Dr. Scott Sattler summarizes cosmetic Botox injections for Seattle patients
Why do aging faces have wrinkles ?
The muscles of facial expression initiate and preserve the major lines and wrinkles of our faces. The ‘crow’s feet’ , ‘11 lines’ and forehead creases are the lines of facial expression than are most associated with facial aging. The sun also contributes to the very fine lines and wrinkles of facial skin as well. There is an important distinction between lines of facial expression and sun-aged skin. Sun-aged skin has very fine lines and wrinkles that are not perpetuated by the muscles of facial expression, and are not corrected with Botox.
