The short answer is no. Though there are a lot of products marketed to pregnant women who are willing to spend a lot of money to prevent stretch marks, none of them have good scientific data showing they work. Some products cite their own small studies, but they are usually poorly done or so small that it cannot be considered good evidence. Companies like to exploit new moms, so be leery. We don’t want that for you. Save your money. If your belly is dry and it feels good to use a nice lotion or other skincare product, go for it! But know that it will not prevent stretch marks. We promise the second we see something come out that is effective and has good data behind it, we’ll be the first to tell everyone.
