Is it possible to treat stretch marks on the stomach? I am curious about the process.

I gained weight mainly around my belly after giving birth to my first child, and now I have stretch marks.

And with my second pregnancy, as I gained weight, my belly split open as if it had been ripped apart.

It was pink at first, but now it has turned white.

I saw on Instagram that a skin care shop is doing stretch mark treatments with a skin tone.

I'm curious how hospitals treat stretch marks.

If anyone knows the procedure and price range, please share your reviews.
