[Question] Is there a treatment to remove stretch marks?

In the past, I suddenly gained weight and developed stretch marks. As far as I know, newly formed stretch marks appear red, while older stretch marks look white and have a crack-like appearance.

I tend to be quite fair-skinned. So I don't think applying stretch mark cream will make them disappear, and that's a bit frustrating.

The area of concern is my thigh. It is connected to my buttocks, and there are also some stretch marks on my buttocks. I want to get rid of the stretch marks because I find them unsightly, but I don't know how to do so. Are there any options like laser treatments at a dermatology clinic?

Please share any tips if you have experience in getting rid of stretch marks.
