The idea of medical cosmetology is well recognized, and people commonly use medical cosmetology to keep themselves looking young and beautiful. But to rely on an operation or medication to maintain a youthful appearance or reshape the body is still not enough. If we can combine the concept of prevention, such as maintaining a healthy diet, with cosmetology, we come one step closer to the goal of total beauty as well as a more effective and holistic future status of the art. The idea of disease prevention in traditional Chinese medicine (TCM) is about encouraging people to pay attention to their daily life routine, especially to their diet and exercise. This research examines disease prevention throughout the history of TCM, which can be used to gain a fuller understanding of the potential role of disease prevention in medical cosmetology.
