Abstract

This article deals with the immediate effect of infra-red (IR) irradiation on human skin. The cutaneous response to IR significantly differed from that to polychromatic UV rays. The IR erythema showed a reticular pattern and was monophasic. Minimal erythema (ME) appeared without latency and faded a few minutes later. Induction of IR-ME required a radiation doses about 15,000 times higher (187-295 J/m2) than was needed for UVB erythema. The maximum erythema also occurred immediately after exposure to IR and faded away within one to four hours. The response was biphasic in only one of 28 test persons. Histological studies revealed dilated vessels and perivascular accumulation of degranulated mast cells.
