Hi
@Onelastshot, My highest measured weight was 344, but I probably reached a bit over 350. I had a panniculectomy between c-sections, while near that weight, but before DS. I didn't have any PS after DS - I honestly don't think any is needed, but I do intentionally keep to a certain weight to keep (smaller) curves matching my skin. (My chest deflates beyond a certain weight and perks up above the line. I don' really tend to have loose skin elsewhere even when I get to be a skinny Minnie.)
FWIW, I don't think the speed of weight loss is really a factor - I think skin resilience has more to do with age, genetics and duration/extent of being stretched. I was overweight for a decade, so that's a lot of stress on the skin.
All the best!
