Red Velvet's Irene went makeup free. 

On the February 14 airing of SBS' 'We Will Channel You,' Irene lost the battle against MC Kang Ho Dong. As the penalty, Kang Ho Dong got to paint Irene's face with black ink to stamp her face. 

Following the penalty time, Irene went to the sink to remove the ink and ended up showing her bare face. 

Check out the scene from the show in the clip above.
