I'm 26 and people still think I'm 18. Damn braces don't help either...
Looks like lots of makeup and good ol' Asian aging... to me she looks like in her 30s but my mom looked like she was in her 30s well into her 40s. Us Asians don't really "age" until around our 60s when we begin the rapid change into shriveled up prunes.
EDIT: BTW, I noticed lots of makeup and heavy lighting... masks signs of aging quite well... she'd prolly look good in person but older
Oh CRAP... wait... are we doing age by Western age count or "Eastern"... cause if it's the way wacko Taiwanese do it... 43 is in her late 30s.
