Stretch Marks

Hello ladies, I'm 26 4days & I started out at 100 pounds now I weigh 120, does anyone know what's great on stretch marks/ cellulite? I don't have any on my belly & just my butt & hips lol.. That's where I gained the most weight at lol.. I have never had stretch marks or cellulite ever in my life & I wondering if anyone knew of some great products? I have been using the "it works" stretch mark cream but ain't seeing that much of a difference.. I've always used coconut butter & coconut oil from day one for moisturizer. Thanks :)
