Thanks for writing to us.
From the description it seems you could be having seborrheic dermatitis
or Pityriasis alba
. Use a mild steroid
cream like hydrocortisone cream
along with tacrolimus 0.01% cream. Hopefully in two to three weeks time, you should see desirable response. i would have been in better position to answer this query, if you could send me an image of your lesions. For the same, you may tag me using ask a specialist feature of this website.
Hope this helped.
