I haven’t put anything on my stomach but I have stayed super hydrated!!

Also, I know people who've had many kids and didn't use anything and don't have mark...still believe it's genetics overall.

Can't really besides gain weight slowly, and keep the skin hydrated as well as drinking plenty of water. I use Aveeno and cold pressed rose hip oil. Haven't had any new ones so far 🤞🤞🤞

I was told bio oil can help prevent them. I didn't start using it until after I had my son and it's not doing much for the ones that are already there but it's worth a try to keep you from getting them.

I used cocoa butter and I didn’t get any. Personally the first one only gave me stretch marks on my love handles, after that it stayed the same but I just continued using that butter. Really helps.

You can't. Even the expensive oils like bio oil etc will not prevent it.

Coconut oil

I don't believe there is a way, either you get em or you don't... from my count. Always keep moisturizered no matter what, I'm sure that can at least help the smoothness...
