Abstract

Systems and methods for treating skin and subcutaneous tissue with energy such as ultrasound energy are disclosed. In various embodiments, ultrasound energy is applied at a region of interest to affect tissue by cutting, ablating, micro-ablating, coagulating, or otherwise affecting the subcutaneous tissue to conduct numerous procedures that are traditionally done invasively in a non-invasive manner. Lifting sagging tissue on a face, neck, and/or body are described. Treatment with heat is provided in several embodiments.

Claims

1. A method of treating sagging skin, comprising:

providing a probe that emits ultrasound energy;

coupling the probe to a skin surface over a region comprising subcutaneous fat, muscle, and connective tissue; and

delivering therapeutic ultrasound energy to the region at a treatment frequency of between 4 MHz and 15 MHz,

wherein the therapeutic ultrasound energy thermally treats at least one of the group consisting of subcutaneous fat, muscle, and connective tissue at a specific depth under the skin surface to reduce skin sagging.
