Laser Scar revision

Scars are the result of the cutaneous wound healing process that leads to fibrosis and altered skin morphology. The skin injury could be due to accidental trauma, burn, surgery, skin disorders such as acne, chicken pox or due to rapid growth of body resulting in stretch marks. A scar is a mark left on the skin after an injury or wound has healed.

Scars (external link) can have significant cosmetic, physical, and psychological impacts on patients, prompting many to seek treatment.

Types of scars

A scar can be a fine line or a pitted hole on the skin, or an abnormal overgrowth of tissue.

Normal fine-line scars or Linear Scars are common following surgery or linear cuts made over the forearm.

A minor wound like a cut will usually heal to leave a red, raised line, which will gradually get paler and flatten with time; which usually takes two years and appear as visible mark or line; in darker skin leave a brown or white mark.

Keloid scars

A keloid scar is an overgrowth of tissue that happens when too much collagen is produced at the site of a wound. Keliod scars are larger than a hypertrophic scar  and extend beyond the edges of an original wound or trauma. Keloids can occur anywhere on the body, but they occur more commonly where there is little underlying fatty tissue such as the face (low part), neck, ears, chest, shoulders, and upper arm.

Keloid scars  are raised above the skin and can be pink, red, the same color or darker than surrounding skin. They’re often itchy or painful, and can restrict movement if they’re nearer to a joint

Hypertrophic scars

Like keloid scars, hypertrophic scars are the result of excess collagen being produced at the site of a wound.

Unlike keloid scars, hypertrophic scars do not extend beyond the boundary of the original wound. They may continue to thicken for up to 6 months before gradually improving over a few years.

Atophic scars or sunken scarring

These are caused when underlying structures supporting the skin, such as fat or muscle and collagen; are lost and appear as pitted scars. Atrophic scars are often associated with acne, chickenpox, bacterial infection, and insect or spider bites. 

Scar contractures

Contractures are scars that restrict movement due to skin and underlying tissue (muscle and nerves) that pull together during healing. They are seen in patients who have burns and a large amount of tissue loss. Contractures usually form where a wound crosses a joint, restricting movement of the joint and called contractures.   

Treatment of scars

A number of treatments available to treat scar; most of them can be made to merge with surrounding skin to an extent of 30% to 95%. Though there are plenty of options to treat scars such as silicone gels or sheets, steroids, cryotherapy , dermal fillers, micro-needling and surgery, but laser treatment has its own stand.

 Thanks to advanced laser technologies which have enhance ability to improve the appearance, symptoms, texture, and pliability of all scar types.

Laser scar revision utilizes photothermal energy to target intra- and extra-cellular structures within scar tissue to stimulate eventual remodeling of dermal collagen and elastin. These lasers are also used to target blood vessels in the scar tissue and reduce redness or they can also penetrate the skin’s surface to stimulate the production of new skin cells. Most recently, fractional photothermolysis with ablative and non-ablative fractionated lasers have found use as effective treatments for scars.

Advantages of Laser Scar Revision

The procedure requires a topical anesthetic to numb the skin.

  • It is an outpatient procedure.
  • Mild side effects such as pain, swelling, redness, and temporary oozing which usually disappear in a couple of days.
  • There’s no long downtime with this procedure and usually healing occurs in 3 to 10 days.
  • The results are long-lasting, though it may take weeks or months before you notice a difference.

Types of lasers used for scar revision

Ablative or laser resurfacing

Carbon dioxide (CO2)) and erbium:YAG (Er:YAG): Resurfacing lasers removes the outer layer of skin and eliminates skin cells that have been damaged at the surface level and very effective in the treatment of atrophic acne scars. Carbon dioxide (CO2) laser  for deeper scars or an erbium laser for surface scars. Fractionated ablative lasers is an advancement in both these CO2 and Erbium, the laser penetrates a deeper layer of the skin’s surface to remove dark pigmented cells and stimulates collagen production and makes scar less noticeable. These lasers are effective in surgical or traumatic scars and atrophic acne scars

Ablative or laser resurfacing

The Infrared heat lasers penetrate the inner layer of the skin. This also stimulates collagen production and cell renewal to replace damaged skin cells.

Non-ablative fractional lasers such as Erbium glass most commonly used is for atrophic scars & non-ablative non-fractional lasers such as the pulsed dye laser and Nd:YAG 1064  or IPL have been shown to be effective in the treatment of hypertrophic or keliodal scars and erythematous scars. Non-ablative, non fractional lasers primarily target hemoglobin, and when combined with surface cooling allow thermal remodeling of the dermis while sparing the epidermis which is a vascular.

Pre and post laser precautions for scar revision

Before

DO

  • Avoid UV exposure 7 to 15d days prior to your treatment.
  • Avoid chemical peels and exfoliating skin products (retinol or glycolic acid), seven to ten days prior to laser treatment.
  • Stop smoking at least two weeks before your treatment.

DON’T

  • Do not forget to use broad spectrum sun screen SPF30+ for 7 – 10 days, if you step outdoor work.
  • Don’t take aspirin, supplements, or medications that can slow the healing process.
  • Do not hide the history of peri-oral or genital herpes simplex virus, as your physician may recommend prophylactic antiviral therapy.

After

DO

  • Use regular sunscreen (only 24 hours after treatment) for 4 wks to 6wks.
  • Apply a cold pack or ice cube to the area to reduce swelling
  • Keep your skin clean and moisturised (especially the treated areas). Use aloe-vera gel moisturizer, as it keeps the area moist and helps in healing by hydrating the skin. As after fractional scar treatment, the skin’s integrity is usually compromised, making it vulnerable to bacteria and dirt.
  • Do avoid makeup for at least 24 hours following the laser scar treatment. After 3 days light makeup may be applied to but it is safer to only start your full routine after all the scabs have healed.
  • Take over-the-counter pain medication when needed
  • Avoid smoking for at least 2 weeks post-procedure as it significantly delays healing and increases the risk of complications.

 

DONT

  • Do not exposure to sun or UV rays, so step out in sun after applying broad-spectrum sunscreen>30SPF. This is to reduce the risk of post-treatment hyper-pigmentation.
  • Do not rub, scratch or pick the area after receiving laser treatment as it requires time to heal so, be delicate.
  • Do not let the skin feel dry or tight. Always keep it moisturized
  • Use any personal skin care products for 2wks after the procedure that cause burning or discomfort.
  • Do not use abrasive skin cleansers and scrub or shave the area. Always gently pat the skin dry.
  • Don’t forget to continue medication prescribed by doctor
  • Don’t hesitate to call for any questions regarding your condition, it is best to call the during regular office hours.
