Hi,
the reason why tatoos fade away is simply that you are a living being! Your
body replaces dead cells with new ones, transports a lot of substances it
needs (oxygen, water, vitamins, ...) to the places where they are needed
and transports the "rubbish" as for example CO2 out. So the
parts of your skin where the colour of your tatoo is placed will be
replaced and in addition they become "diluted" or dispersed over a greater
area with time. Because of this explanation you see that there is
(probably) nothing you can do to prevent it from happening!
Bye,
Andreas
