We don't know how old the SQ (or, as I'm starting to call her, Frostine) is, but some women look very youthful even into their 60s, so it's not implausible that she remained fairly 'youthful-looking' throughout the 28 years of the Curse.

Speaking of the Curse, it really doesn't seem at this juncture as if she had anything to do with it, and that she may have been in the Land without Magic before Regina cast it, in which case she could very well have been Emma's adoptive mother (which is my pet theory right now).
