i man for me my first epesoide of ec lasted for about 1 months just the top lip and the triangular part keeped peeling and becoming white when in contact with water. all i did was bite it spit it out and apply blistex and did that for about 3 weeks and it just healed and went back to normal.
so i wonder all the time well if it healed once im sure my body can heal it again. although the first time it wasnt as chronic but maybe that becasue i keeped it moist maybe if i just left it it would of crusted like doing the leave it alone theory. thats why i reckon your derm is right when saying she treated the person from just months of continual vaseline.
anyways thats my 2 cents for the day. im off to work next week so im pretty excited!
