System comprising sensor (100) for measuring skin parameter, the sensor comprising (i) plurality of spatially separated light sources (110) to provide light source light (111), (ii) detector (120) configured at a first distance (d1) from each light source, wherein the sensor (100) provides the light source light with optical axes (OL) under an angle of incidence (a) selected from 10-80°, with the skin at second distance (d2) and to detect reflected light source light, wherein the sensor comprises at least three light sources, wherein the light sources provide unpolarized visible light source light (111), wherein the first distance (d1) is selected from 10-80 mm, wherein the detector detects polarized light, the system further comprises an analysis system generating a corresponding skin sensor value in dependence of a sensor signal of the sensor, wherein the system creates an image (1000) of the skin with the detector, wherein the image comprises a first area (1001) wherein a maximum intensity is sensed and a second area (1002) at a first image distance (1003) from the first area (1001), wherein the first and second area do not overlap, the system further generates the skin sensor value based on an intensity dependent of the reflected light source light along a path (1004) between the first area (1001) and the second area (1002).
