absorption THROUGH skin....

the theory is....  that you CAN absorb minerals through your skin....  that you CAN absorb vitamins through your skin....

AND....

your skin knows how to manage the microneutrients that you absorb....  that....  you cannot aborb too many microneutrients through the skin....  so....  absorbing microneutrients through skin....  gives the liver a break....  because the liver has to filter out microneutrients....  when you get too much....
