The large and powerful muscle surrounding the lips
(Orbicularis Oris) might be compared to the hub of a
wheel, with many "spokes" of muscle networks
fanning out from it, which in turn are connected to many lesser networks covering the entire face and neck.
It is virtually impossible to move the lips even
slightly without activating this multitude of muscles,
however slightly. The stronger the resistence to this
movement, the harder they all have to work.
No other flexing face exerciser on the
market today has the strength to give the brow and upper eyelids the same powerful workout as the rest of the face - with no greater strain and in half the time as any competing product.
