Dermatologists may use a laser to decrease the visibility of a scar and relieve discomfort and itching. Laser therapy can help prevent the formation of scars following the treatment. The laser helps to encourage the skin to grow fresh and healthy. While laser therapy cannot erase scars, it can render them less visible and unpleasant. Many forms of scars including surgical scars, acne scars, and injury scars can be treated with laser treatment. According to skin laser clinic Toronto, the application on the face is equally safe.

How does laser treatment help?

Laser therapy penetrates the outer skin layers to encourage the new development of healthy skin cells. The laser eliminates old, damaged skin layers so that fresh, healthy skin may develop. In essence, laser treatments create a new scar rather than an old one. The new skin should, however, develop more evenly.

Scar tissue development is a natural body reaction to damage. Scars are not detrimental and for medical reasons do not necessitate removal. However, a series of treatments can lessen their appearance and discomfort if they are unpleasant, restricting, or mentally affecting a person.

Laser therapy with scars can help by reducing:

  • Pain or itching
  • bad appearance
  • Improve the skin circulation around the scar

Doctors can select from a range of lasers that utilize varying lights and have distinct effects on the skin. Certain lasers are ablative, which means that they remove the top layer of the skin, whereas other lasers preserve the surface of the skin while impacting the underlying layers.

Certain skin tones may not be acceptable since they might lead to discolored skin. Examples of laser types used in scar therapy by doctors include:

  • nonablative fractional laser
  • ablative fractional carbon dioxide laser
  • intense pulsed light
  • 1064-nm Nd: YAG
  • Q-switched Nd: YAG
  • pulsed dye laser

Are the risks involved?

Before carrying out laser treatments, a doctor should explain potential side effects and concerns to the individual. The negative effects may depend on laser kind, scar severity, and skin tone of the individual.

A few of the most common side effects are:

  • skin infection
  • minor bleeding
  • skin crusting
  • discomfort
  • swelling
  • skin discoloration


Doctors can apply laser therapy to decrease pain, and scars appearance in single treatments, or in conjunction with other techniques. Instead of scarred skin, the laser is perfect for new, healthier skin to develop. If a person has a cosmetic look of a scar or a scar is physically inconvenient, they can discuss therapeutic alternatives with their doctor.
