I would like to know what is the best none invasive treatment for crepey skin, on upper arms and inner thighs, after weight loss? Is it Exilis? A health issue caused me to gained a lot of water weight. I lost the weight very quickly, once I eliminated salt from my diet. I exercise religiously 5 days a week, doing both cardio and heavy weights, so I have good muscle mass. Unfortunately, I now have crepey skin on my upper arms and inner thighs similar to the picture.
