Anarchism Ho!
Not to mention the healing factor that all Fae have (the basis of 'Battle Healing' as it were). Might not be 100% but if their bodies are simply better at dealing with the daily wear and tear that everybody experiences; even discounting thier lifespan, they'll look youthful and 'perfect' a lot longer than normal.
Past mentions of the Faerie ageing process would suggest that they stay perfect right up until they turn into Yoda. Thereby becoming truly perfect.
Which does imply a baseline healing capacity sufficient to fully offset the usual wear and tear. Something that is probably gonna be pretty unpleasant for a lot of first generation Fae whose bodies always feel a little airbrushed to them.
