yeah nothing prevents stretch marks. it has to do with genetics and your skins elasticity.

I use bio oil and coco butter

Cocoa butter

Nothing prevents stretchmarks.

Mederma. It's 35-40$ though

I use cocoa butter stretch mark formula. I got it at wallgreens or rite aid. Its like $8 for a nice big thing of it and it lightens them and helps prevent/get rid of them. I like it alot. Theres a certain one thats only for use after pregnancy that works I heard its from ItWorks company. I cant remember what its called tho lol.. Im sure you could easily loo it up though 😊
