A treatment device for fractional laser-based skin treatment includes an emission window having an elongated area and predefined locations that are arranged in an elongated array which extends along a treatment axis of the window. A treatment generator has a treatment laser for emitting laser light towards skin tissue from the predefined locations in the emission window for generating, in use, laser-based lesions inside the skin tissue. The treatment device also includes a motion sensor for sensing motion of the treatment device relative to the skin surface, and a controller for determining a non-zero sequence of at least one of the predefined locations from which laser light is consecutively emitted in dependence on the sensed motion. The controller allows generation of the non-zero sequence when the sensed motion of the treatment device relative to the skin surface only has a component in a direction parallel to the treatment axis.

Device for fractional laser-based-treatment

A skin treatment device comprising a light source providing a light beam for optically treating skin, a wheel with a wheel surface for reflecting the light beam towards the skin, driving means for rotating the wheel and changing an angular position of the wheel, where different angular positions of the wheel correspond to different directions of reflection for the light beam, an angular position detector for detecting the angular position of the wheel, storage means for storing predefined skin-treatment patterns, a relation between the different angular positions of the wheel; and different reflection directions of the light beam, a control circuit coupled to the light source. The light source being controlled in dependence on the detected angular position such that, for each revolution of the wheel, the light beam is controlled to only illuminate the wheel surface in selected angular positions of the wheel to realize a predefined skin-treatment pattern.

Skin treatment device

The present application relates to a microdermabrasion device (). The device has a suction path () along which skin fragments removed by the device are drawn, and a detection unit () configured to determine one or more characteristics of skin fragments drawn along the suction path. The detection unit is configured to determine the depth of abrasion performed by the device based on the one or more characteristics of skin fragments drawn along the suction path. The present application also relates to a method of determining the operating depth of abrasion of a microdermabrasion device.
