I recently purchased Bio Oil after watching few videos of it uses. And I am quite satisfied with the results. The oil when applied to face or hands will make the skin very mosturised and shiny ??. I am using it dince few weeks only so can't say how it works on any marks etc. But I somehow have gained confidence on it. I even gifted one to my mother and told to use it regularly. And yes may be I have not seen much result in reduction of marks because I became irregular in its use. So I think for best results one must use the product on regular basis.
