How far in advance should I start using tummy butter for stretch marks? I'm thinking I should put it on my tummy, boobs,…

Now

I used it before I got pregnant but I used it throughout my pregnancy and didn't get stretch marks.

I used coconut oil though

Around 20weeks !

Yea even put it on thighs cuz I didn't get stretch marks on my stomach at all but I sure did get some on my inner thighs
