They stop aging at 20, I think it was Matsuno who stated this, also, they don't stop aging, they just do it really slow, if you ask me except for the short haired male, which would be the younger face type, they don't look like teens, they look just like the females, in their early 20s.

My guess is we are gonna get a face 4 that will be still young but a bit older than the others (mid late 20s?), just like you can make f. viera face 4 into a more mature looking face with the correct settings.
