According to a company spokesperson:
"We chose Girls' Generation's Seohyun as our model because her smart and fresh image fit what the brand is aiming for.We are expected her to add onto The Face Shops's new generation-like fresh and feminine charms.
She will begin filming her first CF for the brand this October,alongside ss501 member Kim HyunJoong.
Honest,they couldn't have picked a better person for the job.When it comes to skincare,maknae knows her stuff alright i.e. skin cells begin to grow at 10pm and stops at 2am.....and anda better BELIEVE IT because Seohyun says so!
