The cosmetic treatment device comprises a needle (22) whose end is introduced under the skin to the point of the varicosity. The end comprises a micro-source of heat which generates a thermal wave inside the varicosity, ensuring the thermal coagulation of the blood. The device for the cosmetic treatment of varicose veins comprises a needle (22) whose end is introduced under the skin to the point of the varicosity. The end comprises a micro-source of heat which generates a thermal wave inside the varicosity, ensuring the thermal coagulation of the blood. The needles carries current at high frequency in order to achieve heating, especially at its extremity. The needle may have a thermally insulating coating (24) covering part of its length, but not its end, ensuring the production of heat locally at the end. The frequency of the current may vary between 1 and 10 MHz. A control (26) is provided to regulate the intensity of the heat and the frequency of the current.
