The MD Codes are an innovative method for facial modelling and wrinkle reduction that are defined in a total of 75 possible injection points. This ground-breaking technique was developed by the renowned Brazilian plastic surgeon Dr Mauricio de Maio, an expert in non-invasive aesthetic procedures. A member of the Brazilian Society of Plastic Surgery, Dr de Maio has produced a comprehensive guide to the use of Allergan’s Juvederm® Vycross® fillers for face contouring. During his worldwide lecture tours in recent years, he has presented this procedure and explained its benefits.
