The effect of medical laser on scars
Medical laser is considered one of the favorite cosmetic solutions of some dermatologists, because it is able to penetrate the layers of the skin safely and stimulate cell regeneration and rid the skin of dead cells.
As for the treatment of scars by laser, the treatment mechanism here mainly depends on creating a new scar in the skin at the place of the old scar, in order to stimulate the skin to regenerate its cells in the area of the scar and thus significantly reduce the appearance of the old scar.
Laser scar treatment may help:
Reducing any redness or itching in the place of the scar.
Improve the appearance of the scar and make it less visible to the beholder's eye.
Improving the ability to move the affected area of the scar, especially when the scar is spreading over a relatively large area of skin as is the case with burn scars.
Types of lasers used to treat scars
Before starting to treat scars with laser, the doctor usually discusses the options available from different types of lasers, before agreeing with the patient on the appropriate type of case. Here is a list of the most important types and techniques of laser used to treat scars:
1- Nonablative Fractional Laser
The patient needs several sessions here to obtain the required results. This type of laser usually causes redness, swelling and slight peeling in the skin, symptoms that all fade within several days.
2- Ablative Fractional Resurfacing
The patient here needs fewer sessions than he may undergo in the previous type, but the recovery period for this type of laser is longer and the associated side effects are more severe.
3- Pulsed Dye Laser Technology
This type of laser treatment is usually used to cut the blood supply to the scar area and thus reduce its redness and prevent the increase in its size, which is a good option for keloid scars.
4- Other types and technologies
Not only do the types of lasers used to treat scars stop, but they extend to the following other types:
Carbon Dioxide Laser.
Intense Pulsed Light - ILP.
Sometimes more than one of the above techniques is combined during the unit session or during the different treatment stages.
