It won't tighten up much at all, if any. Surgery really isnt that expensive, plus you can finanace it and only pay a small ammount a month. I had a full abdominoplasty/lipo and it was only $5700. The surgery is well worth the cost. But then again, i had lost almost 200 pounds at the time. Your skin probably isnt anywhere near how gross mine was lol. Take care and good luck!
