What Exactly Is Laser Therapy and How Does It Work?

Before going deep into how laser therapy works, let us first understand what it is and what are its main uses. Medical treatments that use intensive light rays of a laser are called laser therapy. Unlike other light sources, light originating from a laser is usually tuned to certain wavelengths, permitting it to be focused as strong beams. These beams are often so intense that they can be used to cut steel or shape diamonds. In medicine, laser beams allow surgeons to focus on a tiny area and work with high precision so that the damage caused to the surrounding tissue is the bare minimum. In addition to this, laser therapy causes less pain, scarring, and swelling of the tissues when compared to traditional surgery. On the other hand, laser therapy is comparatively expensive, and you may require repeated sessions to achieve the desired results.

Uses of Laser Therapy

Laser therapy has a wide range of uses which includes but are not limited to:

  • alleviate symptoms of cancer
  • removal of kidney stones
  • partial prostate removal
  • repair retinal detachment
  • increase vision
  • treat hair loss due to alopecia or aging
  • treat nerve pains

Laser beams also have a sealing effect and can be used to seal nerve endings, blood vessels, or lymph vessels if needed. In addition to this, laser therapy is also helpful to treat early stages of some cancers, including cervical cancer, vaginal cancer, penile cancer, vulvar cancer, basal cell skin cancer, and non-small cell lung cancer. However, laser therapy is also used in treatments like chemotherapy, surgery, or radiation.

In addition, some cosmetic uses of laser therapy are;

  • remove moles, birthmarks, warts, and sunspots
  • diminish the appearance of blemishes, wrinkles, or scars
  • tattoo removal
  • hair removal

Among these, laser hair removal is one of the most common cosmetic procedures in the U.S. It works by concentrating high-intensity laser beams into hair follicles. As the pigment in the follicles absorbs the laser, it destroys the hair. See Also: What Is Laser Liposuction, and Does It Help to Reduce Weight?

Benefits of Laser Hair Removal

Lasers are very useful when it comes to hair removal. They help remove and prevent the growth of unwanted hair from various body parts such as the face, back, arm, leg, chin, bikini line, underarm, and other areas. Some of the main advantages of laser hair removal are,

  • Precision – Laser beams are highly precise, which let them selectively target coarse, dark hairs and leave the nearby skin undamaged.
  • Speed – Laser therapy offers unmatched speed to hair removal because each laser pulse takes a fraction of a second to treat several hairs simultaneously.
  • Predictability – Laser therapy for hair removal is more predictable since most patients can experience permanent hair loss after three to seven sessions.

How Does Laser Therapy Work?

The process behind laser therapy is called photobiomodulation. When the laser is activated, it generates a beam close to an infrared frequency. This beam, when absorbed by your body’s cells, causes a series of events to happen, resulting in an intensified generation of cellular energy. With this enhanced energy, the body can handle inflammation better and improve the cleaning up of damaged cells. This results in increased blood circulation, a decrease in inflammation, and improved healing. See Also: Does Laser Treatment Help with Scarring?

What Will You Experience During Laser Therapy?

While undergoing laser therapy, you will feel the warmth of the laser beam and see a red light. You will not experience any drastic amount of pain, but if you do feel pain during laser therapy, let the specialist know so that the intensity of the application can be modified.

Treatment Results of the Laser Therapy

  • Reduced inflammation in the target area
  • Improves joint flexibility and mobility
  • Pain relief due to the reduced inflammation
  • Reduces muscle spasms and tightness
  • Speed up recovery times

Cautions to Be Observed While Undergoing Laser Therapy

You need to be cautious while undergoing laser therapy if you have tattoos on your body. This is because the ink used to make tattoos can heat up faster than normal skin tissue, and it increases the chances of a burn. Therefore, adjustments may have to be made while using laser therapy on tattooed areas to minimize discomfort. Another aspect to be considered while undergoing laser therapy is skin sensitivity because certain medications can increase the photosensitivity of the patient, which can increase the risk for burns during the therapy. See Also: Which Laser Treatment Is Best for Face Skin Lightening?
