Kim Jong-un had paid a visit to the Pyongyang Cosmetics Factory together with his wife Ri Sol-ju and sister Kim Yo-jong.
Ms Kim meanwhile can not be identified in the photographs, but the report by state news agency KCNA mentioned she was present along with other top officials.
In another glowing endorsement for the leader of the rogue nation, the Korean Central News Agency (KCNA) said Kim was very impressed by the gold standard cosmetics factories.
It's unclear exactly when the images were taken, as they were released without a date.
It was reportedly his second public appearance with wife Ri Sol-ju this month. In that regard, Kim has flouted tradition by appearing publicly with Ri. Kim apparently also said during the outing that the products produced there help North Korean women "be more attractive".More news: Selena Gomez Cries in First TV Interview About Life-Saving Kidney Transplant

While we're used to seeing the hermit kingdom's supreme leader cheerily visiting bomb makers and giggling on the sidelines of ballistic missile tests, he eschewed those macho environments to enjoy the pastel colours and soft lighting of the Pyongyang Cosmetics Factory.
The day before the cosmetics factory visit, US Defence Secretary Jim Mattis, said America would "never accept" a nuclear-armed North Korea during his visit to Seoul.
"This can help women fulfil their dreams of becoming more handsome". Her exact age is unknown and she rarely makes public appearances.
Tensions have been high on the peninsula with the North conducting its sixth nuclear test in September and launching multiple missiles capable of reaching the mainland of its "imperialist enemy" the US.
Two of seven North Korean agents were arrested over the alleged plot to kill Kim Han Sol, whose father Kim Jong Nam was assassinated in Malaysia earlier this year, the newspaper said, citing an unidentified person familiar with North Korean issues.
