Disclosed is a high power VCSEL laser treatment device with a skin cooling function, comprising VCSEL array (4) packaged on a laser heat sink (2), an optical transmission device (8) arranged in front of light-exiting faces of the VCSEL array (4) and a high-heat-conductivity optical window sheet (6) adhered to the light-exiting port end of the optical transmission device (8). An integrally molded cooling conduction metal piece (1) is arranged on the outer sides of the laser heat sink (2), the optical transmission device (8) and the high-heat-conductivity optical window sheet (6). In addition, one or more semiconductor chilling plates (7) are arranged between the cooling conduction metal piece (1) and the laser heat sink (2).

Radiofrequency (RF) skin treatment devices and methods are provided herein. RF energy is delivered via electrodes in a phase-controlled manner which heats skin volumes below the surface more than the skin surface itself. At least one electrode at least partially encloses at least one other electrode. The combination of controlling the phases of the RF energy delivered to different electrodes and the enclosing configuration of the electrodes allows concentrating the delivered energy in specific regions below the skin surface at a particularly high efficiency. Configurations of the enclosing and the enclosed electrodes, their forms and combinations with other electrodes and the phase polarities applied to the electrodes are also provided.

A method for photothermolysis that includes applying galvanic current energy to skin at an area of a hair follicle and applying pulsed optical energy to the skin at the area of the hair follicle at an energy level and duration so as to cause thermal destruction of a hair papilla.

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.

A plasma torch having an open end from which a plasma plume is emitted in use is disclosed. The plasma torch includes a central cathode rod, a grounded conductive tube having an open end and being arranged around the cathode and spaced therefrom to form a first cylindrical cavity open at one end; and a high voltage electrode having a dielectric barrier material at a radially inward-facing surface thereof and being arranged around the grounded conductive tube and spaced apart therefrom to form a second annular cylindrical cavity open at one end. A constant direct current (DC) electrical power plus a high voltage pulsed electrical power is provided to the cathode producing an arc discharge in the first cavity between the cathode and grounded tube to generate a central thermal plasma emitted at an open end of the first cylindrical cavity. A high voltage alternating current electrical power or pulsed electrical power is provided to the high voltage electrode producing a dielectric barrier discharge in the second annular cylindrical cavity to generate a non-thermal plasma emitted from an open end of the second cavity as a halo around the central thermal plasma.

A portable hair-removal apparatus (1) is provided, which includes an air-suction mechanism (10). The air-suction mechanism (10) includes a heat-generating assembly (101) and a heat-dissipation housing (102). The heat-dissipation housing (102) is provided with an air outlet (1021). The heat-generating assembly (101) is connected to the heat-dissipation housing (102) and defines at least one air inlet (1022). External air is sucked into the heat-dissipation housing (102) via the air inlet (1022), flows through the heat-generating assembly (101) to reduce the temperature thereof, and is discharged via the air outlet (1021). A short-range air-passing channel is formed by means of the cooperation of multiple components, such that the heat dissipation performance is improved, the size is further reduced by simplifying the internal structure and the portability is improved.

A skin treatment device having a treatment window for treating skin through the treatment window and a user guide to deliver a tactile feedback signal during movement in stepwise increments of the treatment window along the skin.

Non-thermal Atmospheric Plasma (NAP) from a plasma source is mixed with a liquid medium and the resulting compound is applied to the scalp to treat hair loss. The NAP-medium compound may be applied to the surface of the scalp, or produced in situ, or injected into the scalp.
