You cause a creature or an object that you touch to grow older or younger for the duration. If the target is unwilling, it can make a Constitution saving throw. On a success, the spell has no effect.

You select how much older or younger the target looks (for example, “10 years older” or “as an adult”). You can’t otherwise change the target’s appearance other than those details directly associated with aging (for example, a target’s hair might turn gray or the target might develop liver spots). This spell allows children of creatures that are Medium or smaller when fully grown to grow one size category to the normal, adult size of that type of creature, but otherwise the selected age increase doesn’t alter the creature’s size. A change in size doesn’t alter the target’s ability scores.
