For those of you who are far post op from your procedure, have you used any skin firming lotions? Do you think it helped? Or is it a waste of time and money? I do realize everyone is different, but I wanted to see different thoughts on this.

I haven't used any lotions specifically for firming your skin. I simply use a sea salt scrub in the shower to exfoliate, and then a body lotion while I'm still damp. In the winter I was also using a body oil. I don't know to what extent firming products help. I think whether or not you develop loose skin depends on various factors, such as how rapidly you lose weight, how much weight you lose, how long you were at your highest weight, and your age. I've lost weight at a very s l o w pace, but the silver lining is absolutely no loose skin.

You might want to look on MakeupAlley and see if you can read product reviews for lotions that are supposed to firm your skin. It won't be as specific as feedback from here, of course, but there are far more people who use that site.

Salt scrub is supposed to help before whatever you use. Everything's individual to amount of loss though.
