How did narcissus lose his beauty?

Narcissus lost his beauty as a result of his unyielding obsession with his own reflection. According to the myth, he became so enamored with his appearance while gazing at his reflection in a pool of water that he neglected to eat or drink, ultimately leading to his demise.
