Does it matter for your skin how fast you lose?

 Thanks sweetie! Hey, I think the lil furry buggers are cute! I'd rather have melty skin than a size 26 butt... tho the way it's going, I'm not going to have any butt at all.. Trying to do a lot of incline walking to work on that!

Hey!  You can do with your buttRuffles like I do with my belly skin!  That's what they MAKE scrunchies for!  Right?

I would dare say it's very subjective regarding skin improving after WLS.
Some people's skin has more elasticity to it.
I know women who have had babies and didn't get any stretch marks! 
(I hate them/LOL).  I got them bad with my first pregnany and more with each.
As for building muscle mass that's cool you did that but a woman with really
stretched (heavier than your HW) out skin may not achieve the same results
as but it certainly its worth it to build muscle mass because you burn more calories that way
and look more toned.
At 60, 4 pregnancies, 35 yrs. of being 100 lbs over weight, 
I think surgical skin removal will most likely be my only solution.
Not to say I won't lift weights though!

You are right about someone who was heavier, has stretchmarks coming out differently, or someone of a different ethnicity or skin tone even, but my answer was to your question of "typical." 

I just have no idea what typical is, especially here - because folks just tell us their skin is bad, or its better, but they do not show us!  Which I mean, they sure do not HAVE to, but it just means, I have no idea of what is or is not typical, you know?  I think my point to anyone who might listen is just that you do not ever know! 

I never know!  :{} 

I only got strechmarks from me.  :}  Durn nobody to blame!
