Have you heard of scar massaging? When you're 6-8 weeks postpartum, if your incision is healed, it's a good time to start massaging the scar. This will help scar tissue form in the right direction which will keep it from attaching to surrounding fascia and connective tissues. This is especially helpful if you have a tendency toward excessive scarring (like keloid or hypertrophic scar formations).
It's safe to use aloe vera gel or vitamin E oil when you're massaging the scar and surrounding areas. To begin, gently press on the area surrounding the incision site and move your fingers in a circular pattern. Don't press down too hard – it should not be uncomfortable. After the circular motions, continue massaging the area surrounding your scar using vertical and horizontal movements. This will help make the area less tender and more mobile, and as you feel comfortable, you can begin massaging the scar directly.
