The invention provides a system (1) comprising a sensor (100) for measuring a skin parameter, the sensor (100) comprising (i) a plurality of spatially separated light sources (110) configured to provide light source light (111), and (ii) a detector (120) configured at a first distance (d1) from each of the light sources (110), wherein the sensor (100) is configured to provide the light source light (111) with optical axes (OL) under an angle of incidence (α) selected from the range of 10-80° with the skin at a second distance (d2) and to detect reflected light source light (111), wherein the sensor (100) comprises at least three light sources (110), wherein the light sources (110) are configured to provide unpolarized visible light source light (111), wherein the first distance (d1) is selected from the range of 10-80 mm, wherein the detector (120) is configured to detect polarized light, and wherein the system (1) further comprises an analysis system (2) wherein the analysis system (2) is configured to generate a corresponding skin sensor value in dependence of a sensor signal of the sensor (100), wherein the system (1) is configured to create an image (1000) of the skin with the detector (120), wherein the image (1000) of the skin 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 area (1001) and second area (1002) do not overlap, wherein the system (1) is further configured to generate the skin sensor value based on an intensity dependent of the reflected light source light (111) along a path (1004) between the first area (1001) and the second area (1002).
