    摘要： A device for light-based skin treatment is provided. The device comprises a light source for providing an incident light beam for treating a skin, optical elements for focusing the incident light beam in a focal point inside the skin, and a skin interface element for, during use of the device, providing optical coupling of the incident light beam from the device into the skin. The skin interface element comprises a transparent exit window for allowing the incident light beam to leave the device, on top of the exit window, a transparent mixture of a polar substance and an apolar substance, and on top of the transparent mixture, a transparent foil, the transparent foil being more hydrophobic than the exit window.

    摘要： A coupling arrangement including a coupling member arranged on a skin contact surface of an electrode of a radio-frequency (RF) skin treatment device for electrically coupling the electrode to a user's skin. The coupling member includes a first layer and a second layer. The first layer has a first electrically conductive material configured to be arranged on the skin contact surface via one side of the first layer. The second layer has a second (different) electrically conductive material arranged on the first layer, on an opposite side of the first layer. The first layer has a thickness in a range from 10 μm to 100 μm, and the first electrically conductive material has a modulus of elasticity of at least 100 kPa. The second layer has a thickness of 10 μm or less, and the second electrically conductive material has a viscosity of 1,000 CPS or less.

    摘要： An apparatus for obtaining images for use in determining one or more properties of skin of a subject, the apparatus comprising an image sensor unit for generating an image of a skin sample, wherein the skin sample corresponds to an area of skin of the subject within a field of view, FOV, of the image sensor unit when the skin of the subject is spaced a predetermined working distance from the image sensor unit; a first light arrangement comprising one or more light sources for illuminating the skin of the subject; and a second light arrangement comprising one or more light sources for illuminating the skin of the subject. The one or more light sources in the first light arrangement are spaced from the image sensor unit and arranged such that light emitted by the light sources in the first light arrangement that is specularly reflected by a skin sample at the predetermined working distance is incident on the image sensor unit, and the one or more light sources in the second light arrangement are spaced from the image sensor unit and arranged such that light emitted by the light sources in the second light arrangement that is specularly reflected by a skin sample at the predetermined working distance is not incident on the image sensor unit.

    摘要： There is provided a device (100) for imaging skin. The device (100) comprises a light source (104) configured to emit light to illuminate the skin (102). The light source (104) has a radiation angle in a range from 5 to 40 degrees. The radiation angle is the angle at which an intensity of the light emitted by the light source (104) is half that of a maximum intensity of the light emitted by the light source (104). The device (100) also comprises an imaging sensor (108) configured to detect light reflected from the skin (102) and convert the detected light into an image of the skin (102).

    摘要： A computer-implemented method of determining a location of a personal care device with respect to a skin surface of a subject, the personal care device being configured to perform a personal care treatment to the skin when in contact with the skin surface. The method includes receiving data representative of a measured degree of curvature of the skin surface within a first region of the skin surface of the subject, with which the personal care device is in contact; determining, by comparing the measured degree of curvature with curvature information for a plurality of regions of the skin surface of the subject contained in a database, an indication of a location of the first region of the skin surface on the subject; and performing, based on the determined indication of the location of the first region, an action in respect of the personal care device. A processing apparatus, a system, a personal care device, and a computer program product are also disclosed.

    摘要： There is provided a device (100) for use in determining a hydration level of skin (102). The device (100) comprises a light source (104-1, 104-2) configured to emit light (106-1, 106-2) and a first polarizer (108-1, 108-2) arranged to polarize light (106-1, 106-2) emitted from the light source (104-1, 104-2) in a first polarization direction (110-1, 110-2) to illuminate the skin (102) with polarized light (106-1, 106-2). The device (100) comprises a second polarizer (112) arranged to polarize light (114-1, 114-2) from the skin (102) in a second polarization direction (116). The second polarization direction (116) is orientated at an angle in a range from 30 to 60 degrees with respect to the first polarization direction (110-1, 110-2). The device (100) comprises a light detector (118) configured to detect the polarized light (114-1, 114-2) from the skin (102) for use in determining a hydration level of the skin.
