Crazy Diamond can't revert someone's age, since aging is not considered an injury or a wound/damage.

It could only restore something back to its previous state if something that could be considered as "damage" is involved. "Damage" could involve a variety amount of things, such as cutting, bashing, chemical reactions, fire and explosions etc, but it does however, not involve aging because it's not foundamentally considered as a damage literally or scientifically.

Reverting age however, is something Alessi's Sethan could do.
