I have been using this product for quite some time now but am yet to see any difference to the appearance of the marks. The smell is quite strong and the oil takes a while to soak in so is best to apply of an evening before bed as to not get on your clothes. The bottle is quite simple but for some reason it seems to always leak with the twist off lid.
I would not recommend this product as after using it for 6+ months I have not seen any noticeable difference to the appearance of stretch marks.
Like everyone, I initially used Bio-Oil in the hopes of preventing stretch marks. I can't say it *absolutely* didn't work - I didn't get stretch marks around my belly button, which is mostly where I applied it - but I did get them very low on my abdomen and round my hips, where I hadn't applied it as religiously. Legitimate correlation or just the way I carried? No idea.
But! Several months ago I started using it on my legs and elbows in the vain hope it'd help my psoriasis. It didn't even claim to help psoriasis, but nothing else was working and I figured it was worth a shot.
Well, it took a while, but my plaques are now completely gone. To be honest, it might have been the strict moisturising regimen as much as the actual content of the moisturiser... but it worked! Smooth elbows for the first time in years.
I've also noticed that a dab on my face helps heal acne scars quickly, as well as being a nice light moisturiser.
I know this stuff's controversial, but I like it... for certain purposes. And as much as it costs, it's cheaper than rosehip oil.
