A graphene nano-steam generator and a beauty instrument are provided. The graphene nano-steam generator includes a coarse steam channel, a nano-steam channel and a high-voltage power supply device. The coarse steam channel is connected to a coarse steam manufacturing device and the nano-steam channel. The coarse steam channel is provided with a steam sieving device, and an end of the coarse steam channel is provided with a first electrode and a second electrode. The high-voltage power supply device is coupled to the first electrode and the second electrode. The high-voltage power supply device supplies high-voltage electricity to the first electrode and the second electrode, and forms a high-voltage arc discharge between the first electrode and the second electrode, thus the coarse steam molecular group flowing through is ionized by the high-voltage arc to generate a large amount of active nano-scale steam to be flowed out from the nano-steam channel.
