Abstract: A skin treatment device includes a handle and a tip, having a skin applying surface, detachably coupled to the handle. A fluid delivery structure is formed at skin applying surface and has an aperture and a vacuum entry port. A fluid detouring path is defined between the aperture and the vacuum entry port for prolonging a traveling path of fluid from the aperture and the vacuum entry port. An abrading structure, an electrode structure, and a micro-needling structure are selectively provided at the skin applying surface with the fluid delivery structure to provide multiple functions of the tip.

Abstract: An apparatus for transdermal fluid delivery includes a handle and a tip, having a skin applying surface, being driven to move by a driving unit. A fluid delivery structure has an aperture formed at the skin applying surface and a vacuum entry port. An abrading structure, an electrode structure, and a micro-needling structure are selectively provided at the skin applying surface with the fluid delivery structure to provide multiple functions of the tip. A flow of fluid is delivered onto the skin applying surface through the fluid delivery structure to interact with the abrading elements and the electrodes before the fluid is returned and collected, so that three different skin treatments of abrasive peeling, electrical stimulation, and liquid infusion are achieved in one single structure for improving a skin structure.

Abstract: A device and methods for increasing the permeability of the skin's surface to fluid and/or drug delivery is described. The device comprises an abrasive media to remove the outer layer of the stratum corneum, while at the same time applying an electric current that stimulates the skin under the stratum corneum, and delivers fluids from a supply reservoir. The device may also have a vacuum function which evacuates fluid and skin debris from the surface of the skin and delivers the evacuated fluid and skin debris to a waste (or collection) container.
