dont worry dude we all gone through this stage..find a stuff helps you to hide ec .one option works for me is honey..put it on and leave lips alone.it may help you to have at least 70% normal lips
or
do moist healing treatment
search for longterms post and find tests suit for you/you doubt...then see a good derm and request him to do that tests.tell him you need to clear all your doubts before applying harmful stuffs over lips.
