For a variety of reasons, many moms today choose to have a cesarean section, which inevitably leaves them with a postpartum scar. Postpartum scars are generally white or off-white, smooth and hard. Two to three weeks after the surgical incision scars, the scars begin to proliferate, when the local redness, purple, hardening, and protruding from the surface of the skin. Postpartum scars affect the beauty, so it adds a lot of trouble to the mothers. So, for postpartum scar repair has become a hot topic of concern for mothers, all kinds of questions also arise, in order to solve the doubts of mothers, I deliberately visited the Air Force General Hospital Laser Plastic Surgery and Aesthetics Center of the experts, the following two common questions about postpartum scar repair, experts for specific answers. According to expert explanation, due to the surgical incision scarring two to three weeks later, the scar began to proliferate, at this time the local redness, purple, hardening, and protruding from the surface of the skin. It lasts about three months to half a year or so, the fibrous tissue proliferation gradually stops, and the scar gradually flattens and softens, and the color becomes dark brown, at which time the scar will appear painful and itchy. Especially when there is a lot of sweating or weather changes, the scars are so itchy that you have to scratch and see blood before you can give up. Therefore, in the scar patients have pain is good to endure, itching is difficult to say. Therefore, postpartum scar repair is very necessary. Postpartum scars can be repaired by laser or surgery. When using the laser method for postpartum scar repair, first of all, the local injection of drugs to inhibit the proliferation of reticular fibers, combined with a specific wavelength of the dye pulsed laser irradiation, closed hyperplasia of blood vessels, which can achieve the purpose of loosening hyperplasia of scars, so that the scars gradually flatten and thin, and finally restored to seem like a thin line trace. As a precautionary measure, experts suggest that pulsed laser irradiation 1-2 times 2 weeks-4 weeks after cesarean section and other surgeries can largely avoid the appearance of earthworm-like scars. When using surgical methods to repair postpartum scars, for unsightly scars or hypertrophic scar tissue caused by infection or foreign bodies, the scar can be excised and re-sutured. In the case of a scar with one straight incision, the incision can be re-designed in different directions and at different angles on this straight line of scars to disperse the tension of the straight line of wounds, blurring the focus of vision, and to achieve the purpose of beautifying the scars. For ugly scars caused by protruding belly, the best way is to do liposuction or abdominoplasty first, to tighten the fascia of the abdominal muscles first to restore the tautness, and then remove the excess skin, and then re-suture the incision under the state of minimal tension, the ugly scars as well as the body shape of the postpartum period can be drastically improved at the same time.
