    Abstract: 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.

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.

    Abstract: 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.
