The light may be visible light such as red light, green light, yellow light, or the like. Light is transmitted from the cold compress assembly 200 after entering the cold compress assembly 200 and is transmitted into hair follicles under the skin to achieve hair removal.

The heat dissipation base 300 is provided at one side of the cold pack assembly 200 and is connected to the cold pack assembly 200. Because the cold compress assembly 200 can absorb heat at the skin when the cold compress assembly is attached to the skin to reduce the temperature of the skin and reduce burning sensation, the temperature of the cold compress assembly 200 can be increased when the cold compress assembly is used for a long time, and the cooling effect is reduced. The heat dissipation base 300 can absorb heat of the cold compress assembly 200, so that the cold compress assembly 200 is kept in a low-temperature working environment, and the cooling effect of the cold compress assembly 200 on skin is guaranteed. Therefore, the depilation device in the embodiment can still keep the body in a low-temperature state under the condition of continuous use, and does not cause pain to the user.
