Kim So Hyun continues to make us wonder how she can be so beautiful at such a young age with behind-cuts from a CF filming!

The photos are from the set of her shoot with cosmetics 'Peripera'. The brand definitely chose the right model as she displays her vibrant charms and her flawless complexion. These products she's demonstrating using are sure to sell out because who wouldn't want to achieve that youthful yet mature look that she has?

In related news, the young actress also recently celebrated her 7th year since debut (wow!).
