Cesarean section scar, i.e. lower abdominal incision scar after cesarean section, can be improved by medication, physical therapy, surgical treatment and other measures to improve its poor appearance. 1. Medication: Early scarring can be treated with topical medication such as cumeneoside ointment and mucopolysaccharide polysulfate ointment, which can inhibit scar proliferation and improve the appearance of scar in the later stage of scarring. 2. Physical therapy: the photothermal effect of carbon dioxide laser can start the process of skin damage repair, stimulate the regeneration and rearrangement of local collagen tissue, and promote the recovery of cells to improve the color of keloid scar, which has a clearer effect on improving the appearance of keloid scars, but it needs several times of treatment. 3. Surgery: If the scar proliferation is obvious and no obvious improvement is seen after the above treatment, the scar tissue can be removed through surgery, and then reduced tension suture again. If you are willing to treat cesarean section scar, it is recommended that you go to a regular medical institution, follow the specialist’s instructions to standardize the treatment, and avoid abusing medicines and health care products, which may cause adverse reactions.
