Thank you for your information, Dr. Seife. I have the so-called combination skin. I have used Dove soap bars for almost 6 years and Nivea cream as a moisturizer and sunscreen for UV protection. However, I started seeing melasma on my nose last year around this time. It it is getting worse day by day. I visited a dermatologist and got several prescriptions to try out e.g. Anti-pigment lotions, face washes, and Serums but nothing changed. What do you recommend to me?
