How HERPOtherm® Works On Preventing Cold Sore Blisters


HERPOtherm® works by applying 51° heat (local hyperthermia) on the cold sore, which then releases degradation enzymes and histamine and thus reduces the inflammatory reaction.

This is a physical action based on a brief, concentrated application of heat to a small, limited area of skin. A localised pulse of heat may be sufficient to relieve symptoms such as itching, burning, tingling or tightness.

HERPOtherm® is completely free from chemicals, and therefore is suitable for the treatment of cold sores in allergy sufferers, pregnant women and children over the age of 12.

  • HERPOtherm® can prevent the development of cold sore blisters, if applied early enough
  • If applied later, the severity of symptoms may be lessened, or they may fade sooner

    How To Use HERPOtherm®





    HERPOtherm® is very simple to use. First place the device onto the affected area and gently press it on to the skin. After pressing the button, the ceramic contact surface heats up to approx. 51°C. This temperature is maintained for three seconds, when HERPOtherm® then switches off automatically.

    Note: To achieve maximum heat transfer to the skin, please ensure good contact with the skin, as even a small air gap can affect heat conduction.

    Please leave a treatment interval of at least 2 minutes between each application. Do not exceed a maximum number of 5 applications per hour on the same skin area.
