1. A device for measuring at least one skin parameter of skin, the device comprising:
a housing structure defining an interior cavity and a first opening at a skin contact end of the interior cavity;
a movable part connected to the housing structure via an elastic connecting arrangement, the movable part being movable with respect to the housing structure such that the movable part at least partly remains within the housing structure and configured to protrude from the first opening when no external force is applied to the movable part, the movable part comprising a front end section for contacting a skin surface of the skin and a second opening through the front end section;
an optical sensor for measuring a first skin parameter of the skin, the optical sensor being provided within the interior cavity of the housing structure and comprising an illuminating unit for illuminating the skin surface by emitting light through the second opening of the movable part and a camera, having a focal area, for acquiring an image of the skin based on light reflected by the illuminated skin surface;
a plurality of electrical contacts for measuring a second skin parameter of the skin, wherein the plurality of electrical contacts are arranged on the front end section of the movable part around a perimeter of the second opening; and
a trigger for detecting a relative position of the movable part with respect to the housing structure, and for triggering the measuring of the first skin parameter by the optical sensor when a predefined relative position is detected, wherein the predefined relative position ensures that the skin surface of the skin is in the focal area of the camera.
