A shaving device for skin hairs, comprising:

• a skin-contacting structure comprising a skin-contacting surface structure for contacting a portion of skin during shaving of said skin by the shaving device;
• a cutter for cutting hairs of said skin portion being contacted by said skin-contacting surface structure, said cutting taking place in a hair-cutting area defined by the shaving device;
• a shape-changing smart material of a class of materials that can reversibly change their shape and/or dimensions in a controlled way as a result of an externally applied electric stimulus and/or as a result of an externally applied thermal stimulus and/or as a result of an externally applied magnetic stimulus and/or as a result of an externally applied chemical stimulus and/or as a result of an externally applied optical stimulus;
• and
• a controller for controlling activation of the shape-changing smart material during use of the shaving device;
• wherein the shape-changing smart material is configured, arranged and effective to adapt, by means of a change of its shape and/or dimensions, a relative position and/or a relative orientation between at least part of the skin-contacting surface structure and at least part of the hair-cutting area.
