This stuff is amazing. I have been using it about 2 weeks and I can't say I have noticed and firming yet but it has made my skin look amazing. It has also made a difference in the stretch marks on my stomach (the bottle don't say anything about stretch marks but it does help them). My husband has even noticed how much my skin has improved since I've been using this. I've used it on my books, stomach, and booty. I have already bought a 2nd bottle to have on hand.
