Can I improve loose skin with Derma Rolling/ Micro Needling? (photos)

In my office we have
been getting excellent results in the treatment of stretch marks by using medical micro-needling combined with human growth factor serums. We use motorized
micro-needling, not the derma roller, for a more even and more effective
result. Rollers such as the Dermaroller create a more
erratic pattern of "tears" through the skin due to the angle at which
the needles enter and leave the skin. This contrasts with the clean, more
evenly distributed vertical punctures seen with motorized micro-needling
machines. This has been nicely shown in studies done by independent observers
using clay models. Because
micro-needling has been shown to enhance delivery of topically applied skin
care products, we combine micro-needling treatments with human growth factor serums to
get the best results in the treatment of scars and stretch marks.The loose skin is much more difficult to treat and may require other techniques. In my office we have gotten good results in skin tightening using the Exilis radio-frequency skin tightening device.
