No Pruning
Skin can become wrinkled or prune-like when exposed to prolonged water immersion, such as during a long bath. This phenomenon is caused by the nerves beneath the skin. However, if there is nerve damage or other related issues, the skin may not exhibit this pruning effect.
In this person’s case, they have one finger that does not prune, likely due to some underlying nerve-related condition or damage. This unique characteristic may appear peculiar or unusual, but it has a certain cool and distinctive quality.
