Scars cannot be completely removed with lasers. No scar can be completely removed by any treatment, but only for the purpose of treating the scar to improve its appearance as much as possible.
Laser scar removal refers to the use of specific wavelengths of laser light generated instantly by the photothermal effect, selectively destroy the blood supply of the scar site and scar tissue, occlusion of scar local capillaries, gasification cutting scar tissue, promote scar collagen rearrangement and other mechanisms to improve the appearance of the scar.
Generally, after several laser treatments, the appearance of the scar can be significantly improved, but still can not completely remove the scar. Currently, lasers used in the treatment of scarring mainly include dye laser, carbon dioxide fractional laser, erbium laser and so on.
It is recommended that patients who are willing to be treated should go to regular hospitals and under the operation of professional doctors.
