Hello!
A common cause of this pattern is seborrheic dermatitis. This condition is treated with one of several topical treatments or an oral medication sometimes used. The exact diagnosis needs to be establised by direct exam and you should see a dermatologist to check this out and prescribe the necessary treatment.Follow up questions are welcome if that would be helpful.
Good Luck, Anthony Bray MD
