A method of treatment of skin tissue with two laser devices of unequal wavelengths comprising the steps of: (1) activating the two laser devices simultaneously to produce two laser beams of unequal wavelength; (2) directing the two laser beams into a handpiece having a distal tip to direct the laser beams onto the skin tissue; (3) directing the two laser beams within the handpiece to an adjustable beam deflector; and, (4) the adjustable beam deflector directing the two laser beams onto the skin tissue to produce a pattern of laser spots simultaneously but separated from one another.

A method for providing localized heating of the dermal layers of skin of a patient, using energy in the form of a group of pulses having defined parameters in a controlled manner. This method preferably uses an optical delivery system to deliver pulsed energy to a specific spot of skin so that targeted layers of the affected skin are heated to a desired temperature range. The temperature range is optimally selected to maximize treatment efficacy while minimizing pain to the patient. Example applications include reducing wrinkles, acne, hair, scar tissue, warts, and promoting wound healing. In this method, the temperature of the selected locus rises quickly to the desired temperature range, then is maintained within a controlled range with a relatively flat temperature profile. The method maintains the temperature by controlling one or more of a pulse energy intensity, pulse width, and pulse frequency or time delay between pulses.

A device configured to cut hair using laser light includes a handle portion and a shaving portion. The handle portion includes a battery and a laser light source. The laser light source is coupled to and configured to receive power from the battery. The laser light source is also configured to generate laser light having a wavelength selected to target a predetermined chromophore to effectively cut a hair shaft. The shaving portion includes a support and a single fiber optic supported by the support. The fiber optic has a proximal end, a distal end, an outer wall, and a cutting region positioned towards the distal end and extending along a portion of the side wall. The fiber optic is positioned to receive the laser light from the laser light source at the proximal end, conduct the laser light from the proximal end toward the distal end, and emit the light out of the cutting region and toward hair when the cutting region is brought in contact with the hair.

Embodiments of the present invention generally relate to methods, devices, and systems for reducing a pigmentation of a skin of a patient. In some embodiments, freezing of the skin may be desirable to effect the hypopigmentation of the skin of the patient. Generally, embodiments may limit supercooling (or promote freezing) of the skin of the patient during a cooling treatment. In some embodiments, coupling fluids are provided to reduce a thermal contact resistance between a cooling treatment probe and the skin of the patient to improve cooling treatment. Optionally, a fluid carrier may be provided to help retain the coupling fluid at the treatment site. In some embodiments, the coupling fluid may include ice nucleating agents to promote ice crystal formation in the coupling fluid during cooling treatment. The ice crystal formation in the coupling fluid may progress into the skin to limit supercooling of the skin during treatment.

The present disclosure relates generally to a hair-removal apparatus, which includes a main body and a light-filtering member, with at least one sensing element disposed thereon, detachably connected to the main body. When the light-filtering member is connected to the main body, the main body recognizes the sensing element. The light-filtering member is detachably connected to the main body, so that users can easily replace the light-filtering members of different wavelengths by simply inserting and pulling, which solves the problem that functions of the existing household hair-removal devices cannot be easily switched. In addition, the sensing element is disposed on the light-filtering member, which is easy to set different combinations of the sensing elements according to multiple functions, and can mass-produce the light-filtering member to reduce the cost of production.
