The application of lasers has revolutionized the field of medical dermatology in a very big way. Since the laser is a high energy source, its use must be perfect to ensure that there are no accidents or mishaps. Laser therapy is therefore used after careful evaluation of the requirements of a person. The place of laser use is also very important.
Carbon dioxide is one of the oldest and most popular lasers used among the medical fraternity. CO₂ lasers find a wide variety of applications. The wavelength of a CO₂ laser falls between 9.4 micrometers to 10.6 micrometers. The biggest advantage of this laser is that there are a lot of variants that emit a variable range of power. Another advantage of the CO₂ laser is that the moisture of the body can easily absorb the power that a CO₂ laser emits.
CO₂ Laser applications:
- Moles: Moles are clusters of melanin absorbed on the skin over many years. It stems from melanocytes and are usually brown, pink or tan in color. They can be flat or raised, oval or round. The CO₂ laser can remove a mole without any pain. A light scab will be formed after the laser treatment but would fall off in a few days. The laser process lasts for about 90-120 seconds.
- Removal of skin tags: Skin tags are also known as acrochordon. They are smaller than a grain of rice and are mostly formed on the face, groin, neck and armpit area. While they are harmless, a person can choose to remove them if they cause irritability and discomfort or have an impact on self-esteem. CO₂ lasers find applications here as well. It takes dermatologists about2-3 minutes to remove skin tags. No trace of them would be found after the laser treatment is complete.
- Warts: Plantar warts are non-cancerous. These skin extensions occur on the sole, ball of the foot, heel and other similar places. These are basically deposits of dense fibrous tissues that are deep seated in layers of the skin. They are also visible in the softer tissues of the foot. Both common warts and plantar warts are removed in the same manner. Since these are recurring extensions, medication can only limit them but cannot be used as a permanent solution. CO₂ lasers are the most effective treatment for this condition. The laser treatment extracts the fibrous mass from deep within the skin and ensures no recurrence of the warts. It might take a couple of sessions depending on the extent and spread of the warts. Once treated successfully, the patient would get a permanent solution to this recurrent problem.
