A wearable eyebrow-irradiating device includes a main irradiation body, a circumferential light-shielding lining and a fastening headband. The main irradiation body, worn on user's head, has at least one lighting component for projecting respective eyebrow-growth stimulating beams onto corresponding eyebrow-growing zones upon when the main irradiation body is fitted onto the head. The circumferential light-shielding lining, mounted fixedly at the main irradiation body by surrounding the lighting component, is to shield the eyebrow-growing zone, so that an eye can be isolated from the neighboring eyebrow-growing zone. The fastening headband, connecting the main irradiation body, is to wear the main irradiation body tightly onto the head, and to elastically deform the circumferential light-shielding lining so as to completely shield the eyebrow-growing zone and thus to prevent the eyebrow-growth stimulating beam from irradiating the eye.
