I brought this to help with dry skin, scaring as well as stretch marks.
When I used it I really disliked how long it would take to soak into my skin. I would put on my legs if wearing clothes that wouldn't go near the skin. So I tried mixing with moisturizer hoping that would help. It didn't :(
I heard it would be good for hair, so I tried putting mid way down to ends. Yes it did soften slightly at the ends.
If I had some on my hands and put on my face, my skin loathed it. Itchy and break out in a kind of pimple rash.
I'm sure it would be great for some people but not for me sorry
So I brought this not for my stretch marks, but as a moisterizer in winter for my dry skin. I believe that if you're going to get stretch marks, you're going to get them and no "miracle" cream is going to prevent that.
Bio oil is great for dry skin. I only use it in winter as it's quite oily and in winter my skin gets quite dry. Using this stuff my skin is never dry! I only use it at night and by the morning, my skin is soft and moisterized and all the oil has been absorbed into my skin. I love it! I've been using it for the past 3 years (only in winter) and the condition of my skin has never been better. My skin tone is also nice and even. Overall, I love this product.
Tips: I don't use this product in any kind of warm weather as it is quite oily and just does not feel nice on sweaty skin!
