The rotary adjustable raw material culture equipment for cosmetic production comprises a mounting shell, an LED lamp, aservo motor, a first rotating shaft and the like, wherein the LED lamp is fixedly mounted on one side face of the top of the mounting shell, and the servo motor is fixedly mounted on one side face ofthe bottom of the mounting shell. According to the culture equipment, plant tissues in the culture dish can be uniformly irradiated by lamplight, so that the plant tissues grow better, the plant tissues can be prevented from being burnt by the lamplight under long-time lamplight irradiation, and meanwhile, the requirements of different plant tissue culture on the lamplight irradiation intensity can be met.
