A skin imaging and diagnostic method and apparatus comprising, a frame, configured to circumscribe a target tissue on the skin of a patient. An electro-optics unit of the apparatus comprising: an illuminator assembly comprising illuminating elements, configured to provide illumination light on the target tissue; an imaging optics assembly; and an image sensor assembly, comprising an image sensor, wherein the imaging optics assembly is configured to collect backscattered said illumination light from the target tissue and focus the collected backscattered illumination light on the image sensor; and the image sensor is disposed to consequently sense an image of the target tissue. A controller configured to activate illuminating elements and to capture each image from the image sensor.

Disclosed is a plasma skin care device including a handpiece, an ozone decomposition module, and a suction fan. The handpiece has a plasma generator and discharges plasma in a state in which a front end portion of the plasma generator is adjacent to skin. The ozone decomposition module is configured to receive and decompose ozone, which is generated when the plasma is discharged, from the handpiece. The suction fan is configured to draw the ozone generated in the handpiece to the ozone decomposition module by suction pressure.

A fractional handpiece and systems thereof for skin treatment include a passively Q-switched laser assembly operatively connected to a pump laser source to receive a pump laser beam having a first wavelength and a beam splitting assembly operable to split a solid beam emitted by the passively Q-switched laser assembly and form an array of micro-beams across a segment of skin. The passively Q-switched laser assembly generates a high power sub-nanosecond pulsed laser beam having a second wavelength.

The present disclosure provides a method for treating ischemic stroke by illuminating a skin surface to reduce free radical generation in subsurface target tissues (e.g., the brain following an ischemic event). The method utilizes a waveguide that receives light from a light source. The waveguide is placed adjacent a skin surface of a patient and the waveguide emits light that passes through the skin surface and illuminates a subsurface target tissue. The waveguide includes light-extracting features configured to emit light at a target angle relative to the surface tissue. That is, the light-extracting features alter a trajectory of light emitted by the waveguide, such that a larger percentage of light emitted by the light guide has an angle that is +/−25 degrees off of a center line of the light guide.

A portable hair removal device (10), comprising a head portion (30), and a housing (20) connected to one end of the head portion (30). An emitter capable of emitting light is provided in the housing (20), and the light emitted by the emitter passes through the head portion (30) and then acts on the skin for hair removal. The head portion (30) is provided with at least a phototherapy lamp (32), and light emitted by the phototherapy lamp (32) acts on the skin through the head (30) and takes care of the skin. The portable hair removal device (10) has rich functions and a good skin care effect.

Some embodiments are directed to a cellulite treatment system that contains a laser generating device. A hydrogel patch may include a region, at a first side of the hydrogel patch, to be in contact with a person's skin. The region may contain an adsorbing medium (e.g., carbon black or any other substance that would have a similar effect) that, when receiving a laser beam from the laser generating device, results in Extracorporeal Shock Wave Therapy (“ESWT”) being applied to the person's skin to treat cellulite.

An applicator comprising multiple laser assemblies connected to a power supply and a controller that switches each pulse to a different one of the laser assemblies. Each laser assembly deposits a laser spot on the skin and the result is to produce a large ‘aggregate’ spot without requiring extra power or extra lasers. In one embodiment, each pulse serves as a trigger to switch the next pulse to the next laser assembly.

A cold plasma system and method for treating a region of a biological surface is presented. In one embodiment, the system includes: a housing; an air conduit within the housing; a first electrode configured proximately along the air conduit; a second electrode configured proximately along the air conduit and opposite from the first electrode; and a source of alternating current (AC) electrically connected with the first electrode. The source of alternating current is configured to generate cold plasma in the air conduit.

A system is provided for treating a skin surface of a user, comprising: at least one light emitting source configured to focus light on a specified skin region of the user, the light being configured to treat a skin condition of the user; and a controller configured to control emission of the light onto the specified skin region of the user.

The invention relates to a body irradiating device, in particular for irradiating a body of a person or a part of a body of a person, in particular with cosmetically and hygienically useful radiation, comprising a radiation source with a base and at least one first LED chip which can emit a first radiation spectrum with a first radiation peak and at least one second LED chip which can emit a second radiation spectrum with a second radiation peak differing from the first radiation peak. A body irradiating device allowing the radiation spectrum of more than one LED chip to be combined and uniformly supplied to the human body is achieved in that the first LED chip and the second LED chip are arranged below a common lens in an LED package and can be controlled separately.
