In this way, the laser’s optical fibres perform a very precise abrasion without causing burns or damaging the surrounding tissue. The coagulation of the tissue breaks down damaged cells while stimulating the growth of healthy ones and the production of new collagen. Sometimes, as in the case of a hypertrophic scar, a preparatory treatment is necessary. However, even long-standing scars can be At present, the most effective method for treating scars is the fractional non-ablative laser. The name of this kind of laser comes from its feature of emitting the light beams in many close shots.treated, achieving good results.
