What the gurus are saying

Dermatologists and skincare experts widely dismiss Bio-Oil as ineffective and overpriced. The core issue: it's mostly mineral oil with heavy fragrance, and there's no clinical evidence that topical application prevents or removes stretch marks, which form deep in the skin from rapid expansion. While mineral oil can lubricate and temporarily hydrate scars, the same benefit costs far less with plain mineral oil and avoids the irritation risk from 14 fragrance ingredients. The repeated claim that gurus see from users is confusing correlation with causation, people who didn't get stretch marks likely have genetics to thank, not the product.

"Things like Bio-Oil, shea butter, cocoa butter, these really prey on a person's insecurity about developing stretch marks, but they have never been shown to actually be effective in preventing them."

Skincare Trends That Need to STOP | Dr. Sam Ellis
"Any time I talk about stretch marks I will always get comments that are like well I used Bio Oil on my belly during pregnancy and I didn't have a single stretch mark that is so wonderful but that's not the Bio Oil that is just what your body is naturally doing."

"When I looked into it, it was loaded with fragrance. It contained vitamin A and it didn't contain any collagen stimulating actives."

TREAT Stretchmarks during Pregnancy Doctor V explains
"I actually made a video on Bio Oil years ago. Bio Oil is the number one product right now for stretch marks. And when I made the video, I was shocked to learn that it contained vitamin A, retinyl palmitate. It's a blanket no when it comes to vitamin A during pregnancy, just like it's a blanket no on using Botox during pregnancy. When I looked into it, it was loaded with fragrance. It contained vitamin A and it didn't contain any collagen stimulating actives."

"Retinol palmitate, which is found for example in BIO Oil, is the weakest form of vitamin A."

"Bio oil, anyone who says that this is helpful, they're getting essentially the benefits of using mineral oil to lubricate the scar, cut down on frictional forces, but they're adding in a steeper price point, $38.49 mind you, plus fragrance which again can be irritating, not always but for some people it can be irritating. Fragrance and essential oils ultimately will worsen the appearance of the scar, so this is not something I recommend. People who use it and claim that it helped their scars, just know it worked by lubricating the skin surface. You can get that same effect for half the price without the risk of irritation from fragrance just by using mineral oil or any of the skin protectants."

*NEW* SKINCARE AT THE DRUGSTORE | Dermatologist
"I don't understand the hype. It's basically mineral oil with fragrance and not much else. Mineral oil certainly can lubricate scars and hydrate scars and ultimately may cut down on frictional forces that lead to scar thickening, but that's about it, and you don't need special Bio-Oil to do that. You could do that really with any body oil. The other thing about this is that it claims to help improve the appearance of stretch marks, that seems unlikely. That's a very lofty claim. Stretch marks originate down in deeper parts of the skin related to quick expansion of the skin with changes in weight or if someone's on an oral or topical steroid that can thin the skin and cause stretch marks. So that's a very lofty claim."

"Bio-Oil, in my opinion, the biggest scam ever, probably the biggest blatant lie in the skincare industry that we all fell for. Bio-Oil has always advertised themselves as a blend of oils that helps remove stretch marks, which it kind of is potentially maybe. When you look at the ingredients, it's essentially just a cocktail of oils and 14 different fragrances. This is really overboard and really potentially irritating for those with easily irritated skin. The fragrances are all listed individually because they have to be, because they are some of the most known irritants when it comes to skincare."
