stretch marks

ok so my whole pregnancy I only had a couple small stretch marks on my hips. towards the end I got a few on my belly and once I had my daughter, I got a lot more on my belly and they're kinda dark. I'm very aware once you get stretch marks, they really don't go away (I had them dark on my inner thighs, but they lightened up a lot now they're white) but does anyone have advice on how to soften them up, make them lighter, anything? I've read some pretty crazy ways to "get rid of them" but does anyone have any remedies they know work? TIA!
