Product Description: This device uses pulse technology and temperature control to help soothe skin irritation after insect bites. It features a built-in linear motor for vibration massage, providing comfort and fast response with low power consumption. The massage function helps reduce itching and promotes effective blood circulation in the affected area. Equipped with microchip technology, it generates controlled heat delivered evenly through infrared pulse technology, helping to neutralize proteins in insect saliva that cause itching. The pulse photoelectric effect helps soothe insect bite areas to reduce discomfort. The device provides quick relief with one-touch operation, effectively reducing itching within seconds.
