I want to lighten and/or fade my stretchmarks, any good regimens or methods I could use?

Okay, um, recently, I went through a major slump in my life. I had serious depression. My daily day schedule would consist of waking up, showering, eating most of the day, laying in bed most of the day, and going back to sleep, only to repeat it the next day. Well, a few weeks back, one of my closest friends and me had a heart to heart slash pep talk that made me feel ten times better about myself. I got out of my depression, but I had some lasting after effects. One was a new belly, two was a group of stretchmarks on my upper arms, upper back, waist and lower back. I've worked off the belly, but the stretchmarks are persistent. I know that you can't just get rid of stretchmarks, they're pretty much with you for life, but I do know you can lighten, fade or cover them up. Any regimens or methods to do these?
