This product mimics the human body's natural detox response after a mosquito bite. It uses pulse technology and controlled heat to quickly break down itch-causing substances in mosquito saliva, providing safe, reliable, and non-allergenic relief with a single touch. Featuring a built-in linear motor for vibration massage, it offers fast response, low power consumption, and soothing relief for the bite area. It promotes blood circulation to reduce itching effectively. The device uses a microchip to generate and evenly distribute heat through infrared pulse technology, neutralizing itch-inducing proteins in mosquito saliva. Pulsed photoelectric technology helps numb the bite area for additional relief. Just press the button for 8-second itch relief. The top is made of efficient MCH ceramic for quick, even heating with lower energy use compared to traditional ceramics. The skin-friendly material ensures comfort without irritation.
