I have had a rather large (dime) size age spot on my face for the last 5 yrs or so and now it has changed. It has gone from flush to raised and itchy sometimes. I have used fade creams and other remedies to not avail, and have tried aloe and tea tree oil as well. Do I need to see a specialist in Dermotology for this or is it ok to ignore. I have no health insurance and do not want to spend money needlessly. Any help in this matter will be greatly appreciated.
