Has anyone tried Maelys B- Flat for stretch marks or loose skin??

Hi mama’s after gaining way too much weight while pregnant I now have a bunch of stretch marks on my stomach/thighs/ back of my legs that make me super insecure. I was wondering if anyone here has tried the B-flat cream by Maelys and if it worked. I’m trying to do anything to decrease my stretch marks but can’t afford laser removal at the moment. I exfoliate 2-3 times a week and have just started to use a Derma roller once every 4-5 weeks. Thank you for any advice!! 💕
