The machine works by using a probe to fire microwaves into the infected tissue, the probe has an individual head that is discarded after every treatment. Prior to treatment, it is sometimes necessary to debride the verruca, meaning that any hard skin is removed from the top of it. The probe is then applied directly to the skin for microwave therapy.
 
The microwaves superheat the skin cells and cause a small amount of cell damage to the area. The idea is that we are provoking an immune reaction from your body. The HPV virus is extremely stubborn, your own body has a difficult time recognising that the cells in the foot are infected. Research shows that to get the best result from SWIFT microwave therapy, completing the course over three treatments is key. After the first treatment, the next 2 treatments are spaced 4 weeks apart. After the 3rd treatment, we wait 14 weeks before the review. This evidence-based treatment plan is proven that at the 4-week intervals, the microwave therapy is intercepting the production of newly infected cells before they have matured. On occasion there is a need for more than three treatments, 4th and 5th treatments have proven highly successful.
