Abstract: A multifunctional microdermabrasion wand provides to the wand operator the capability to perform microdermabrasion of a skin surface while simultaneously delivering one or more skin treatment serums. The operator can also simultaneously deliver ultrasonic energy through the wand to the skin surface. The operational controls for the multifunctional wand provide for operator control of the quantity delivered of one or more serums. The system also provides operator control of the ultrasonic energy delivered by the wand and a feed back control system to maintain a preset energy delivery level. The wand allows for conducting microdermabrasion, serum infusion and ultrasonic energy delivery to the skin surface in any combination simultaneously as well as serially.
