Laser Scar  reduction  uses light beams and heat to improve  scars non-invasively.

What Causes Scar Formation?

Scars occur as a result of fibrosis of the skin tissue as it heals after traumatic injury such as surgical procedures, pimple healing, infections like chicken pox, or wounds. Whenever skin gets damaged, it heals by formation of a scar. A scar is formed by the body’s attempt to throw a quick patch over the site of the wound; in order to stop bleeding; first a clot is formed at the site of the wound that is later replaced by a scar. At first, the skin that is produced by the body at the site of damaged area looks and functions differently from the rest of the body’s skin. However, with time, the body tends to replace it with skin that more closely matches the rest of the skin of the body. Fading of scars depends on certain factors that include size, type of scar, depth of the scar and other personal factors as age and genetics etc.

What Are The Types Of Scars?

Types of scar include:

  • Hypertrophic scar
  • Atrophic scar
  • Rolling scar (after acne heals)
  • Ice pick scars (after acne heals)
  • Keloid

Scars in addition may or may not be hyper or hypo pigmented.They may have associated broken capillaries in them, and may or may not be associated with deformity or disfigurement of the surrounding tissue, etc.

What Is The Laser Scar Reduction Treatment Procedure?

Treatment  depends on type of scar.

  1. Hypertrophic scars can be treated with steroid injections. Once they flatten, their surface can be lasered to reduce the visibility and try to bring them as close to normal appearaing skin as possible.
  2. Keloids can also be treated with s t e r o i d injections, b o t u l i n u m toxin injections, cryotherapy etc. followed by laser resurfacing if possible.However, keloids may also aggravate post laser and one has to judge if lasering for keloids would be appropriate in any particular patient.
  3. Atrophic scars also known as depressed scars commonly found after acne heals, usually improve significantly with  laser skin resurfacing with or without injectable fillers.
  4. Ice pick scars, post acne are very deep and may require a procedure called subscision to break the under scar fibrous bands, before they can be lasered away.
  5. Scars like stretch marks, can be improved by a combination of microdermabrasion, radiofrequency and fractional co2 laser treatment in some cases where the stretch marks are reddish and recently developed. Results in later stages are far from satisfactory.
  6. Occasionally for non linear surgical/traumatic scars, surgical correction/realignment  may be advised before starting the laser treatment.
  • Non-surgical laser scar treatments include fractional lasers, most preferred being the ablative fractional carbon dioxide laser, that deliver light in an array of high precision micro beams. These micro beams create narrow, deep columns of tissue coagulation, penetrating well below the epidermis and into the dermis, while sparing the tissue surrounding the columns from damage.The heat stimulates new collagen formation and gradual resurfacing of the scars happens over time.
  • This is an outpatient procedure and usually only topical anaesthesia is  required.  There could be some pricking sensation during treatment with the laser.Some burning sensation post laser for a day is usual, there could be mild redness, swelling post laser for a few days followed by darkening and peeling off of the skin in the treated area. Sun protection is mandatory during therapy.
    Since the procedure is non-invasive, the patient will be discharged immediately after the treatment and can go back to normal life with no hospitalization required.
  • Depending on the severity, number of treatments may vary. from 4-10 sessions  with 4 weeks interval in between two sessions.
    What  Happens After The Treatment?
  • There could be some pricking sensation during treatment with the laser, though it is done under topical anesthesia application.

However, follow up treatments are usually necessary at 1-2 month intervals along with topical anti scar medications prescribed specially from the clinic.
Scars continue to improve over time even after the required number of sessions are over.
