Thanks to heat it®, you can treat itchy insect bites at any time and in just a few moments using your smartphone.

Treatment duration

The treatment duration can be selected from 4, 7 or 9 seconds (short, medium, long).

This mode is suitable for children from 3 years of age and for adults with sensitive skin. The treatment temperature is reduced by 3 °C.

Sensitive skin

For the treatment of particularly sensitive skin areas, the treatment temperature can be reduced by 2 °C.

Just heat it!

After clicking Start, the ceramic contact surface of the heat it® heats up to the selected temperature in a few seconds. The app tells you when you can apply heat it® to the bite and when the treatment is complete.

You can adjust the treatment individually to your personal sensitivity. Therefore, heat it® is also perfect for children from 3 years (self-application from 12 years).


Results in 3 steps

Treat insect bites within moments with your smartphone. Simply plug heat it® into the charging port and the corresponding app opens. If necessary, you can now customise the treatment. After a short warm up, the contact surface of the heat it® is placed on the insect bite. Depending on the setting in the app, the treatment takes 4, 7 or 9 seconds and reaches a temperature of between 47 and 52 °C. The app tells you once the treatment is successfully completed.

Reliable & uncomplicated

The principle of heat it®

To relieve itching and pain, the affected skin area is briefly heated to approx. 51 °C. The nerves in the skin react to this heat impulse. Current research suggests, heat application reduces the transmission of stimuli. Therefore, the itching signal can no longer be transmitted properly and the need to scratch disappears. In order to achieve this itch-relief effect on the skin nerves, a short heat pain is necessary. This medically proven principle of hyperthermia can be used for mosquito, horsefly, bee and wasp stings.

For the clinical evaluation as a certified medical device, we worked together with Prof Maurer from Charité Berlin. In June 2023, we published the world's most detailed study on the effectiveness of thermal insect bite healers.
