Old skin cells foster the skin's ability to excrete toxins through the skin. Dry skin brushing is an easy way to stimulate the lymph system, which in turn, enhances the body's natural detoxification processes.
Many years ago I went to an iridologist who recommended this for me. I bought a vegetable brush which she recommended since the bristles are neither too soft nor too stiff. It hurt at first and took some getting used to. I haven't done this in forever and really should get back to it so thanks for the reminder!
Cellulite is caused by built up toxins in fat cells and/or poor circulation. Dry brushing is good for increasing circulation and ridding the body of toxins so it makes sense that it would benefit.
Here's the directions:
The body should be dry and naked.
Using a natural fiber brush or loofa sponge, brush skin once or twice in the same direction, across every surface of the body except the face.
Do not scrub, massage, or rotate the brush on the body; just sweep it across the skin in long smooth strokes in the direction of the heart.
Brush up the arms from hands to shoulders, up the legs from feet to hops, down the back and torso, up the bullocks, down the neck, and across the shoulders.
The entire process should take no longer than a minute, and should be done while the skin is still dry.
An easy time to do it is before you take a shower.
