I like so many others tried Bio oil when I was pregnant. I found it stung, and left a very greasy residue.. having paid a lot for a big bottle, I put it in the draw until my son was 5 months old and tried it again. It dried my skin out like crazy, and generally did the opposite of anything you'd want in a moisturizing product. I kept using it for 2 weeks to give it any opportunity to work, and in the end my skin was a dried out flaking mess. I switched from bio oil to plain old olive oil out of the pantry and found it amazing in comparison.. I can only assume that the chemical mineral oil base in Bio oil is what caused the issues. Disappointed in the results, and also the marketing - its advertised to give the impression of a natural gentle product, which it isn't.
If I could give it less than 1/5 I would.
I am a plus size girl, and from many health reasons my size isn't small, and as a result I got strech marks ALL OVER. When I first herd about Bio-Oil I was like, hmmm I am not entirely sure if this will work. Then I trailed it out for about a month. I don't know how but my strech marks are worse! I haven't gained any weight but they have mutiplied, and since using Bio-Oil it has caused a huge irriation on my body rashes every where! I am horrified. It sounds great in theory, but it is in the bin now!
