Spring is here, which means it's that time of year in K-pop to go back to fresh cute concepts, and Lee Jong Suk did just that with his irresistible expressions as he got one with nature. Lee Jong Suk shared in the CF, "Ate well. Who? My skin," with his cute smile and clear complexion.

A rep stated, "Lee Jong Suk's clean and healthy image matches well with this advertisement's new campaign 'Good food makes healthy skin'. We were surprised by how Lee Jong Suk perfectly expressed [the campaign] after only seeing the content for the feeling of the ad before the photo shoot. The filming was completed in a friendly atmosphere, and the results came out well so we anticipate a big synergistic effect. More than anything else, Lee Jong Suk's clear and clean skin is the core factor in creating confidence in the advertisement's image."

Lee Jong Suk's medical drama 'Doctor Stranger' premieres following 'God's Gift -14 Days' on May 5. Check out his 'Skin Food' pictorial and CFs below!
