Q. A 25-year-old male graphic designer presents with a six-month history of itchy, red patches on the elbows and knees. The patient reports that the itchiness worsens at night and the skin feels dry. He has tried using moisturizing lotions, which provide temporary relief. There is no history of asthma or allergic rhinitis, but the patient recalls having similar but milder symptoms during childhood. On physical examination, there are bilateral, well-demarcated, shiny, thickened patches of skin on the elbows and knees with overlying erythema and fine scaling. There are no vesicles or signs of secondary infection. Rest of examination is normal. What is the most appropriate initial treatment for this patient?
