WHICH FRACTIONAL LASER IS BETTER FOR TREATING SCARS?
A scar is an imprint that remains after wounds heal. Which laser to choose?
In the past, treatment was only aimed at treating rough scars, such as hypertrophic and post-burn scars. However, scars from small wounds can also be a cause of stress for patients. When a tyrectomy is performed, a postoperative scar remains on the front of the neck in women who make up the majority of patients, which can be considered a cosmetic defect. Active prevention gives better cosmetic results and requires fewer procedures and, consequently, less expenses than scar excision surgery.
There are many treatment options available in the literature, but there is still no General consensus on the optimal treatment for scars. Recently, there has been an emphasis on “laser scar prevention” using different types of fractional ablative and non-ablative lasers.
Ablative fractional laser-during the procedure, the integrity of the skin is violated (microchannels are formed deep into the skin).
Non-ablative fractional laser-the procedure takes place without violating the integrity of the skin (leaving micro-columns of “baked” tissues deep into the skin).
Ablative fractional laser is more effective than non-ablative laser in the treatment of scars
A comparative clinical study of non-ablative and ablative fractional laser for the treatment of postoperative scars in patients with skin types III-IV according to Fitzpatrick was conducted. Patients were treated with one half of the scar with a non-ablative fractional laser, and the other half with an ablative fractional laser. The results showed that ablative lasers are much more effective at correcting scars than non-ablative ones.

When to treat a scar?
There is an opinion that postoperative scars should be treated only after they “Mature”, that is, at the later stages, when scar tissue has formed. Other experts believe that it is better to start laser treatment of scars as early as possible. In this study, treatment of postoperative scars with fractional laser was started immediately after removing the stitches from the wound, that is, at an early stage.
