Stretch mark care for my thighs and abdomen

I have severe stretch marks on my stomach and thighs due to weight gain from childbirth and rapid weight gain.

I do regret not taking better care of myself when I was pregnant, but I can't turn back time...

It's no use regretting it now, haha.

I would like to try managing it even now.

Will applying stretch mark cream consistently definitely help?

Looking at the ingredients of stretch mark cream, it seems like there are a lot of ingredients that are mainly effective for moisturizing.

Even if it's not a cream specifically for stretch marks, would applying something like a highly moisturizing body lotion be effective in improving stretch marks?
