Korean portal site DC Inside recently held a poll from the 8th to the 15th asking its users, "Which female celebrity has the best proportioned face that doesn't need to be altered?" 

Out of 4,005 votes, Girls' Generation's YoonA garnered an impressive amount of 1,659 votes (41.4%).  

Actress Park Shin Hye came in second with 1,253 votes (31.3%) while actress Sung Yuri came in third with 143 votes (3.6%).  Since first appearing in the entertainment world, all three female celebrities look essentially the same, so they're receiving a lot of acclaim for their pretty, unchanging facial features.

Following the top 3 were Han Hyo Joo, Kim Tae Hee, and f(x)'s Sulli.
