This depends on how you respond to treatment.
Some resolve within three treatments but more may be needed particularly with large or multiple lesions.
These can be from 14 days to over a month apart depending on progress. Your Podiatrist will discuss this with you.
When the virus enters the skin, some people’s immune systems immediately respond by producing antibodies and killing it dead. Others don’t and verruca forms.
However, the necessary immune response can still happen at any time, and, days, weeks, months or years later, the verruca can suddenly disappear.
This is why your GP will tell you to leave it alone and it will go away in time.
Having a verruca does not mean there is anything wrong with your immune system.
Swift is designed to prompt that local immune response for the body to heal itself.
Swift treatment results in a degree of localized tissue damage prompting a healing response part of which is antibody recruitment.
It is also thought to stimulate heat stress protein production which is known to prompt a strong healing response.
Patients who are immune-suppressed are at risk of developing multiple, resistant lesions, which are difficult to treat.
