Fractional Laser Treatment for Scar Improvement - Plastic Surgery

Fractional laser


Hello, Doctor.
I previously underwent scar revision surgery on my face due to a burn injury.
If I want to undergo fractional laser treatment to make the scar smoother, should I wait until the scar has turned white and matured before proceeding? The scar is currently 7 months old, but it is still somewhat red in the middle.
I'm concerned that if I undergo the treatment now, it might irritate the wound and cause it to become raised.
Additionally, I've heard that the longer a scar has been present, the longer the laser treatment will take.
Is that true? Thank you for your response!

Laser treatment for scars primarily focuses on pigment reduction.
There are many variables involved in treating facial scars with laser therapy, including tissue irregularities and fibrosis.
Regular follow-up is reasonable, but frequent treatments may actually be harmful.

Fractional laser treatment is a popular and effective method for improving the appearance of scars, including those resulting from burns or surgical procedures. It utilizes a laser to create microscopic wounds in the skin, which stimulates the body’s natural healing processes and promotes collagen production. This can lead to smoother, more even skin texture and a reduction in the visibility of scars.

In your case, since you have undergone scar revision surgery and are considering fractional laser treatment for your facial scars, it is essential to understand a few key points regarding the timing and effectiveness of the treatment.

First, it is generally recommended to wait until the scar has matured before undergoing laser treatment. Scar maturation can take anywhere from several months to a couple of years, depending on various factors, including the type of scar and individual healing processes. In your situation, since your scar is already 7 months old and still appears red, it may not yet be fully matured. The redness indicates that the scar is still in the healing phase, and treating it with laser therapy at this stage could potentially lead to complications, such as increased irritation or even hypertrophic scarring (where the scar becomes raised).

Typically, scars will transition from red to a lighter color as they mature. This process can take time, and patience is crucial. Once the scar has faded to a more neutral tone and has become less raised or irregular, it is usually a better time to consider fractional laser treatment. This allows the laser to work more effectively on the scar tissue without the risk of exacerbating inflammation or irritation.

Regarding your concern about the duration of treatment, it is true that older scars may require more sessions for optimal results. This is because the longer a scar has been present, the more established the scar tissue becomes, making it more challenging to treat. However, the specific number of sessions needed can vary widely based on individual circumstances, including the type and severity of the scar, skin type, and overall health.

It is also important to consult with a qualified dermatologist or plastic surgeon who specializes in laser treatments. They can assess your scar and provide personalized recommendations based on your skin type, the characteristics of the scar, and your overall treatment goals. They may suggest a treatment plan that includes a series of fractional laser sessions spaced out over time to allow for adequate healing between treatments.

In summary, while fractional laser treatment can be an effective option for improving the appearance of scars, it is crucial to wait until the scar has matured and to seek professional advice for the best approach. This will help ensure that you achieve the desired results while minimizing the risk of complications. Always prioritize your skin's health and healing process, and don't hesitate to reach out to your healthcare provider for guidance.
