In most cases, warts/verrucae that are treated with lasers are permanently removed after one treatment. In contrast to surgical removal, laser treatment causes no scarring and generally requires no anaesthesia.
Alternatively, an erbium laser can be used to gently remove the wart micron layer by micron layer. Clinical results show that there is no presence of the DNA of the virus that causes warts/verrucae in the plume of the laser meaning that there is no risk that the treatment will spread the virus.
