A typical skin body exam requires a comprehensive review of every part of your skin. Your examiner will ask about any moles that concern you, and will review these, along with all others. The examiner will generally use a dermatoscope to magnify and light the skin; and may measure or take pictures of the moles themselves. You will be required to take off clothing and wear a medical exam gown during the exam. The exam itself typically takes 20 minutes.
