Doctor, i had this problem of p versicolor on chest and back for many years. Recently it has spread on my forearms and a little on the face as well. I've taken treatment. Applying keraglo AD lotion daily, using saborbar soap and ta king fluzon 150 mg tablets once a week. Its been two weeks and no major improvement is noticed by me. Shall i continue the treatment or ask the doctor to prescribe some other medicine?
