C. It uses a microchip to collect and supply heat, and evenly transfers the heat to the skin through infrared pulse technology, causing the proteins in mosquito saliva that cause itching to deteriorate. The pulsed photoelectric effect can also numb the skin bitten by mosquitoes, thereby reducing itching. It can effectively relieve itching in about 10 seconds and automatically stop after one-click itching relief. D. This itching-relieving device is designed to be relatively lightweight and easy to carry. The device is small in size and light in weight, suitable for use at home, during travel, and outdoors. E.
