I do it, but not regularly. It does help me with my very dry skin issues. I'm allergic to most soaps (except for the pure olive oil ones without scents), so I dry brush at least once a week. Wish I remembered to do it more often. I do like how my skin feels afterward. I dry brush everywhere I can reach, then rince off with warm water. Then I apply almond oil on my arms and legs where most of my driness is the worst. I also get a body scrub and massage at the local day spa once a month.
I lost nearly 50 lbs a few years ago and my skin really started sagging. I noticed recently that my skin has tightened up quite a lot, and I think the brushing has helped some. I'm 50, menopausal and starting to lose elasticity in my skin. I think I'm prepared to lose the next 50 lbs now, and I plan to step up the dry brushing and body scrubs so my skin will shrink faster this time. We'll see what happens.
