decoration

I use a peter child burner for adding detail on some of my carvings.Some are posed in the sculpture forum.
They say that pyrograpy work fades with time if this is the case what do you do to preserve it all i do is just seal it with varnish? any ideas?
a quick example of one piece i have done just to show

the burning does fad out in direct sunlight and weather , even when varnished,
