Evidently, “wrinkles” are considered one of the major obstacles in this arena. In 2004, Botox Cosmetic™ injections were shown to be the most often performed cosmetic procedure in the United States.1 Cutaneous wrinkles, defined as furrows or ridges on the skin surface, appear to be multifactorial in etiology and a consequence of intrinsic and extrinsic aging (discussed in Chapter 6). While genetic predisposition is an important factor in developing wrinkles, engaging in particular life style behaviors such as excessive sun exposure and smoking are also known causes of cutaneous aging (see Chapter 6). This chapter will concentrate on wrinkles not caused by sun exposure but, rather, by intrinsic aging. Treatment approaches focus more on the condition itself, but also address behavioral elements pertaining to extrinsic aging.
