摘要： The invention relates to a device (100) for RF skin treatment, comprising an active electrode (1) arranged on an operational side (15) of the device and having a first skin contact surface for contact with a skin of a user, which first skin contact surface has a largest cross-sectional dimension smaller than or equal to 2 mm. The device comprises a return electrode (2) arranged on the operational side (15) of the device and having a second skin contact surface for contact with the skin of the user, wherein an area of the second skin contact surface is at least five times larger than an area of the first skin contact surface. An RF generator (21) is arranged to supply an RF treatment voltage between the active electrode (1) and the return electrode (2) so as to heat a skin region below the active electrode, wherein the RF treatment voltage has a frequency in a range of 100 MHz-3 GHz. By using a frequency of the RF treatment voltage in said range, a depth of thermal lesions voltage is considerably increased as compared to RF skin treatment devices using a comparable RF treatment voltage, but at a much lower frequency.

摘要： A measurement system is disclosed for light-based measurement of collagen, using a first light intensity and a second light intensity. The measurement system comprises a light source for emitting a light beam having a source wavelength range and an optical system to polarize light within the source wavelength range, thereby generating a polarized light beam, and to direct and focus the polarized light beam to a target position inside the skin at a predetermined focus depth below an outer surface of the skin. The measurement system further comprises a first detector, and a second detector for detecting the first light intensity and the second light intensity within, respectively, a first detection wavelength range and a second detection wavelength range of light reflected from the target position. The measurement system further comprises a comparator, coupled to the first detector and the second detector and configured and arranged to determine a difference between the first light intensity and the second light intensity. When natural collagen is present at the target position, a reflected spectrum of light of the polarized light beam reflected by said natural collagen comprises a plurality of adjacent first and second wavelength ranges, wherein in said first wavelength ranges constructive interference prevails between the polarized light beam and the natural collagen, and wherein in said second wavelength ranges destructive interference prevails between the polarized light beam and the natural collagen.

摘要： A skin treatment device for locally treating skin with light is provided that comprises a tip, a light emission element, a safety mechanism comprising an optical element and an optical element positioning structure. The optical element receives a converging light beam from the light emission element. The optical element is configured to operate as a diverging lens. The optical element positioning structure positions the optical element in a safety position, or in a treatment position when the tip is in contact with the skin to be treated, and allows movement of the optical element between both positions. In the safety position, the optical element is arranged at a position on the optical axis to generate an eye-safe light beam. In the treatment position, the optical element is arranged at another position on the optical axis to generate a treatment light beam.

摘要： The application provides a non-invasive measurement device (30) and method for the measurement of skin properties using laser light, the device comprising a probe module (70) and an imaging module (50). The application also provides a non-invasive treatment device (130, 230, 330, 430) and method comprising the measurement device/method. The probe module (70) provides a probe light beam (82) that enters the skin along the probe axis (71). The probe light beam (82) is separate from any treatment radiation beam (22), so that the probe light beam (82) can be optimized for the measurement. A more reliable skin measurement system is provided because it measures a plurality of positions along the probe axis (71), within a probe region (95). The measurement device and method may also comprise a treatment module (110) or treatment step. The skin parameters measured may then be directly used to control the treatment parameters. This results in a skin treatment device (10) being provided that is both effective and delivers reproducible results.

摘要： A method of treating a skin tissue area (3) having a skin surface (5) is provided. The method comprises the steps of: deforming the skin tissue area into a deformed shape comprising a plurality of folds (17) in the skin tissue area; arranging radiofrequency electrodes (13) in contact with the skin surface on opposite sides of the deformed skin tissue area; and, while maintaining the skin tissue area in said deformed shape, providing a spatially continuous radiofrequency energy flow between the radiofrequency electrodes on opposite sides of the deformed skin tissue area through the deformed skin tissue area, thereby heating at least a portion (19) of the deformed skin tissue area; and releasing the skin tissue area from said deformed shape, thereby deforming said heated portion (19) into a wave-shaped zone of heated skin tissue having a depth relative to the skin surface that varies between a minimum and a maximum value in a direction between said opposite sides. Accordingly, an apparatus for treating a skin tissue area (3) is provided.

摘要： In a hair styling device (20), a light emitting diode (33) is configured to deliver optical energy to hair, wherein an energy fluence of the optical energy is between 0.5 and 9 J/cm2, and more preferably between 1 and 5 J/cm2. The light emitting diode (33) is pulse-driven, and a pulse width of the optical energy is at least 50 ms. An output wavelength of the optical energy may be between 400 and 900 nm. The pulse width of the optical energy is preferably between 50 and 300 ms. The hair styling device (20) may comprise an optical shield (32) configured to block stray light during light exposure of the hair. An inner surface of the optical shield (32) may be reflective and/or may have a parabolic shape. The optical shield (32) may be movable between an open position in which a lock of hair can be placed in the hair styling device (20) while the optical energy is not applied, and a closed position in which light is prevented from escaping the hair styling device (20) while the optical energy is applied to the hair. The hair styling device may be a hair straightener having opposing first and second straightening surfaces, of which at least the first straightening surface comprises the light emitting diode (33), and at least the second straightening surface is arranged for reflecting light from the light emitting diode (33).

摘要： The invention provides a non-invasive treatment device (100) for heating a first (15) and a second (25) inner region of skin using r.f. electrical current, comprising: a first r.f. treatment electrode (10) configured and arranged to allow r.f. current to pass through the first inner region (15) to a return electrode (340), a second r.f. treatment electrode (20) configured and arranged to allow r.f. current to pass through the second inner region (25) to the return electrode (340), the device further being arranged such that the smallest distance between the first r.f. treatment electrode (10) and the return electrode (340) is less than the smallest distance between the second r.f. treatment electrode (20) and the return electrode (340); wherein the electrical skin contact area of the return electrode (340) is 5 or more times larger than the electrical skin contact area of the first r.f. treatment electrode (10), and the electrical skin contact area of the second r.f. treatment electrode (20) is 5 or more times larger than the electrical skin contact area of the first r.f. treatment electrode (10). By incorporating the second and first treatment electrodes in the same device, or probe, the positional relationship between the first and second regions being heated is fixed, or at least more predictable. By means of a suitable configuration, the regions may coincide to a smaller or greater degree. In some cases, the configuration may allow the same skin condition to be treated using heating of the first and second inner regions without moving the device over the skin. By providing an electrical skin contact area of the return electrode which is 5 or more times larger than the electrical skin contact area of the first r.f. treatment electrode, the locations heated by the r.f. electrical current will be proximate to the first treatment electrode, reducing the possibility of undesirable hotspots proximate the return electrode (340).
