A black pearl-like skincare serum that melts into liquid upon contact with skin is drawing attention at a new beauty pop-up in Seoul’s trendy Seongsu district.

When visitors placed the glossy black beads on their palms, the solid spheres dissolved with body heat into a liquid serum. Many attendees compared the product to caviar or jelly as they filmed the experience on their smartphones.

The pop-up store, which opened on May 27 along Yeonmujang-gil in Seongsu-dong, marks the debut of premium derma cosmetic brand ADESII, launched by Hanmi Science. The storefront, decorated with oversized black pearl sculptures and helium balloons, stood out even among the district’s crowded beauty pop-up scene.

The showroom-style space was designed to showcase the technology and concept behind the new brand. According to the company, the project had been in development for about two and a half years since October 2023, representing Hanmi Science’s first major expansion of its pharmaceutical R&D expertise into the cosmetics market.

The brand’s first product, the “Black Pearl PDRN Neo Serum,” differs from conventional liquid serums with its salmon roe-inspired bead format. An ADESII official said the company uses a specialized process that drops the serum into individual beads before immediately cooling them, allowing each pearl to contain a precisely measured amount.

The application process also drew attention from visitors. Depending on skin type, users apply two to five beads onto their palms, where the pearls melt into liquid before being absorbed into the skin. Demonstration booths at the venue attracted long lines of visitors eager to test the product on their hands.

The product’s distinctive black color does not come from artificial pigments but from “Black PDRN,” an ingredient extracted from blackberries, the company said.

Hanmi Science highlighted its proprietary antioxidant ingredient “H-EGTI” as the product’s core technology. The patented material combines the naturally derived amino acid ergothioneine, or EGT, with a flavonoid ingredient called Resistress to strengthen antioxidant functionality.

According to the company, the ingredient is designed to detect early oxidation signals and suppress reactive oxygen species. Internal clinical tests reportedly showed antioxidant performance more than twice as strong as EGT alone. The formula also replaces purified water with more than 50% collagen water.

“While conventional anti-aging products focus on improving wrinkles that have already formed, ADESII concentrates on early-stage skin aging prevention and antioxidant-centered care,” a company official said.

The official added that the product was designed so consumers could notice changes within two weeks, roughly half of the skin turnover cycle.

With the launch of ADESII, Hanmi Science plans to accelerate its expansion into the business-to-consumer market. The company said it will begin sales through its online mall before expanding distribution to channels including Naver Smart Store and Olive Young.

Industry observers say the move reflects a broader trend of pharmaceutical companies entering the cosmetics sector by leveraging their R&D capabilities for consumer products.

The Seongsu pop-up store will run through June 1.
