In a device for use to prevent skin from sunburns according to the present invention, critical values concerning sunburns corresponding to a plurality of Sun Protection Factor values are displayed upon inputting of a user's skin-type data. Accumulative ultraviolet-radiation doses as measured over predetermined time intervals are compared with the critical values concerning sunburns corresponding to the above mentioned Sun Protection Factor values. Alarm sounds are activated calling the user's attention to prevent his or her skin from sunburns, every time each of the critical values coincides with the measured radiation doses.
