Hello, laser scar removal by caesarean section is effective. When laser is used to remove the scar of caesarean section, firstly, drugs are injected locally to inhibit the proliferation of reticular fibers, and at the same time, the dye pulse laser with a specific wavelength is combined to irradiate the hyperplastic blood vessels, so that the hyperplastic scar is released, and the scar is gradually flattened and thinned, and it is restored to a thin line mark, which can effectively improve the scar of caesarean section.
