What is claimed is: 1. A method of treating a patient's skin with a skin-treatment substance, comprising: providing a gauze pad on either a removable attachment device or on a head of a probe, the attachment device having a plurality of holes for respectively accommodating a plurality of electrodes
What is claimed is: 1. A method of treating a patient's skin with a skin-treatment substance, comprising: providing a gauze pad on either a removable attachment device or on a head of a probe, the attachment device having a plurality of holes for respectively accommodating a plurality of electrodes disposed on the head of the probe; removably attaching the removable attachment device to the head of the probe; and treating the patient's skin by providing the skin-treatment substance to the head of the probe and moving the head of the probe with the removable attachment device attached thereto, across portions of the patient's skin, wherein the head of the probe includes a channel region encircling at least one of the electrodes, the method further comprising: providing the skin-treatment substance to the channel region. 2. The method according to claim 1, wherein the attachment device is a polypropylene cap. 3. The method according to claim 1, wherein the head of the probe includes a plurality of return electrodes and an active electrode, and wherein the at least one gauze pad comprises: a first gauze pad disposed between the active electrode and the attachment device; and a second gauze pad disposed between the plurality of return electrodes and the attachment device. 4. The method according to claim 3, wherein the active electrode is centrally positioned on the head of the probe, and wherein the plurality of return electrodes are positioned on a periphery of the head of the probe surrounding the active electrode. 5. The method according to claim 3, further comprising: providing a conductive insulator between the first gauze pad and the second gauze pad. 6. The method according to claim 5, wherein the conductive insulator is made from a rubber material. 7. The method according to claim 1, wherein the providing step comprises: connecting, by way of a tube, the channel region to a syringe containing the skin-treatment substance. 8. A treatment method for reducing cellulite disposed beneath a skin region of a patient, comprising: a) applying a vacuum to the skin region to cause the skin region to be sucked towards a hand-held probe; b) heating the skin region by way of a heat lamp disposed on the hand-held probe; c) applying a vibration to the skin region, the vibration being provided by way of a vibrating plate that is placed on the skin region, the vibrating plate being disposed on the hand-held probe; and d) applying a sequence of bursts of electrical pulses to an array of electrodes that are placed on the skin region, the array of electrodes being disposed on the vibrating plate, wherein the sequence of bursts of electrical pulses and the vibration and the heating are provided to the skin region at a same time in order to reduce the cellulite disposed beneath the skin region of the patient. 9. The treatment method according to claim 8, wherein the array of electrodes correspond to parallel metallic stripes that are alternately connected to each other and that are provided on an outer surface of the vibrating plate. 10. The treatment method according to claim 8, wherein the array of electrodes include round electrodes alternately electrically connected to each other and that are provided on an outer surface of the vibrating plate. 11. The treatment method according to claim 8, wherein a D.C. current is applied between the electrodes and a ground plate connected to the patient. 12. The treatment method according to claim 8, further comprising the step of applying a cellulite-reducing substance to the skin region prior to providing the vibration and the sequence of bursts of electrical pulses to the skin region. 13. The treatment method according to claim 12, wherein a D.C. current is applied between the electrodes and a plate connected to the patient. 14. The treatment method according to claim 8, wherein the step b) heating is further accomplished by providing RF energy to the skin region of the patient. 15. The treatment method according to claim 14, wherein the RF energy is provided to the skin region of the patient by way of the RF energy being supplied to rollers disposed on a head of the probe. 16. An apparatus for reducing cellulite disposed beneath a skin region of a patient, comprising: a hand-held probe that includes: a vacuum unit configured to cause the skin region to be sucked towards a hand-held probe; a heating unit configured to heat the skin region; a vibration unit configured to apply a vibration to the skin region, the vibration unit including a vibrating plate that is configured to be placed directly on the skin region; an array of electrodes provided on a head portion of the hand-held probe; and an electrical pulse applying unit configured to apply a sequence of bursts of electrical pulses to the array of electrodes so that the bursts of electrical pulses are applied to the skin region when the array of electrodes contact the skin region, wherein the sequence of bursts of electrical pulses and the vibration and the heat are provided to the skin region at a same time in order to reduce the cellulite disposed beneath the skin region of the patient. 17. The apparatus according to claim 16, wherein the heating unit comprises a heat lamp disposed on the head portion of the hand-held probe. 18. The apparatus according to claim 16, wherein the array of electrodes correspond to parallel metallic stripes that are alternately connected to each other and that are provided on an outer surface of the vibrating plate. 19. The apparatus according to claim 16, wherein the array of electrodes include round electrodes alternately electrically connected to each other and that are provided on an outer surface of the vibrating plate. 20. The apparatus according to claim 16, further comprising a ground plate that is configured to be coupled to the patient, wherein a D.C. current is applied between the array of electrodes and the ground plate when the ground plate is coupled to the patient. 21. The apparatus according to claim 16, further comprising a substance applying unit configured to apply a cellulite-reducing substance to the skin region prior to providing the vibration and the sequence of bursts of electrical pulses to the skin region. 22. The apparatus according to claim 16, wherein the heating unit comprises an RF generator configured to provide RF energy to the skin region in order to heat the skin region. 23. The apparatus according to claim 16, further comprising: rollers provided on the head portion of probe to allow the probe to be rolled over the skin region of the patient, wherein the RF energy is provided to the skin region of the patient by way of the RF energy being supplied to the rollers.
