1. A computer-implemented method of determining a location of a personal care device with respect to a skin surface of a subject, the personal care device being configured to perform a personal care treatment to the skin when in contact with the skin surface, the method comprising:
receiving data representative of a measured degree of curvature of the skin surface within a first region of the skin surface of the subject, with which the personal care device is in contact;
determining, by comparing the measured degree of curvature with curvature information for a plurality of regions of the skin surface of the subject contained in a database, an indication of a location of the first region of the skin surface on the subject; and
performing, based on the determined indication of the location of the first region, an action in respect of the personal care device.
