(X-post): Dry brushing of the skin

Interested to see if anyone else has tried routine dry-brushing of the skin pre- and post-op?  If you have, do you feel it's helped the condition of your skin at all?  I have a friend that swears by it and there's a lot of info out there about how it helps clear the lymphatic system.  So I'm willing to believe it's probably OK for general health purposes.  

But does it really help people like us whose skin has been stretched to the max and damaged through the gaining and losing of large amounts of weight?  I'm doubtful...

I don't dry brush, but I do scrub my skin in the shower with soap free shower gel and a cactus fibre cloth in the shower followed with Bio Oil.  I don't know whether it has made any difference as I don't have a comparison, but Im pretty happy with how my skin in considering that Im 40 and have been seriously overweight since childhood.
