Any advice on how to prevent loose skin after surgery???

Try Palmer's Firming Butter. Works great.

Exercise, exercise, exercise.... build the muscle to replace the fat.

Remember it may not all go back as well....Depends on how heavy you are when you start...Elasticity of the skin....my weight has yo-yoed up and down 100 lbs here and there...and I have come to terms before surgery that it all wasn't going back... But surprisingly most of it did...minus a lil pooch belly and a lil flabby arms. ... Drink lots of water supports elasticity of skin

Some of this depends on your age, too.

There isn't a lotion or potion out there that will fix or prevent loose skin.

I was told it would depend on age as well and I have a loose belly as well as some lose skin on my arms....but i"m not complainin! I love my new body loose tummy and all:)
