Posting on behalf of a friend. She has had a split lip; a deep central vertical split down the bottom lip, for over 9 months now (and through different seasons of course) and no doctor or specialist has yet found anything to help. At one point it was splitting further down from her lip a millimetre or so into the below skin. She has tried over the counter remedies, prescribed ones (not sure what as she is abroad) and also CBD oil. The latter briefly made a difference but then stopped working. Has had vitamin and mineral deficiency tests too.
She saw a dermatologist today (not the first one) who said that he hadn't seen anything like it in 45 years of practice. So I thought we would turn to mn to see if anyone has had any similar experience and found any solutions. Any help or advice would be great.
