Stretch marks...ladies please help!!?

I'm a small girl 5'4,135lbs...within the last few months my lower half ( & thighs) have just been getting bigger & bigger, I'm talking about 2 sizes away from Kim Kardashian :(...I have quite a few stretch marks (dark purple color) on my outer and inner thighs and on my , I've been using Palmer's Stretch Mark lotion...has anyone had any luck with this? Or anything else you can recommend? I used to be happy with my body until now. I'm sure some ladies can relate to this and I would love to hear if anyone has had luck with any products or treatments. Thanks!
