What you need:
A natural, non-synthetic, bristle brush or loofah. It is preferable to use one with a long handle so that you can access hard to reach areas.
It is best to do your skin brushing on dry skin, before showering or bathing, so that you can then wash off any dead skin cells right away.
Using gentle circular counter-clockwise strokes, begin on the soles of the feet and move up around the ankles, calves, thighs, buttocks, abdomen, breasts/chest and back. Then proceed to the palms of the hands, around the wrists and up the arms and shoulders. You should always be brushing toward the heart. The face and inner thighs are sensitive areas and can be avoided.
The brush should not scratch but you should feel some friction against your skin.
Wash your brush in soap and water every one to two weeks to remove any accumulated debris.
