The product: Belli Skin Care Stretchmark Minimizing Cream ($49)
Why people like it: Users rave about this cream's ability to minimize already-existing markings. "I've used so many skin creams, lotions, oils, and many expensive ones for pregnancy and stretch marks. This is the only product that has actually worked and has the best scent of all I've tried, too. My stretch marks are less noticeable after my second pregnancy than after my first thanks to this cream. I started noticing a difference within a week."
