A method and system for aesthetic skin treatment. The system includes a treatment energy source for generating a treatment beam and a treatment beam deflecting mechanism configured to direct the treatment beam to a treated skin area. One or more video cameras configured to capture a treated skin area and communicate captured treated skin area image to a processor. Based on a captured treated skin area the processor constructs a three-dimensional representation of the captured skin area and controls a treatment energy beam deflecting mechanism to deflect the treatment energy beam to follow the three-dimensional representation of the captured skin area.
