Abstract: A method for irradiating skin and deeper tissue using unpackaged LED lights to improve skin and tissue absorption of low level light energy may be provided. The apparatus embodied by the method may be formed by selectively mounting chip-on-board LEDs in various array so that the skin gets irradiated from all angles. The LEDs may be associated with a heat sink provided by the substrate of PCB to more effectively dissipate its heat, allowing the apparatus to run at higher outputs.

Abstract: A pumping system assembly is configured to adjust a flow rate of a liquid in a hydro dermabrasion system. The pumping system assembly includes a peristaltic pump. A tube is joined to a first opening on the peristaltic pump with a first line connector and joined to a second opening on the peristaltic pump with the second line connector. A hydro dermabrasion handpiece is configured to administer the liquid and connected to the first line connector with a first line. A liquid reservoir is configured to store the liquid for the hydro dermabrasion system and connected to the second line connector with a second line. Optionally a microcontroller is connected to the peristaltic pump and programmed with instructions to engage the rotor in a clockwise manner drawing liquid from the liquid reservoir and transferring the liquid to the hydro dermabrasion handpiece.
