Wart removal laser and freezing have their own characteristics and scope of application, there is no such thing as which method is better.
Laser is the use of CO2 laser to destroy the warts, because the laser pulse spot is smaller, so it is relatively accurate, the scope and depth is easier to control, to avoid the formation of excessive tissue damage. Laser treatment is more intensely painful than freezing, so anesthesia is required before the procedure, and freezing is generally recommended for people who are allergic to anesthesia.
Freezing utilizes the low temperature of liquid nitrogen to destroy the warts and eventually dislodge them. Because liquid nitrogen is relatively weak in controlling the depth and extent of hyperplastic swellings, multiple treatments may be required and the course of treatment is longer.
After the appearance of warts on the body, it is necessary to go to the dermatology department of the hospital in a timely manner, choose the appropriate program under the guidance of the doctor, and be operated by professionals for treatment.
