Depending on the location and age, etc. BF&C capsules or tea would be suggested daily as well as a small portion of salve rubbed directly onto the scar.
If you wnat faster results and it is an area that can take some heat, the use of a cayenne type salve also would be used. I make the Amish salve with 1/2 cayenne for the spine and also use a pure cayenne oil to put direct on a spot that needs healing. You use 1/2 of 1 drop, it burns or has that cayenne burn feeling and your blood comes to that point to carry away the cayenne, ideally it takes away the scar also. This does take time and your body needs to have good clean blood.
