The abbreviation LASER stands for light amplification by stimulated emission of radiation. It works by emitting a wavelength of high-energy light, which when focused on the target area will create heat and destroy diseased cells. There are different types of lasers which can be distinguished according to the medium that produces the laser beam. One of the most popularly used lasers is the carbon dioxide (CO2) laser.
CO2 laser is a type of laser that uses a concentrated beam of light to remove or reshape skin tissue. Unlike traditional surgical methods, CO2 laser precisely targets the affected area while minimizing damage to surrounding tissue. This results in a smoother, more youthful-looking complexion. CO2 laser is perceived as a versatile and effective treatment option for a variety of skin conditions, including skin resurfacing, wrinkle reduction, scar treatment, wart removal, and the removal of benign skin growths.
The CO2 laser delivers a highly concentrated beam of light to the target area, removing or reshaping the skin as needed. The energy from the laser heats the skin tissue, causing it to vaporize and remove the outer layers of the skin. This process stimulates the production of collagen, a protein that helps to keep the skin firm and elastic. Over time, the skin will heal and reveal smoother, younger-looking skin.
Before undergoing a CO2 laser procedure, these several steps have to be followed in order to prepare for the procedure:
- Avoid sun exposure for several weeks before the procedure
- Avoid blood-thinning medications, such as aspirin or ibuprofen, for a few days before the procedure.
- Discuss any medical conditions or medications you are taking with your provider
- Avoid alcohol or caffeine on the day of the procedure.
During the actual procedure, the area to be treated will be cleaned and numbed with a local anaesthetic. The CO2 laser will then be aimed at the target area, removing or reshaping the skin as needed. The procedure may take anywhere from 30 minutes to several hours, depending on the size and location of the treatment area.
After the procedure, the treated area may be red, swollen, and covered in a protective dressing. Pain and discomfort can be managed with over-the-counter pain medication. It is important to avoid sun exposure and strenuous activities for several weeks following the procedure and to follow all aftercare instructions provided by your provider, including instructions for wound care and follow-up appointments.
CO2 laser is a safe and effective way to improve the appearance of the skin and treat a variety of skin conditions. It provides a high-precision, tissue-selective treatment with a shorter downtime (i.e. recovery time is about 2 weeks) in comparison with other procedures. However, as with any procedure, there are potential risks and side effects, so it is important to discuss these with your board-certified dermatologist before undergoing the procedure.
