I am soooooo hooked on dry body brushing!
I have been doing it daily, in the am right before I shower, for about 4 months now.
And it does, to some degree, help with cellulite, that isnt bs
I strongly encourage people to understand they lymph system better. Here is a decent reference for a quick overview: http://en.wikipedia.org/wiki/Lymphatic_system
In short, your lymph system runs right under your skin, has no pump (like your heart is for your blood circulatory system), and is responsible for an awful lot of work related to weight loss. Notably, for the elimination and transportation of fat as well as cellular waste.
Dry brushing is one of the things you can do to promote lymphatic drainage. This isnt a magical cure for cellulite, but it does help. It also helps with edema.
