How many days or weeks should it take to seen an effect with Elidel on thin skin with dermatitis? I used for nearly two weeks (12 days exactly) without any improvement for my so called "dermatitis" diagnosis by a dermatologist. Now I am concerned that I shouldn't have used it for that long without seeing results! Was this too long for me to use Elidel if dermatitis is not really what I have; and if so, what could have this done in terms of damage to normal skin?
