The roller massager is a galvanopair (silver roller-cathode, zinc alloy insert - anode). The presence of the galvanopair allows you to produce electric vitamins - microcurrents without wires and batteries ≈30-50 µA. Analogue of microcurrent therapy in a beauty salon.

Electric vitamins make your skin beautiful.

In addition to the massage effect, which improves blood circulation, the original design of the roller provides the formation of electric vitamins - microcurrents without wires or batteries due to the reduction (REDuction) processes on the silver-plated (10 µm) roller and oxidation (OXidation) processes on the zinc insert.

Daily use of the biotrenager prevents the formation of expression lines, stimulates the biosynthesis of collagen and elastin, provides lymphatic drainage, increases the effectiveness of any cream.
