On your first dermatology visit, you will be mostly explaining your problem and symptoms to your doctor. Your dermatologist will need some information about your earlier medication, family history, and eating habits, and he would like to know if you have any known allergies. They will look into the affected area of your skin, mole, or acne. From there, they will examine the problem. Depending on the situation, they will recommend a plan of action and provide you a prescription and follow-up appointment.
