Scar proliferation can be prevented after cesarean section by proper exercise, lap-banding and application of scar removing drugs (such as vitamin E). 1. Appropriate exercise: Exercise can accelerate local blood circulation and promote the healing of wounds as soon as possible after cesarean section, thus reducing scars and preventing scar proliferation. 2. Lap-banding: Lap-banding can reduce the tension in the abdomen and prevent the formation of hyperplastic scars. 3. Application of scar removing drugs: after the wound heals, you can apply topical vitamin C, vitamin E and other drugs to promote the scar to become smaller and flatter, thus preventing hyperplastic scars. If you want to better prevent the formation of scars, it is recommended that you consult a doctor in time after delivery to observe the recovery of the wound, use medication under the guidance of the doctor, and avoid unauthorized use of medication.
