What about the site of the cold sore?
The invisible light that the Virulite device uses penetrates the skin relatively easily, thus the virulite can treat cold sores in the nose, inside the lip and on the face as effectively as cold sores that are present on the outside of the lips.

How can light heal a cold sore?
Tests have demonstrated that light with a specific wavelength in the non-visible spectrum acts as a catalyst, which enhances the local immune response, allowing the body to heal itself rapidly.

Why can't standing in the sunlight heal a cold sore?
Sunlight contains UV (ultraviolet light), which actually triggers cold sores to occur, so sunlight can make a cold sore worse. The level of this specific wavelength in sunlight in the UK is insufficient to be effective (even in summer).

When and how many times can a cold sore be treated?
The cold sore should be treated as soon as it becomes apparent (blister or tingling stage) and then treated again 12 hours later. In the majority of people this is an adequate treatment, however in a small percentage of people the virus takes a little longer to travel down the nerve to the skin. The therapy is only effective in the presence of the virus, thus if the cold sore appears to progress after the second treatment, it is best to treat four more times a day for 2 days. There is no limit to how many times a cold sore can be treated.

Is it safe to use on children?
