A system and method that scans areas of a human body to identify unattractive characteristics and make cosmetic enhancements is modified for medical monitoring and optionally for treatment. A 3-D model of the exterior surface of the human body is created, and the scanned data is analyzed by characteristics of reflectance and surface topology to identify unhealthy characteristics. Because people will use a cosmetics system widely and frequently, base lines of patients' conditions can be created through frequent monitoring over a long time period, so that potentially dangerous changes from the base line can identified quickly and reported on. When appropriate, precise applications of medications to treat affected areas may be made automatically. Controlled and precisely directed dosages of medications may be applied to reduce the risk of undesirable side effects. Medicines may also be applied over a large area of skin and during a long period of time to achieve desired treatments.
