Aluminium is highly reactive and the metal quickly forms an oxide layer, yet the metal shines why?

Because the "passivation layer" of aluminum oxide is very thin, so it doesn't interfere with the luster of aluminum.

the oxide forms a thin layer that protects the metal underneath by slowing further oxidation, but given some time it will become dull

the aluminium oxide layer is bright and white. so aluminium shines in light although it has a thin film.

Because it has been highly polished then anodized which changes the crystal structure which is highly corrosion resistant.
