The BF&C internally, maybe 3 capsules daily for 9+ months along with a very thin layer of B&W rubbed daily on the scar, would be my best advice. It depends on what kind of scar, how deep, etc. Do not expect a miracle, it will take along time. My scars on my body have faded to the point I have to look close to see them and a very bad burn scar at age 7 is gone and bad scars from about age 7-10 are 98% gone. I at least learned to get no new scars.
