As far as we know, the major manufacturers of photoelectric beauty instruments in China are: Beijing Hongqiang Beauty Equipment Instrument Factory, Guangzhou Meiyi Technology Co., Ltd., and Guangzhou Tailei Technology Co., Ltd. Before, Beijing had an advantage in producing these products, but now Beijing is also in the process of rectification. The photoelectric beauty instruments are basically produced in Guangzhou, and the instruments produced by large and small factories are difficult to see the difference on the surface, because the purchased chassis are all the same, and the main difference is that the electrical components inside the products are different.
