The invention discloses a skin irradiation treatment apparatus comprising an annular irradiation device and a bed arranged in the annular irradiation device, an inner wall of the annular irradiation device is provided with a guide rail matched with the bed, the bed is enabled to slide on the guide rail, an annular inner wall of the annular irradiation device is provided with an annular rail, a bar-shaped irradiation device is arranged on the annular rail, the irradiation device is connected with a stepping motor, one side of the annular irradiation device is sealed while the other side is opened, a bed plate of the bed is a transparent glass plate, and the stepping motor is connected with a control panel on an outer wall of the annular irradiation device. Via design of the skin irradiation treatment apparatus, when a people lies on the bed, all-around human body skin irradiation treatment can be realized after the irradiation device revolves around a human body once, a problem that a conventional suspension type/sitting type irradiation treatment device requires a standing/sitting treatment mode can be overcome, surrounding type treatment is adopted via a bar-shaped irradiation device, and human eyes can be prevented from being stimulated by full wall type irradiation.
