A system for recommending ultraviolet protection for a subject's skin includes an interrogation device, an analysis device, and an output device. The interrogation device has an ultraviolet sensitive module configured to generate interrogation data based on sensed electromagnetic energy reflected by the subject's skin in response to irradiation of the subject's skin by an ultraviolet electromagnetic energy source. The analysis device is configured to receive the interrogation data from the interrogation device and generate an ultraviolet analysis, which includes a recommendation for further ultraviolet protection of the subject's skin, based at least in part on the interrogation data. The output device receives the ultraviolet analysis and outputs the recommendation for further ultraviolet protection of the subject's skin.
