Heat pen
A heat stylus (also thermal pen or bite away ) is a device for mitigating the effects of an insect sting (z. B. mosquito bite ) or insect bite.
effect
A heat pen has a ceramic plate at the tip, which heats up to 50 to 60 ° C. The heated ceramic plate is brought into contact with the skin area affected by the insect bite for 3 to 10 seconds, causing the skin to briefly heat up to 50 to 53 ° C (local hyperthermia). Different physiological processes are activated by the heat. For example, it is assumed that the insect proteins are destroyed (denatured). This relieves the symptoms, for example avoiding itching. The skin is not damaged due to the short application time. The positive effect of the heat pen was confirmed by a study.
The exact effect is not known, various mechanisms are being discussed.
The same mode of action is also used to treat cold sores .
