Usually a person’s fingerprints do not change during the lifetime. Minor and superficial cuts that he’ll do not affect the pattern formed by the ridges that cover the skin of the fingertips. Ridges are the impressions which make fingerprints. However, extensive or deep wounds, severe burns, surgery or disease may destroy these ridges and lead to a change in fingerprint patterns. Deep wounds damage the underlying dermis of the skin and healing often leads to scar formation. Since scar tissue does not show secondary modifications such as hair, it does not show the ridge pattern either. However, these are extremely unlikely events and usually fingerprints are for life.
