Laser/light Therapy for Skin Lesions

Laser/light therapy is a non-toxic and non-invasive therapy that uses light energy to repair and regenerate skin cells. The procedure reduces the need for medication, improves the outcomes for skin conditions treated and increases the recovery rates of affected tissues.

What you should know about laser/light therapy for skin lesions

During laser/light therapy, a low-level laser, usually red, is applied to the lesion. The laser transmits photons about three inches into the skin. Mitochondria in the skin membranes absorb the red laser light, causing an increase of adenosine triphosphate levels, leading to an increase in healthy cell production. The process also promotes healing by increasing production of collagen, enzymes and cell growth. The increased collagen production helps prevent scar tissue from forming.

Possible risks

As with any treatment, there are risks associated with it, though they are minimized in the hands of a qualified ASDS dermatologist. These include:

  • Pain
  • Swelling
  • Discoloration
  • Bleeding
  • Infection
  • Scarring
  • Crusting

Why choose laser/light therapy for skin lesions

Benefits of laser/light therapy include:

  • Less need for pain medication following treatment.
  • Increased energy for cells in the treatment area.
  • Improved immune response.
  • Improved healing response.
  • Promotion of collagen for new skin production.
  • Better lymphatic drainage, leading to reduced swelling.
  • Improved blood circulation in treatment area.
  • Reduced inflammation.

How to prepare for the procedure

Before the procedure, an ASDS dermatologist will usually review the patient’s medical history and conduct a physical exam. This is the time for the doctor and patient to discuss expectations, potential risks and outcomes of the procedure. Patients also should:

  • Avoid sunbathing, tanning beds, waxing, chemical peels or collagen injections for two weeks prior to the procedure.
  • Avoid perfumes, deodorants or any potential irritants in the treatment area before and after treatment.
  • Avoid aspirin, anti-inflammatory drugs and herbal supplements due to increased risk of bleeding.

In addition, patients should:

  • Avoid applying makeup or lotion to the treated area for either 24 hours or until all signs of redness and stinging have dissipated.
  • Apply a good moisturizing lotion to the treated area twice daily for the duration of the treatments and for at least three months after final treatment.
