I don't believe that this is something that can reliably be done. If you need to get something done after you heal, then your options include injections ( it the scar is thick or keloidal), or topical steroids if it is very itchy. One factor will be how quickly you get back to your pre-pregnancy weight. As a Mother of twins, you may do this more quickly since you will be very busy! Good luck to you all!
Scars vary in severity after c section surgery. Our office recommends early pulsed dye laser therapy and topical cream application with Plato's Scar Serum twice daily.
