The energy from the laser does two important things in eliminating the wart.
First, the laser energy likely destroys the virus that causes the wart. Second, the laser energy eliminates the blood supply that nourishes the wart. It is also believed that the inflammation caused by the laser treatment increases the body immune response to the area, which helps in eliminating the virus.
Depending on the location and size of the wart results can take 1 – 4 treatments. Warts on the hands & feet, and large warts may take 4 or more treatments for optimal results. Laser wart treatments are performed every 4 weeks.
The most common side effects include: redness and swelling. Occasionally a blister may occur. These side effects typically are mild and resolve in 7-14 days.
