The Stretch Mark Blues

Hi everyone! So, since sophomore year of high school, I had gained like 60 pounds by my senior year. (I weighed about 130 and went to 190) And I have done some serious damage to my stomach. It's just laced with stretch marks. I've lost 20 pounds and was hoping maybe they would somewhat get a little less dark. Does anyone have tips on how to lighten them up without going to a doctor? I know I can't completely erase them, but I would feel a little more confident in myself if they were a little less noticeable. Please and thank you!
