Abstract
A method and system for heating a skin area surface of an individual from an initial temperature to a treatment temperature in a treatment time period exceeding 0.5 sec, where the treatment temperature is in the range of 40°-60° C. An RF generator provides a continuous wave RF voltage energy or a quasi-continuous wave RF voltage across first and second electrode, where at least the first electrode is associated with an applicator that is displaced over the skin surface. The system further includes a skin temperature measuring device or an applicator displacement speed measuring device; and a CPU that monitors a skin temperature or an applicator displacement speed. The CPU turns off the RF energy when the skin temperature is above a predetermined temperature or the displacement speed of the applicator is below a predetermined speed, in order to prevent overheating of the skin.
