Abstract
Devices and methods for contactless skin treatment use feedback power control for non-invasive treatment of skin and human tissue. Electromagnetic energy heats skin or tissue. A feedback system measures an output physical quantity before the output of electromagnetic waves from the device into the patient. Alternatively the feedback system scans values of a physical quantity on or near the patient. The devices and methods allow for delivering the optimum amount of energy to the patient while reducing the thermal load of the device. Methods and an apparatus for treatment of target biological structure by combination of magnet treatment and electromagnetic treatment. The method and apparatus may be used for aesthetic applications, e.g. cellulite treatment, body shaping, skin rejuvenation or enhancing skin appearance.
