Facial aesthetic medicine is advancing and evolving rapidly, with the spread of cutting-edge products and innovative ways to use them. One of these new ways or methods is MD Codes or Doctors Codes. MD Codes is a system developed by my mentor Dr. Maurício de Maio, a Brazilian plastic surgeon, considered an authority in aesthetic medicine. Composed of codes formed by letters and numbers, the method guides the doctor and provides accurate information about the location on the face, the anatomical layer, ideal instruments, method of application and volume and type of product to be used. The MD Codes indication goes beyond rejuvenation.
