Dermatology and cosmetic models can go a long way in communicating difficult to visualize techniques and anatomy.
Aging Skin Model
This model showcases the aging process. It was designed to give patients a greater understanding of how and why their hair turns grey and thins. By showing both normal anatomy and aging anatomy (on different sides of the model) a patient can easily understand how their skin and hair age, and what goes on beneath the surface. Sometimes showing just the affected state of the anatomy is not enough- the patient also needs to understand how normal anatomy would look, and e able to compare the two.
