Could Botox beat cold sores?
It is hoped that Botox could be used as a way of beating cold sores in the future.
Scientists at the Chicago Centre for Facial Plastic Surgery in the US have been testing the substance on sufferers of the condition in the hope that it could prevent the herpes simplex virus from getting to the surface, the Daily Mail reports.
Participants will be given an injection of Botox every three months for a year to see whether it could become a valid treatment.
Researchers believe the Botox will be able to block the nerve in which the virus lies dormant without affecting other areas of the face, stopping it from coming back.
Infection with the cold sore virus usually occurs in childhood and some people go on to suffer from them regularly, particularly when they are under stress or have had an illness.
The virus hides in the nerve root until activated, whereupon it produces a painful, itchy red sore on the lip.
