Wrinkles

Wrinkles

Water-induced wrinkles are not caused by the skin absorbing water and swelling. They are caused by the autonomic nervous system, which triggers localized vasoconstriction in response to wet skin, yielding a wrinkled appearance. A 2014 study showed no improvement in handling wet objects with wrinkled fingertips.
