1. A method for tightening tissue with an ultrasound treatment, the method comprising:
coupling at least one piezoelectric therapy transducer to a skin surface,
wherein the at least one piezoelectric therapy transducer is housed in an ultrasound probe connected via a cable with a connector to a control system,
wherein the control system is configured to operate the at least one piezoelectric therapy transducer at one or more energy levels,
cooling the skin surface with a cooling system acoustically coupled to the skin surface,
wherein the control system is configured to operate the cooling system to control the cooling the skin surface,
wherein the at least one piezoelectric therapy transducer is configured to treat a region of interest comprising any one of the group consisting of: a dermal tissue, a fascia tissue and a muscle tissue;
wherein the at least one piezoelectric therapy transducer comprises an array of piezoelectric therapy elements configured to direct ultrasound energy into the region of interest with a planar or defocused ultrasound beam to a depth of up to 5 mm from the skin surface;
wherein a collagen fiber is located in at least a portion of the fascia tissue in the region of interest; and
transmitting the ultrasound energy from the at least one piezoelectric therapy transducer into the collagen fiber at a frequency in a range of 4 MHz to 15 MHz, thereby
heating the collagen fiber in the region of interest in the at least a portion of the fascia tissue to a temperature in a range of 60° C. to 90° C. to cause shrinkage of the collagen fiber for tightening of the skin surface.
