Bio Oil is hugely popular amongst pregnant women, new mothers and people with scars to the point that it is ubiquitous. But does it really work? We tried it to find out.

Our tester put it on an existing stretch mark twice a day as instructed. She did notice a visible improvement after a few months. The stretch mark was very purple when she started and it was fading more as time went on. Of course stretchmarks tend to fade anyway but it take years for them to go from the red/purple angry scars to the silvery/white tiger stripes. Bio Oil does speed the process along. Boots.com frequently do a buy two get one three deal so you can also save yourself some pennies.

Have you used Bio Oil? Did it work for you? Would you recommend it to a friend?
