Nana is once again the model of cosmetics brand 'DHC'.
She was chosen as the model for the line in 2014, and she's been renewed as its model every year since then. She's been promoting the brand's healthy beauty image, and has been once again chosen in 2017 for the fourth year in a row.
DHC said, "We are continuing to work with Nana for the 4th year in a row because Nana's clear skin and healthy, confident image fits the best with DHC's brand concept. We're going to have an active marketing strategy this year."
