US Patent 7014639 Apparatus for aesthetic skin treatments

An apparatus for aesthetic manipulation of the skin having a large pulsator with plurality of light emitting diodes of at least two different wavelengths and a small pulsator with one light emitting diode is disclosed. A frequency modulator automatically modulates the emitting frequency of the tight emitting diodes to a plurality of different frequencies. A power output modulator is provided to modulate the power output of the light emitting diodes. A phase switching subsystem allows selection between a plurality of operating phases, each operating phase operating the frequency modulator and power output modulator in a different predetermined manner. Calibration subsystem connected in circuit with the light emitting diodes calibrates the power output of the light emitting diodes. A vibrator is provided to vibrate the large pulsator. A vibration switching subsystem selectively activates the vibrator.
