REJURAN COSMETICS, a dermocosmetic brand from a Korean pharmaceutical company, is marking about one year since its full-scale launch in Japan with its first-ever collaboration campaign with the TV anime The Apothecary Diaries. The first installment is a pop-up event at @cosme TOKYO, running for seven days only from Wednesday, October 14 to Tuesday, October 20, 2026.
The event blends the world of The Apothecary Diaries with the brand's beauty experience. Visitors can enjoy a puzzle-solving game alongside protagonist Maomao, and the pop-up also offers campaign-limited collab products, collab items, and rewards for clearing the puzzle. Information on the second and third installments of the campaign will be posted on the official site in stages after the pop-up ends.
The TV anime series began airing in October 2023. Its third season is scheduled to air from October 2, 2026, split into two cours, and a theatrical film is scheduled for release on December 11, 2026.

A web puzzle that leads into the pop-up is also running. Clear both the web puzzle and the puzzle at the pop-up venue, and you receive an additional reward on top of the pop-up venue clear reward.
Puzzle Story
"Night after night, the sobbing voice of a vengeful spirit can be heard from somewhere..."
Maomao overhears a strange rumor in the pleasure quarter. She remembers being caught up in a similar incident back in the rear palace, when the story went that "a female ghost is dancing on top of the castle wall." Better to stay out of it, she thought at the time.
Then a masked nobleman appears. "There is something I want you to take a look at."
The key to the "curse" is the "Golden Elixir" (黄金の秘薬). Can you uncover the truth behind the curse and find the "Golden Elixir"?
Note: The expressions in this story are for dramatic effect. The product is not a drug or quasi-drug.
