I'm 33 & naturally thin. I weight train, am working to gain weight/muscle, drink water, exfoliate, eat great. My arms aren't sagging/loose, just my elbows. I saw a procedure online - the Dr made an insicion just above the elbows & tightened JUST the elbow skin. Is this a good option? It would take too much filler to plump them, I'm not a good candidate for fat transfer, I don't need a brachioplasty & I'm not sure a tightening laser would have much effect. Any advice would be greatly appreciated!
