Fingerprints Remain the Same for Life

Reportedly, fingerprints do last a lifetime. You can try burning them with acid, cutting them off or wear them out, but eventually the skin will grow back.

The patterns are permanent, but can wear down. Builders who lay bricks and people who frequently wash dishes by hand lose some of the detail. Once they stop these activities, the ridges will grow back.

As fans of crime movies will know, from time to time people have tried to change their fingerprints patterns artificially.

A deep cut through the outer layer of the skin, the epidermis, and down to the dermis leaves a scar that will change a fingerprint, but not make it any less unique.

People have also sought to erase their fingerprints by burning the finger-tips with fire and acid, as the notorious 1930s American gangster John Dillinger did. It works for a while but the skin grows back.
