No doubt is is an amazing moisturizer. It didnt do much for my pregnancy stretch marks though. My stretch marks have faded but they naturally fade. I know bio oil really didnt do anything because I applied a couple of the large sized bottles on my stomach as recommended. I did forget about the ones I had on my inner thighs from pregnancy and when comparing both stretch marks on my thighs to my stomach after using bio oil, they had both equally faded. The key to stretch marks is good genes first off. Keeping skin hydrated with lots of water, maybe take some vitamin e and moisturizing will help. Which bio oil is a good moisturizer. But for $20 a bottle its too pricey for me.
I think its hard to tell if the product actually works or not in terms of stretch marks.. I think many people dont realize, that yes.. after several months your stretch marks WILL not look the same... they all lighten up and turn white. The only way you can tell if its working or not is not using the product on other stretch marks that erupted at the same time.. and then doing a comparison.
