It's hard not to be fixated on your lips when they get into a state, it's also understandable how it "Messes with the mind "and strongly impacts on social life interaction etc which is rarther depressing and rubbish to self esteem and confidence etc etc Its impact is far reaching and devestatong to the point people feel isolated lost and are suicidal. Any of these "negatives" will have and are shown to have a baring on the immune system. ( the thymus gland which determines the health of the immune system is an area to seriously look at as is the thymus chakra....Daniel is an embodiement of the healing or activation of this chakra beautifully in his video!!!! You may need to read several sources about the thymus chakra for a fuller comprehensive picture. Both the thymus gland and thymus chakra are associated with the immune health)
