The present invention relates to a light emitting device for providing dermatological treatment. The present invention comprises a housing structure for housing a light emitting source, a fan and a duct. The light emitting source is arranged to emit light energy to external of the device and the fan is configured for directing air heated by operation of the light emitting source into the duct. The duct is arranged to direct heated air in an airstream pathway from an outlet port of a distal end of the duct and through an aperture in the housing structure where the housing structure and the duct are relatively arranged such that no part of the housing structure extends into the air stream pathway in order to minimise heat exchange from the heated air to the housing structure.

The present application relates to an optical system (1) comprising a plurality of optical components, a pulse generating arrangement (3) configured to generate a treatment pulse along a treatment pulse optical path through said optical components, said pulse generating arrangement also being configured to generate a probe pulse along a probe pulse optical path extending through said optical components, a sensor (8) configured to generate information indicative of an optical characteristic of said probe pulse that has passed along said probe pulse optical path through said optical components, and a controller (5) configured to control said pulse generating apparatus (3) to selectively emit said treatment pulse along said treatment pulse optical path (2), in dependence on the information generated by the sensor (8).

In one aspect, devices for light treatment of skin are described herein. A device described herein, in some embodiments, comprises an interior compartment having a proximal end and a distal end, and an optical aperture disposed at the distal end. The device also comprises a laser or BBL source that produces a laser or BBL beam. The laser or BBL beam has a first optical path within the interior compartment, between the proximal end and the distal end. Additionally, the first optical path exits the interior compartment through the optical aperture. The device further comprises a camera that receives light from the aperture. The light received from the aperture has a second optical path within the interior compartment. Further, a selectively reflective optical element is disposed in the first and second optical paths. The selectively reflective optical element generally transmits the laser or BBL beam but generally reflects at least a portion of the light from the aperture toward the camera.

A device for enhancement of visual appearance including a first applicator to be coupled to a first area of a body region, with a first magnetic field generating device and a first radiofrequency electrode, a second applicator to be coupled to a second area of the body region, with a second magnetic field generating device. The device further includes a first energy storage device, a second energy storage device, and a first switching device to discharge energy from the first energy storage device to the first magnetic field generating to generate a first time-varying magnetic field to cause muscle contraction, and a second switching to discharge energy from the second energy storage device to the second magnetic field generating device to generate a second time-varying magnetic field. The first radiofrequency electrode may provide first radiofrequency waves causing heating of tissue within the first area of the body region.

The present disclosure discloses a depilator including a head portion and a hand-held portion. The head portion includes a cold compressing portion and an illuminating portion. The illuminating portion is configured for emitting light for caring for a skin of a user. The hand-held portion includes a hair removal device, a heat conducting portion and a cool driving portion. The hair removal device emits light to the cold compressing portion. The heat conducting portion absorbs heat of the cold compressing portion. The cool driving portion drives the external cooling medium to take away the heat of the heat conducting portion. The cold compressing portion emits light to irradiate the hair follicles of the skin of the user, and uses the light to penetrate the skin to irradiate the hair follicles for hair removal. Therefore, the hair device has both functions of hair removal and skin care.

A cooling device for removing heat from subcutaneous lipid-rich cells of a subject having skin is provided. The cooling device includes a plurality of cooling elements movable relative to each other to conform to the contour's of the subject's skin. The cooling elements have a plurality of controllable thermoelectric coolers. The cooling elements can be controlled to provide a time-varying cooling profile in a predetermined sequence, can be controlled to provide a spatial cooling profile in a selected pattern, or can be adjusted to maintain constant process parameters, or can be controlled to provide a combination thereof.
