6 experts · Strong agreementWhat the gurus are saying
Fragrance keeps coming up, and experts warn it can irritate skin, so anyone with easily irritated skin may want to be careful. Most of the gurus who weighed in doubt the stretch mark claims, and the vitamin A in it gets a firm no during pregnancy. Gentler takes call it enjoyable and unlikely to cause side effects, with the massage possibly doing more than the oil, though no one can promise results.

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
