Please tell me a sure way to get rid of stretch marks (recommend from experience).

As I spend more time sitting down after getting married

My calves often swell, and they also itch because I've gained weight. The stretch marks that used to be red are turning white...

Since my weight has fluctuated so much lately, it feels like my stretch marks have gotten deeper. I'm trying to lose weight by doing walking or using an indoor bike that suits my body condition, but it feels like dealing with stretch marks has become a lifelong challenge.

What is an effective method to get rid of stretch marks?

If anyone has succeeded based on their experience, please let me know.
