No, you cannot fundamentally change your fingerprints. While you can temporarily alter them through injury or damage, your fingerprints will regenerate, essentially returning to their original pattern.
Understanding Fingerprint Regeneration
Your fingerprints, formed by the pattern of ridges and valleys on your fingertips, are largely established before birth. As stated in one source, "The pattern of loops and whorls on your fingerprints was fixed three months before you were born." Although you can scar or temporarily remove them through actions such as:
- Deep cuts
- Abrasion
- Acid exposure
- Certain skin conditions
These changes are temporary. Fingerprints lost due to these factors will regrow within approximately one month, returning to their original pattern. [Source: Reference material stating that fingerprints lost through injury grow back within a month.]
Several sources confirm that while damage can alter fingerprints temporarily, the original pattern will regenerate. One Reddit discussion highlights that fingerprints regrow even after deep wounds. [Source: Reddit - Do fingerprints restore exactly the same after a wound?]
Methods of Fingerprint Alteration and Their Limitations
Attempts to permanently alter fingerprints, such as using acid or deliberately cutting the fingertips, are extremely damaging and will lead to permanent scarring. However, even such severe damage will still result in the regrowth of fingerprints, albeit with scars that may affect the readability of the prints.

While you can add additional fingerprints to devices using fingerprint authentication, such as smartphones and computers, you cannot change the unique patterns of your existing fingerprints. This is frequently a source of frustration for users attempting to modify their fingerprint settings on devices.

It's crucial to understand that attempts to drastically alter or remove fingerprints are highly impractical, dangerous, and will likely not result in the desired outcome.
