Abstract: A method and apparatus (10) to effect tanning or repair of ultraviolet-damaged DNA in humans. The method utilizes very short discrete pulses of electromagnetic radiation, with a dark period of low to zero energization between discrete pulses, of selected wave length. A first band of radiation, preferably between 250 to 400 nm, is effective to induce tanning; while a second band of radiation, preferably between 320 to 600 nm, is effective to induce DNA repair. One type of apparatus (10) continuously generates electromagnetic radiation of the selected wave length and projects that radiation through mechanical pathblockers to create the discrete pulses. Some possible mechanical pathblockers are rotating slats (41) having apertures (40); one or more rotating cylinders (20) with opening (26). An example of another type of apparatus is a stroboscopic flash tube (56).
