Try bio oil. It's helped me a lot with mine from both of my girls. But as the ladies above said, they'll fade mostly they don't just go away, so it is best to think of them that's positive like a mama tiger her earned her stripes or well deserved war wounds.
I think they mostly fade but not go away completely.
I think of them as hard earned war wounds.
Like with scars they will fade over time. Depending on how bad they are will determine how much they fade and how fast. There are products sold that are supposed to help this process but I haven't found any that seem to make a difference.
