Does anyone have suggestions for treatments or creams that encourage skin to go back where it belongs after weight loss? I feel like plastic surgery is inevitable, but in the meantime I'd like to do what I can within the limits of age and time.

check your local salons, and spa's for something called Laser Lipo, I have signed up for sessions (christmas sale), and it worked wonders for my friend to help tighten her skin some (especially arms)..... though you are right, plastics is on the horizon for most of us.
