1. A bleaching device for bleaching parts of the body, the device comprising:
an electrophoretic wave current generator with a varying modulation;
a means for transmitting electrophoretic current from the wave-current generator to the part of the body to be bleached;
a means for creating a non-traumatizing field through the part of the body to be bleached, said means for creating comprising
a plurality of electrodes and a conductive gel, said field being selected from a group consisting of electric, electrophoretic
and electromagnetic;
a means for containing said conductive gel in contact with said plurality of electrodes and the part of the body to be bleached
so as to cause a continuous field;
an active product suitable for bleaching, said active product being sensitive to the electrophoretic current;
means for activating said product, said means for activating being selected from a group consisting of heat and light; and
means for reversing polarity of said electrophoretic current, extracting coloring molecules degraded by said active product
and non-degraded or non-reacted bleaching molecules of said active product from the part of the body to be bleached.
