According to some embodiments, a skin treatment assembly comprises a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container, a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use, and at least one rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface.

Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

An abrasive tip is used to exfoliate skin and tissue through abrasive materials integrated in the tip. The tip also delivers fluid to the skin and vacuums the fluid and abraded tissue during treatment. Treated skin will look younger and healthier in appearance. In an implementation, the tip is replaceable and disposable.

According to some embodiments, a method of treating a skin surface of a subject comprises heating a skin surface, abrading native skin tissue of a subject using a microdermabrasion device, wherein using the microdermabrasion device comprises moving the microdermabrasion device relative to the skin surface while simultaneously delivering at least one treatment fluid to the skin surface being treated and cooling the abraded skin surface.

An apparatus for treating skin has a console with a user input device and a handpiece assembly. The handpiece assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handpiece assembly. A manifold system is coupled to the console and controlled by the user input device. The manifold system is configured to hold releasably a plurality of fluid sources and deliver fluid from at least one of the plurality of fluid sources to the handpiece assembly.

The present invention is an applicator tip for a hand piece assembly used in dermal abrasion procedures, the applicator tip having a cap shape with a plurality of apertures that form ports communicating with a fluid supply line in the hand piece assembly and a vacuum source to remove the abrading fluid. The fluid is introduced onto the outer abrading surface of the applicator tip through a first central aperture and spreads out along the outer abrading surface when the applicator tip is placed against the patient's skin. Recesses in the outer abrading surface establish pathways for the abrading fluid to move along as the applicator tip is moved over the patient's skin. The fluid emitting from the central port is moved into one of four quadrants defined by recesses in the outer abrading surface, each quadrant serving as a fluid chamber that receives fluid from the central fluid supply port. Each sector shaped chamber includes within its border a C-shaped barrier with its opening facing a dividing sector wall. As the applicator tip forms a seal with the patient's skin, fluid is introduced through the supply port and through the entrance of the chamber, filling each chamber with working fluid as the working fluid flows to and around the C-shaped barrier. Disposed inside each C-shaped barrier is a respective vacuum port that removes the working fluid from each chamber. Fluid from each chamber is vacuumed through its vacuum port after having flowed around a maze-like path, navigating the C-shaped barrier and sector walls in a vortex flow pattern.

According to some embodiments, a method of treating a skin surface of a subject comprises heating a skin surface, abrading native skin tissue of a subject using a microdermabrasion device, wherein using the microdermabrasion device comprises moving the microdermabrasion device relative to the skin surface while simultaneously delivering at least one treatment fluid to the skin surface being treated and cooling the abraded skin surface.

A microdermabrasion system includes an applicator tool including a central handle portion with a treatment tip at a distal end of the handle, where the treatment tip includes an abrading surface formed on a front surface of the tip. A proximal end of the elongated handle is coupled to first and second arms, forming an opening in the hand piece through which a user can insert one or more fingers. The handle supports a bottom side of a user's finger while the user grips the handle. In an implementation, the handle includes an indentation for at least one finger. In an implementation, the treatment tip is removable and replaceable

According to some embodiments, a skin treatment assembly comprises a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container, a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use, and at least one rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface.

A skin treatment device includes: an elastic enclosure having a hollow center chamber with an opening at a proximal end thereof; a lip around a perimeter of the opening; protrusions and channels on the lip, which selectively: (i) permit expulsion of air and water from the chamber during initial compression of the device against the skin; (ii) terminate the flow of air and water from the chamber when the lip has been sufficiently compressed against the skin to form a seal between the lip and skin; and (iii) permit air to enter the chamber upon decompression of the device and breaking the seal; and at least one outlet valve on the enclosure configured to permit an additional flow of air and water out of the chamber during compression and to resist admission of air or water into the chamber during decompression. A skin treatment method is also disclosed.
