Leaders Cosmetics was established in 1986 and listed on KOSDAQ in 2003, and it operates an unusual dual structure spanning cosmetics and corrugated-board packaging.
In its most recent fiscal year, corrugated board (double-faced, double-wall and single-faced board) accounted for roughly 67% of revenue and effectively served as the company's core revenue base, while cosmetics products such as mask packs and basic skincare made up about 21% and merchandise sales about 11%.
The cosmetics unit positions itself as a cosmeceutical specialist built on clinical experience from the affiliated Leaders Dermatology Clinic, manufacturing products through an integrated planning-R&D-production-distribution system at its Aqua factory, which the company describes as the largest domestic facility dedicated to mask-pack production.
Products are sold in roughly 30 countries through drugstores, supermarkets, convenience stores, department stores and duty-free channels.
The corrugated-board business was spun off into a separate entity, Sansung P&C, in 2016 and then re-absorbed back into Leaders Cosmetics in 2022, reconstituting the dual-business structure under one listed entity.
The cosmetics industry is described as facing intensifying competition from new entrants, while the corrugated-board business continues to see modest growth on the back of rising packaging demand from e-commerce and substitution demand away from styrofoam.
In March 2026, the company entered the prescription-drug distribution business for the first time by signing a domestic exclusive-sale license agreement with KONEX-listed drug developer EnsolBioscience for the osteoarthritis treatment candidate E1K.
Under the deal, if E1K clears Phase 3 trials and receives final product approval, Leaders Cosmetics would obtain full rights to domestic sales, distribution and marketing, and the company said the agreement secures a new growth driver through a validated drug pipeline.
