Stretch marks after birth?

So my whole pregnancy I always drank plenty of water and always put bio oil and some other oil to not get stretch marks and I didn’t but after I had the baby I started to notice that I did have them and then my tummy was really dark but I snatched up pretty quick just wearing a tight belly band aka faja because you know Mexican moms have all these weird things to do after birth and my mom also gave me this cream she got from Mexico which worked wonders I swear by it! But I’m pregnant again so we’ll see how I do this time lol

What did you ladies do to snatch your tummies or tighten your lose tummy skin or get rid of stretch marks that you think worked wonders!?
