The first is a -59°C treatment that uses a liquid refrigerant which is normally Zeta
Clear Review sprayed onto the skin via an aerosol can. The second is a -200°C treatment that uses liquid nitrogen normally contained within a solid metal probe that is applied to the skin's surface. Both methods will deep freeze the skin causing the lesion to blister. Care should be taken with this method as it can be extremely painful for the patient both in its application and with any post-operative wound.
With laser therapy, a high powered laser is used to burn the virus using a high-energy light beam. The most common laser is the long-pulsed Nd:YAG Laser that kills the wart with heat in a conical shape. The great thing about this laser is it does not leave any scar tissue. Electrotherapy uses electricity to create a burning hot wire which is then used on the skin to scoop the lesion out and cauterise the flesh. This method also known as radiolase, can be very effective in that it reduces the amount of bleeding often associated with plantar warts removal but it requires a local anaesthetic as the treatment can be very painful, and will require dressing and post-operative care to preventing infection.
This involves using acids to chemically burn the virus such as trichloroacetic acid. These acids are very powerful and can be very dangerous, not to say messy so generally are less commonly used today, Some of the older treatments using an acid paste were applied to the affected area and left for a period of time (often a week) before removal. The patient must be aware that any of the methods above may cause permanent scarring after treatment due to their invasive nature but generally the post-operative results can be quite encouraging.
The most common self treatment option for foot warts are over-the-counter salacylic acid preparations. There are many of these kinds of preparations available and they come in different strengths depending on a patients age and circuitry condition, so it is always wise to consult your pharmacist, doctor or podiatrist before choosing or commencing treatment. Salacylic acid preparations will chemically burn the skin surface but can be indiscriminate attacking not only the virus but also the surrounding healthy skin. They may also be messy and difficult to use unless a gel-based preparation which dries quickly can be applied.
