After hours of nonstop dancing and singing on stage, you'd think anyone would be exhausted and look like a wreck - but not YoonA!

The Girls' Generation member was spotted leaving the concert hall after the girls' first stop on their world tour, '2013 Girls' Generation World Tour � Girls & Peace', and she looked just as fresh and gorgeous as she usually does! Her bright smile never left her face, and she waved, made a peace sign, and threw hearts at all her fans who were waiting for her until she slipped into her van. 

YoonA didn't look like someone who'd spent three and a half hours jumping around on stage - she looked like someone who'd just finished a spa treatment! Of course, her beauty was even more highlighted because of her gorgeous smile.

Super Junior's Eunhyuk also stopped by the concert hall to cheer his labelmates on.
