oh boo, this is just the formal name for protopic, which didn't work for many of us.
here's another excerpt:
Management of exfoliative cheilitis is difficult but it has
responded to treatment with reassurance, topical steroids,6
psychotherapy and tranquillizers.7 Some cases can resolve
spontaneously. Our patient’s condition was resistant to
emollients and life-style changes; only the very potent topical
steroid Dermovate helped, but relapse soon followed when it
was stopped. Topical tacrolimus has successfully cleared the
condition.
