A 78 year old man with fair skin was referred to our clinic for treatment of skin tumours limited to the left side of his face. Histological examination showed that the tumours were of the types predominantly induced by ultraviolet radiation. Since the early 1970s, he had frequently spent several weeks a year on holiday in Spain, driving in an air conditioned car with the windows closed. While ultraviolet B irradiation is completely blocked by window glass, ultraviolet A is barely absorbed. Therefore, we strongly recommend the use of sunscreens blocking both wavelengths in sunny areas even when travelling in cars with windows closed.
