ABSTRACT
Along with the textural and surface changes of the skin with age, come wrinkles. A natural loss of collagen and hyaluronic acid occurs, as well as a decrease in elastin resilience. The dermis thins, collagen decreases, and the skin folds upon itself, resulting in wrinkles. There are many different wrinkle scales used in medicine to categorize the severity of wrinkles. One example is the Glogau classification ( 1 ) wherein type I describes no wrinkles, type II describes wrinkles in motion, type III describes wrinkles at rest, and type IV describes only wrinkles ( Fig. 12.1 ).
