Yes Bio Oil does help lighten up your skin.
The use of Bio Oil on your skin is a good way to see lightened skin.
To use Bio Oil to lighten up your skin take the Bio Oil and massage it into your skin everyday or at least every few days until you see lighter looking skin.
For me it took 30 days to start seeing lighter skin from the use of Bio Oil on my skin.
I massaged the Bio Oil into my skin daily for those 30 days and continued to do so for at least a few months afterwards.
Then after about 60 days of using the Bio Oil on my skin I saw significant results.
Then to keep your skin lightened up continue to use the Bio Oil on your skin at least once per week.
You can also use Aloe Vera Gel, Cucumbers, Lemon, Honey and Paypaya to lighten the skin naturally.
