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.

Provided is a foot exfoliator with a high-gloss nail polisher in which one surface of a hard plate such as a glass plate is divided into a foot exfoliating region and a nail polishing region, the foot exfoliator including a foot exfoliating part, in which one protrusion selected from protrusions having a circular shape, an elliptical shape, and a rhombic shape and a protrusion column are periodically and repeatedly arranged in a predetermined region of the plate, and a nail polishing part, in which a plurality of vertical stripe protrusions or inclined stripe protrusions are arranged to perform nail polishing in regions of an area of the plate excluding the foot exfoliating part.

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.

A cleaning head for a personal care appliance includes an elastic bladder having a bladder wall enclosing a fluid. The bladder wall has an inner base portion with a base thickness, which may be non-uniform, and a plurality of spaced projections extending outwardly from the inner base portion. The bladder is fixedly attached to a receiver portion of a bladder support, and a retainer is provided for attaching the bladder support to the personal care appliance such that the bladder support is drivably engaged by the personal care appliance. At least some of the plurality of spaced projections are configured to dynamically engage and disengage with neighboring ones of the plurality of spaced projections during use.

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.
