Your fingers 'prune' the exact same way each time, study suggests
- Researchers at Binghamton University published a May 2025 study showing fingers wrinkle in a consistent pattern each time after water immersion.
- The study tested three volunteers whose fingers were submerged in water for 30 minutes twice, 24 hours apart, to verify if wrinkle patterns repeated.
- Wrinkles form from blood vessel constriction controlled by the sympathetic nervous system, and because vessels remain mostly static, the pattern repeats predictably.
- Professor Guy German explained that since blood vessels remain largely fixed in relation to one another, wrinkle patterns develop consistently, a finding their research confirmed.
- The findings suggest possible forensic and diagnostic uses, such as identifying nerve damage, though additional research on larger groups remains necessary to confirm results.

Do Wet Fingers Always Wrinkle Exactly The Same Way?
After a long bath or dip in the pool, your fingers probably look like pruney raisins. That wrinkling isn't random; it follows the same pattern every time, according to a new study from Binghamton University. The wrinkles that form on our fingertips after soaking in water create a unique topographical pattern that repeats consistently, even across different days.

Mystery About The Way Fingers Wrinkle in Water Might Have an Answer
Upon learning about the blood vessels responsible for our water-soaked finger wrinkles, young readers of The Conversation's Curious Kids series had further questions for scientists: "Do the wrinkles always form in the same way?" one asked."And I thought: I haven't the foggiest clue!" recalls the author of the educational article, biomedical engineer Guy German from Binghamton University in New York . "So it led to this research to find out."…
