A rotation joint which is adapted for connecting a steamer arm to a facial steamer machine includes a clamping mount affixed to the facial steamer machine, an arm head which is affixed to the steamer arm having a head sleeve rotatably mounted in the clamping mount, a stopper device for limiting the rotation angle of the steamer arm, and a locking means for fastening the steamer arm to a desired inclined angle. The rotation joint limits the adjustable rotation angle of the facial steamer arm to less than 180 degree, so that the steamer arm is blocked to avoid positioning horizontally. In other words, in all situation during operation, the steamer arm extends upwards to prevent any hot water from dropping down to the patient body. Besides, the rotation joint also enables the steamer arm to be adjusted to a hang down position so as to save the storage space when it is not in use.
