Jaskier is as baby faced at eighteen (1x02) as he is at forty (1x06). Logical deduction suggests if he was human, he stopped aging about this time.

Hmmmmmmmmmmm, what else happened when he was eighteen? Did he maybe come into possession of a (probably) magical eleven lute gifted to him by the KING OF THE MAGICAL CHAOS WEILDING ELVES that had probably been steeped in layers of enchantments? Maybe even one that was deliberately placed in order to keep the bard young and thus chattering a certain stoic Witchers ear off from then until eternity because Filivandral sees opportunities and embraces them unlike someone else that will remain nameless.
