The present invention provides a laser system and laser handpiece and process for skin treatment. The system includes components for producing a continuous or pulse laser beam, and components for delivering a substance to the damaged region of skin. The system is designed to control and utilize the laser beam for damaging small volume of skin tissue and using a disposable tip to deliver a substance which is applied simultaneously or with some delay producing a combination of laser action with the action of a named substance at the same time.

According to an aspect, there is provided an apparatus for evaluating skin of a subject. The apparatus comprises a processing unit configured to receive one or more images of the skin of the subject from an imaging unit, wherein the imaging unit is arranged to obtain images of the skin of the subject; process the one or more images to determine a skin type and/or a melanin index of the skin of the subject based on one or more characteristics of a structure of a pigment network of the skin; and output a first signal indicating the determined skin type and/or melanin index.

A skin treatment device (100) comprises: a housing (101); a treatment action performer (110) arranged within the housing (101) for performing a treatment action on the user's skin (2); a speed sensor (120) for sensing a relative speed between the housing and the user's skin; a speed feedback signalling device (400); a control device (140) receiving an output signal from the speed sensor. The control device controls the speed feedback signalling device if the output signal received from the speed sensor is outside a tolerated displacement speed range (R). The tolerated displacement speed range is adapted to the skills of the user to move the device over the skin surface with a constant speed. If the user's skills are relatively low, the control device increases the magnitude of the tolerated displacement speed range.

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.

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.
