Reality: it is an active, involuntary vasomotor response. The nervous system constricts blood vessels under the skin to form ridges—acting like tire treads to channel away water and improve grip on wet objects. Patients with severed median nerves don't wrinkle at all.

So theoretically there might be a possibility to acquire an ability to wrinkle myself at will? Cool!

Haha, unfortunately it's strictly controlled by the autonomic nervous system (same system as goosebumps and pupil dilation), so voluntary control is locked out. Would make a wild party trick though!
