It’s estimated that nearly 70% of people carry the virus which causes cold sores but for some it lays dormant without causing an outbreak. For regular sufferers topical creams offer some relief but generally only speed up the healing.
Herpotherm is a remarkable device which can if used early enough actually stop the coldsore forming. It uses a short blast of mild heat which triggers an immune response which often stops a coldsore in its tracks. The good news is that it might mean you’ll never need to apply old sore cream again as its reusable making it super eco-friendly!
