I have bio-oil - it's a little bottle of oil and it cost me about £9 which i thouht was expensive but i've had it for about 6 months now and there's only a really tiny bit out of the bottle - i haven''t used it everyday but i used it quite alot. You can get some more information at
www.bio-oil.info
I bought it as i got a burn on my arm from a tray just out of the oven and it stretched right across my arm it was like 8-10cm and now it's about 5cm and the colour is faded alot. It's pretty good.
I hope this helps some.
Well done for the positive attitude towards SI.
