Rice bran is used in which type of exfoliant?

Rice bran acts as a physical, or mechanical, exfoliant because its bran particles provide real friction when massaged onto the skin. This physical action helps slough off the outer dead cells. It doesn’t rely on enzymes to digest keratin (that would be enzymatic) and it doesn’t use acids or other chemicals to dissolve bonds between cells (that would be chemical). So the best fit is a mechanical exfoliant, since the effect comes from the abrasive, brushing-like action of the rice bran particles.
