What do y’all use for deep stretch marks?

Just noticed I have a ton of deep stretch marks on my ass 😩 I have been using palmers stretch mark lotion and bio oil on my stomach as preventatives and don’t have any stretch marks there so far. Butttt I don’t know how long these stretch marks on my ass have been here for and I’m scared they’re past the point of restoration 😭

What do y’all use to lighten stretch marks??? TIA
