hi H&K... i've tried and tested BIO OIL. I have various scars on my arms & hands due to burns and the Bio Oil certainly has reduced the redness of them, they are quite faint and not so prominant now. It cost about �8-�9 for a smallish bottle but you do only need a very small quantity to rub in each time, it took me about 10-14 days to start to notice a considerable different in the redness of scars (which i'd had for a good few years). Make sure you apply according to the instruction on the bottle and be a little patient, its not a miracle worker. I would recommend it. But like warpig said it may depend on the type of scar you have, as to how good this product is. Good luck.
