I bought bio oil for stretch marks mainly. After giving birth to my daughter, I had a few stretch marks on my stomach, but I found that the best ‘cure’ for stretch marks, in all honesty, is just time. Over time, they’ve faded naturally and are now no longer a major issue for me. But I know for a fact that bio oil had nothing to do with that as I gave up on it after giving it a good trial. Time was the only thing that helped me with stretch marks. So I’d give bio oil a mark of one kiss out of five for helping me with that particular skin issue.. Ditto with uneven skin tone and scars. To be fair, I don’t have many scars and my skin tone is pretty even overall, but still ... for any minor problem patches, I found bio oil did absolutely zilch for me in those areas.
One area I DO think this oil is useful in is with extremely dry or ‘dehydrated skin’, which is one of the other claims it makes on the packaging. It does moisturise well and soften the skin. It feels pretty greasy when you apply it and it does take a while to absorb, but it’s very hydrating. So it’s for that reason I’d personally give this oil two kisses out of five. Because it works well as a moisturiser. But I agree with one of the other reviewer’s comments below that it’s just a ‘glorified moisturiser’ because any other really good-quality, reputable moisturiser can also help with dry skin, you don’t necessarily need to rush out and buy this oil if you have dehydrated skin. In fact, a fair few other oils can also help hydrate the skin - not just bio oil.
