The Deepest Chamber of Our Science
The deepest chamber of the Group's technological narrative — and the place that truly sets us apart from other luxury beauty groups.
FIVE CORE TECHNOLOGIES
Technology Architecture
Five Pillars of Our Research
02
Multi-Peptide Signaling Technology
Multi-Peptide Signaling Technology
One of the core ingredients of the 12th-generation revitalizing complex — the core of the Bijin Privé flagship intimate-care line.
03
Ceramide Technology
Ceramide Technology
Skin barrier repair — applied across product lines, and the chemical foundation underpinning the Group's promise of "year-round stable skin."
04
Low-Molecular Hyaluronic Dual-Delivery
Low-Molecular Hyaluronic Dual-Delivery
Resolving the limitation of conventional hyaluronic acid that "only floats on the surface" — the Group's proprietary delivery technology.
05
12th-Generation Revitalizing Complex (Spring 2026 launch)
12th-Generation Revitalizing Complex
The Group's next-generation flagship ingredient platform — integrating the technologies above; the core of Bijin Privé.
⭐ THE GROUP'S CO-FORMULATION CAPABILITY
Co-formulation is science,
and also art
"A single active is easy to obtain. But getting 5, 10, or more actives to coexist stably at room temperature, without decay, in mutual synergy — this is the core technological asset of a century-old group."
- 01Room-temperature molecular activity stabilization (no cold chain required)
- 02Multi-active synergistic formulations
- 03Long‑term stability validation of co-formulation processes
- 04Passed down internally, generation to generation — not patented, never disclosed
⭐ DUAL-PROTECTION STRATEGY
Patents to defend the boundary,
the vault to defend the core
The Moat Behind the Wall
PUBLIC LAYER
80+
Proprietary Patents
Open protection through patents, preventing infringement by other companies — this is the "boundary" of the Group's technology.
VAULTED LAYER
600+
Permanently Vaulted Core Formulations
Kept internally as a permanent asset of the Group — not patented, not disclosed, not licensed, and passed only within the Group across generations. This is the "core" of the Group's technology.
R&D COLLABORATION NETWORK
Academic collaboration centered on Kyoto
- Kyoto Life Sciences Institute — the Group's technological hub, founded in 2014.
- Research collaboration with 9 universities in Japan (academic collaboration, not investment).
- Long‑term clinical collaboration with the Japan Society of Obstetrics and Gynecology (JSOG, 1949).
- R&D synergies within the strategic investment portfolio (a capital-side collaboration; see Investment Portfolio).
