Method and apparatus for therapeutic treatment of skin with ultrasound

Abstract

A method and apparatus of reducing human skin wrinkles, including applying a focused ultrasound beam to a region of human skin to stimulate or irritate a dermis layer in the region of the skin without adversely damaging an epidermis layer in the region of the skin so as to cause a change in the dermis layer of the skin that results in a change in a smoothness of the epidermis layer of the skin. In particular, relatively low power, low frequency focused ultrasound is applied to the dermis layer for a period of time sufficient to cause a biological response in the body wherein the biological response causes synthesis and/or production of new connective tissue that results in reduction or elimination of human skin wrinkles.
