Laser - Treatment, Procedure And Side Effects

Last Updated: Dec 15, 2021

What is the treatment?

A relatively new form of medical treatment, laser therapy makes use of focused light. The full form of LASER is light amplification by stimulated emission of radiation. In this type of treatment, the light is effectively tuned, using specific wavelengths to create controlling beams.

As a form of medical treatment, the laser is used for precision, wherein specific areas of the body are subjected to the beam in order to prevent the surrounding area from damage. As compared to traditional forms of surgery, laser treatment results in less pain and faster recovery. But it can be expensive and multiple sessions may be necessary.

Laser therapy is used to treat a number of medical problems like-

  • Malignant or non-malignant tumors and polyps: They are either shrunk or completely destroyed.
  • Cancer symptoms
  • Kidney stones
  • Treat detached retina
  • Vision improvement
  • Nerve pain of the back

Laser treatment is also a popular cosmetic procedure, used to remove warts and birthmarks as well as sun spots. Laser treatment for hair removal is also very popular. Many individuals also opt for laser therapy to get rid of tattoos and wrinkles on the face.

How is the treatment done?

Before undergoing Laser Treatment one needs to ensure that they understand the implications of the therapy. Doubts and questions should be cleared with the doctor before undergoing the treatment. Pre-treatment planning should be done to ensure that someone is available to drive you home and you have enough time to recover thereafter.

Certain medications may be discontinued a few days prior to the commencement of the treatment process. This is done to prevent the effect of blood thinners.

The technique of laser therapy that is used for treatment generally depends on the problem that is being treated. For instance, in the case of laser therapy to treat a tumor, an endoscope is first inserted into the body to view the tumor. The laser is then aimed at the tumor and concentrated light beams are used to destroy or shrink the tumor.

In the case of cosmetic treatments, the laser is applied directly to the skin.

Different lasers are used to treat different medical conditions, for instance, carbon dioxide lasers treat superficial cancers. Skin cancer is an example of superficial cancer.

How long does laser skin treatment last?

The results of the treatment and its duration not only depend on the type of laser Treatment but also depends on your skin condition that is supposed to be addressed during the treatment. For instance, if one needs to remove the sunburn out of their skin, your doctor asks the duration of the damage that has been embedded on your skin and then looks for the best option. In general cases, most of the laser Treatments last long for three to five years.

Can I use Vitamin C after laser?

The advised amount of vitamin C concentrate can help you keep all the pathogens including free radicals away from your skin. It is advisable to use it in the form of serum after gently cleansing your skin to hydrate.
