Sophie, it has nothing to do with natural=healthy and artificial=evil. There’s just very, very, very little Tretinoin in rosehip oil. It is the dose that makes the poison.

Tretinoin and other forms of Vitamin A are not recommended during pregnancy because high doses of Tretinoin cause birth defects in mice. We’re not mice, so we have no way of knowing if this applies to humans. But we can’t do these studies on humans either (for obvious reasons!) so doctors recommend you stay away as a precaution.

I know women who used rosehip oil and small concentrations of retinol during pregnancy and their babies were born completely healthy and fine. But again, without a study that says “this amount is safe and this amount isn’t” (which, again, will never happen), doctors will recommend to stay away from everything for fear of law suits.

Elisa, I’ve written a post about what ingredients to avoid during pregnancy. You can find it here: https://www.beautifulwithbrains.com/skincare-ingredients-avoid-pregnancy/

In a nutshell, avoid any form of vitamin A and focus on antioxidants, like vitamin C.

Mei, it’s still a salicylate, so I’d avoid it. Just to be on the safe side.
