it is called "Heal Gel" and is sold here .
I have been using it on my tummy tuck scar and it has made a rapid difference. Within 2 days of use, it has gone from red and raised (sounds vile but is actually quite normal at 6 weeks post-op) to barely noticeable. Have also used on a lumpectomy breast scar which is now 11 months old and it has vastly improved too.
Just thought I would mention as there have been lots of Bio Oil threads recently. This is expensive but you use just a little each time.
