Bonjela invisible cold sore cream effectively targets cold sores, and can be used to treat & prevent cold sores from occurring. Unlike some other creams that leave a white mark, Bonjela invisible cold sore cream turns invisible when applied.
Bonjela invisible cold sore cream contains UV-Active™ which works by creating a protective film layer on the skin cells of the cold sore and prevents attachment of virus particles to the cells. Additionally, it blocks UV radiation reaching the virus which is an environmental trigger of herpes simplex virus. Thus it blocks UV radiation which helps to prevent the spread of the virus.
To treat a cold sore: use Bonjela cold sore cream at least 4 times per day until the cold sore completely disappears, typically within 4-5 days
