Claim:
A method for treating stretch marks in skin, said method comprising: identifying a skin surface disfigured by a stretch mark; identifying a region of interest under said skin surface, said region of interest comprising at least a portion of a dermis and a fibrous fascia; coupling an ultrasound probe to said skin surface; wherein said ultrasound probe comprises an ultrasound therapy element and a motion mechanism inside the ultrasound probe; wherein the motion mechanism is controlled by a control system in communication with the ultrasound probe, delivering ultrasound energy, using said ultrasound therapy element, to said region of interest to form at least one thermal lesion at a temperature of greater than 60 degrees Celsius in said region of interest; and activating said motion mechanism via said control system for mechanical movement inside the ultrasound probe for controllably creating a plurality of thermal lesions along a line within said region of interest to initiate a response that leads to improving an appearance of said stretch mark.
