## Abstract

A system and method for ultrasound treatment of skin laxity are provided. Systems and methods can include ultrasound imaging of the region of interest for localization of the treatment area, delivering ultrasound energy at a depth and pattern to achieve the desired therapeutic effects, and/or monitoring the treatment area to assess the results and/or provide feedback. In an embodiment, a treatment system and method can be configured for producing arrays of sub-millimeter and larger zones of thermal ablation to treat the epidermal, superficial dermal, mid-dermal or deep dermal components of tissue.

## Claims

### Claim 1

An ultrasound treatment system configured for treatment of the photoaged effects in tissue, said ultrasound treatment system comprising:
a control system for facilitating control of the ultrasound treatment system;
a display system for displaying an image of at least one of epidermal, superficial dermal, mid-dermal and deep dermal tissues within a region of interest, said display system coupled to said control system; and
a probe system configured for targeted delivery of ultrasound energy producing arrays of sub-millimeter and larger zones of thermal ablation to treat said at least one of said epidermal, superficial dermal, mid-dermal and deep dermal tissue to cause reduction of the photoaged effects in tissue.
