i use msm but i havent had surgery to tell you if it would work on helping with sagging skin i use it to prevent wrinkles seems to be doing a great job at that lol. make sure u get msm that is distilled and not crystalized the crystalized can and probably does have impurities in it. i get mine from http://www.youramwell.com/aboutmsm.html
