What your doctor has told you seems quite correct. You may be suffering from seborrheic melanosis on your face. I wonder what you mean by greedy. If you cannot afford the treatment your doctor has offered please visit another doctor. The fact you feel your doctor is greedy means you do not trust your doctor. Trust is as imoortant as medicines when treating a patient. Find a doctor whom you can trust before going forward with any treatment suggested by them. This is a cosmetic problem which is treated by different doctors using different methods. Warm regards. Dr. Rajdeep Mysore. Chirag Hospital Bangalore
