Adam once said on twitter that "all magical lands were affected in some way" (no, I can't find the tweet).

In addition, if you take a look at the continuity of all lands other than the EF, nobody has aged during the 28 years. Whether it be the spin-off characters (both from Wonderland and Victorian England), the Arendelle gang, the Camelot and DunBroch people, Zelena (who was in Oz), everyone is the same age before and after the curse.

The difference is the following:
 * For people within the Enchanted Forest that got taken to Storybrooke: they don't notice time is passing by until the curse is broken.
 * For people within the Enchanted Forest who got protected by Cora's spell: they don't notice time is passing by until the curse is broken.
 * For people who are frozen in time but are NOT within the Dark Curse reach: they don't notice time passes by, not even after the curse is broken. After the 28 years, their lives that have been in "pause" hit "play" again and they keep going without noticing 28 years happened.
