Hi there,
i am no expert, but I have gone through exactly the same story as you are, so here is what I can say based on my personal experience.
I was 240 pounds, hated it and decided to lose weight. I exercised, dieted and made my way through to 130 pounds that I am now.
The problem is: I have lots of excessive skin on my belly, breasts and upper arms with streach marks all over my body, like on the back sides of my knees, shoulders, etc. And also, the rest of my skin doesn't look healthy, I mean it doesn't have the elasticity like it used to.
So, I am going to have a breast lift this spring, then probably next winter a tummy tuck. I would also like to have the bat wing reduction to remove the excessive skin and streach marks from my arms. But this will probably be well beyond my financial means. Anyways, for the two coming surgeries I am looking at somewhat $11,000. And the scars will be permanent and visible.
So, my advice. Try to reduce your weight, but don't go down as much as I did. You are about 260 pounds? Try to get to 180 pounds or so, and try to keep it stable for a while to see how your body and skin is taking it. And use moisturisers and strech mark creams.
Hope this helps.
Good luck,
el
