I have a bad case of seborrheic dermatitis
in my eyebrows. I tried Desonide, which helped, but when I switched to Elidel, it wasn't successful in controlling my seb derm. And my derm told me to switch back to desonide.
~10 days, twice daily desonide
~2-3 weeks twice daily Elidel
~10 days twice daily desonide+salycylic acid, 6%
~a few days Elidel
My treatment has probably gone on for a little over six weeks total (which is what's listed about).
