Yeah I am pretty sure I have EC...my bottom lips are 75% healed and my top lip is about 50% healed. Well I don't really do anything just leave my lips to heal no lip balms or anything just beeswax if it is cold or if I feel that my lips are dry.
and what exactly am I doing? using my humidifer for heat and humidity/ plenty of water/ recently started takin multi-vitamin pills for vitamin B. In addition avoid ANY contact with my lips including food and not stretch them too much.
