How would the space environment affect human fingerprints compared with Earth and deep underwater?

Human fingerprints are generally considered permanent, but the environments humans can occupy differ dramatically.
I am interested in how the space environment compares with other extreme environments rather than in fingerprint identification itself.
Compared with conditions on Earth and deep underwater, how are human fingerprints affected:
inside a spacecraft,
and during a spacewalk in outer space?
Specifically, does the space environment change only the ability to leave or recover fingerprint impressions, or can it also temporarily or permanently affect the skin ridges themselves? What physical or physiological mechanisms are responsible for any differences?
