Hello. I'm Dr. Christensen.
It isn't possible to diagnose your problem without an examination, but it sounds like you have a condition called seborrheic
dermatitis, or seborrhea. The cause of seborrhea is unknown, but many experts believe a fungus that normally inhabits human skin could play a role. Seborrhea can be treated with a variety of agents, including
corticosteroids, such as Efficort, coal tar preparations, antifungal creams (
terbinafine,
ketoconazole, etc.), zinc pyrithione and
selenium sulfide.
Efficort is fairly potent corticosteroid, so it should only be used on your face for a week at a time. Using it for longer periods could cause thinning and even worsening inflammation of your facial skin (a condition known as steroid-induced rosacea). Therefore, you should follow your dermatologist's instructions and only use Efficort for one week and then stop. If you then let your skin rest for two weeks, you can use the Efficort for another week, then stop for two weeks, and so on. If this routine doesn't adequately control the flaking in your eyebrows (and it might even allow your eyebrows to grow back), see your dermatologist for further treatment.
I hope that answers your question. Good luck!
