Abstract: The present application relates to a shaving guidance system (10) for guiding a user during a shaving procedure, the system comprising an image sensor (30) configured to register an image of a part of the body of the user, an image data analyzer (41) configured to determine a local hair-growth direction based on data in the image, a controller (40) configured to generate instructions about a direction in which a hair cutting device (20) is to be moved in dependence on the determined local hair-growth direction, and a feedback system (130) configured to provide the instructions to the user.

Abstract: The present application relates to a method for setting a cutting distance (?laser skip opt(z)) between a laser beam (14) and a skin surface (5) in a laser shaving device (1), said laser shaving device having a laser deactivation threshold (?laser_skin_opt(z)), said method comprising: operating an optical system (12) to generate the laser beam; determining a skin variation value (?) indicative of the variation in the distance of the skin surface from a reference point; determining a cutting distance between said laser beam and the skin surface in dependence on at least the laser deactivation threshold and said skin variation value; and adjusting said optical system to locate the laser beam in dependence on said determined cutting distance.
