The common wart is known as verruca vulgaris. They are caused by a viral infection of the skin. This occurs as a result of direct contact with the virus. They do not spread through the blood stream and occur more commonly in children than adults. When they occur on the bottom of the foot, they are called plantar warts. There are various available treatments for warts, including topical solutions and cryotherapy. While these options can be effective, warts persist despite use of these treatments. Some people may have specific difficulties with these treatment options including the inconvenience of frequency and length of time that topical solutions may need to be applied. But another highly effective treatment option is now available! Laser treatment has been shown to have a high success rate in clearing warts, including warts that may have been previously unresponsive to other treatments. In a study involving 348 people, a 96% success rate was achieved in clearing warts using the GenesisPlus laser system (1). These are very promising results, when compared with other studies of cryotherapy for example, that have reported clearance rates below 70% (1).
How does laser treatment remove warts?
Blood vessels are a characteristic feature of warts and help to maintain growth of warts. It is believed that the laser pulse is absorbed by these blood vessels, causing destruction of blood vessels to the warts. This deprives nutrient supply to the wart, thus impeding further growth of virus-containing skin cells.
How many treatment sessions are required?
Treatments take about 15-30 minutes. The number of laser treatment sessions that are required to remove warts will depend on the size and depth of the warts. More superficial warts may be eradicated successfully with only one treatment session, while deeper warts may require up to 4 sessions.
