Gonna start by saying I have very sensitive and blemish/discoloration prone skin.

I have stretch marks on the inside of my thighs from gaining about 10lbs recovering from an eating disorder as a teen.

I suffered from cystic acne from 20-22 and occasionally now (23).

So when I learned I was pregnant, I knew my belly was going to be wrecked with stretch marks.

As long as your baby is healthy it’s worth it, but who doesn’t want to avoid them?

So I got online and researched and like lots of things when your pregnant, I forgot about it.

Around 5 months when I finally started to show, I said screw it and bought a bottle of BioOil at the grocery.

I kept telling myself “I’ll get one of those expensive special belly lotions/oils if this starts to not work” but it just kept working!

Here I am at 37 weeks, I’ve gone through about 24oz of BioOil and nothing else, and I am yet to have one stretch mark!

Time will tell and I’ll update this after my little boy gets here, but if anyone is looking for something easy to use that helps prevent stretch marks, try this first!

The texture is great, it soaks into your skin instead of just sitting on top and it really works!

(PS I also use it on my breasts, so far it has helped prevent sagging and marks there too, even through the crazy growth).

I really hope I didn’t jinx myself but I just had to share with anyone else out there looking for a low maintenance way to avoid stretch marks.

Twice a day, takes 2 minutes, and it works! I’ll be using this postpartum and into the future as I age.

Some customers saw results, but not what they expected.

I bought bio oil for a two month old surgery scar (vertical incision, bellybutton to pelvic bone).

Apply it on my scar mornings and nights for almost two months (only missed one night).

It is a keloide scar so it was deep red at first, after three days of applying bio oil it turned like deep pink….. An improvement and I was happy so continue using it….but no luck for me, i have not seen an improvement and I decided to buy a different product.

Bought Mederma, three times applying it to my scar and today I noticed that it has shrink like 20%, even my husband noticed.

I gave it three stars because I also applied bio oil to my face every night and it helped with my skin tone.

I will keep applying it every night.

I also applied it (mornings and nights) on some old stretch marks and I can see an improvement, probably I am the only one to see it but I will keep applying it.

I guess it depends on your skin type and you need to try what works best for you….. Good luck!

Some customers claimed dissatisfaction.

Don’t use it on your face especially if you’re acne prone.

Bought it to treat acne scars and it ended up breaking me out horribly and just making the situation worse.

I looked it up on per my dermatologists recommendation and it has ingredients in it that are acne causing as well as irritating.

It would maybe be tine on the rest of your body but I don’t really need it.

Going to give it to someone.
