Approaches for percutaneous blepharoplasty are provided. An electrosurgical device includes: a hand-piece; a tip connected to the hand-piece; and two needles extending from a distal end of the tip. The hand-piece is structured and arranged to connect to an electrical energy source, and to convey electrical energy from the electrical energy source to the needles in a percutaneous blepharoplasty procedure.

According to an aspect of this disclosure, there is provided an apparatus (42) configured for use with a personal care device (2). The apparatus (42) is configured to provide visual guidance to a user on movement of the personal care device (2) across a body of a subject, wherein the personal care device (2) is configured to perform a personal care operation on a plurality of successive treatment areas of the body by successively moving the personal care device into a plurality of successive treatment positions on the body each corresponding with a respective one of said successive treatment areas. The apparatus (42) comprises a projection unit (22) configured to project a light pattern on to a surface of the body, and a processing unit (46). The processing unit (46) is configured to control the projection unit (22) to project the light pattern on to the surface of the body in a projection position indicative of a next treatment position on the body to which the personal care device (2) is to be moved by the user from a current treatment position on the body.

Apparatuses, compositions and methods for removing cells which interfere with regenerative processes. The apparatuses, compositions and methods selectively kill partially functional and/or non-functional cells versus functional cells while protecting functional proliferative cells to the extent that, upon removal of the killed cells by disintegration or scavenging, functional cells replace the partially- or non-functional cells.

Methods and systems are disclosed for removing a tattoo from a subject's skin by application of a cold plasma that is delivered via a liquid-gas mixture. The plasma can be delivered in the form of gas bubbles, in which at least a portion of gas is in the form of a plasma.

A method for determining parameters for operating a light source within a photo-thermal targeted treatment system is disclosed. The method includes cooling a treatment location, administering first laser pulses at the treatment location, the first laser pulses having thermal energy below a known damage threshold, tracking skin surface temperatures at the treatment location while administering the first laser pulses, estimating a relationship between parameters for operating the light source and the skin surface temperature by fitting tracked skin surface temperature to a correlation model, determining a safe operating range for the light source to avoid thermal damage at the treatment location while still effectively targeting the chromophore, administering second laser pulses at the treatment location, the second laser pulses staying within the safe operating range for the light source, and adjusting the light source according to the tracked skin surface temperatures to stay within the safe operating range.

A temperature measurement system for measuring a temperature of a measured surface includes: 1) a first temperature sensor; and 2) a reference surface including a second temperature sensor integrated therein. The first temperature sensor includes a field of view simultaneously covering both at least a portion of the measured surface and at least a portion of the reference surface, thus is configured for simultaneously taking a first measurement of both the portion of the measured surface and the portion of the reference surface. The first measurement of the reference surface taken by the first temperature sensor is compared to a second measurement taken by the second temperature sensor for use in calibrating the first temperature sensor.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

The present invention provides a device for rejuvenating a region of skin or mucosal tissue, comprising: a pulsed electromagnetic frequency generator; a plurality of electrodes in communication with the pulsed electromagnetic frequency generator and an RF tissue diathermy device. The electrodes apply the pulsed electromagnetic power and the RF tissue diathermy to the tissue, heating it such that one portion of the region of mucosal tissue is maintained at a predetermined temperature range T.sub.1 while another portion of the region of mucosal tissue is at least temporarily maintained at predetermined temperature range T.sub.2.

A microneedling system may reciprocate a plurality of microneedles disposed on a handpiece into the skin of a patient. The handpiece may have a plurality of positive and negative electrodes in the form of microneedles or surface electrodes arranged across an array. The microneedles and/or electrode plates may deliver RF energy to the patient for inducing collagen coagulation and regeneration. The electrodes may be arranged such that each electrode is positioned adjacent a closest electrode of opposite polarity. There may be an uneven number of positive and negative electrodes. Central electrodes may be surrounded by at least three adjacent closest electrodes of opposite polarity. The electrodes may be arranged in a hexagonal or other polygonal manner. The electrodes may be arranged to provide uniform distribution of energy, heating, and effectively to some extent damage the entire discrete area that encloses the positive and negative electrodes.

A beauty care or skin treatment apparatus using plasma includes: a body having a handle part on which a ground is formed; an electrode unit which is formed on one surface of the body and forms atmospheric plasma by application electric power thereto; an image input unit which is provided in the body so as to photograph an image of the skin which faces the image input unit; and a transmission unit which is configured to transmit an image signal inputted from the image input unit to a terminal connected thereto.
