What Can I Do For Crepey Leg Skin That Has Lost It's Elasticity?

I am only 31 and have crepey, snake skin covering my legs. I have lost collagen and the skins elasticity has depleted by the looks of it. When I pull up my leg skin it goes away. I have tried microdermabrasion for this and microphotothereapy and none of it works. I am thinking Laser will help this. My mom has this very bad 10X worse and she is 60. How do I get rid of this. PLEASE help me. My legs look like 40.
