JUNSUI MugenThe whole library, one pour.
Mugen gathers our four flagship molecules — HA, PDRN, GHK-Cu, Niacinamide — into a single lyophilised cake, held dry across four ampoules. Four pure diluent ampoules complete the kit. Each session begins with water meeting the cake; nothing waits in solution, nothing degrades on the shelf.
Four pathways, one matrix — the systems-based stack. A foundational hydrator and a foundational vitamin, scaffolded by two regenerative actives, held dry until you ask for them.
Four flagship molecules co-lyophilised into a single luminous cake — HA, PDRN, GHK-Cu, Niacinamide.
Pure buffered diluent, pH 6.8 — wakes all four pathways at once.
One dry + one wet = one session. Activated at the moment of use. Spent within the hour. The molecule never waits.
The kit, observed quietly.
The ampoule opened. The box that holds eight. A hand that knows the ritual. The serum at the moment of pour.

Six unhurried steps.
- 01
Prepare — lay out one dry ampoule, one wet ampoule, and a small clean dish on a calm surface. Hands washed; face cleansed and patted dry.
- 02
Unseal — lift the gold foil disc from one dry ampoule and one wet ampoule. The butyl septum stays in place.
- 03
Pour the diluent — gently pour the contents of the wet ampoule into the dry ampoule, running the liquid down the inner wall.
- 04
Awaken — swirl the dry ampoule for thirty seconds. The four-active cake dissolves into a clear pour within a minute.
- 05
Apply — dispense 3–5 drops onto your fingertips. Press gently onto face and neck in light, upward strokes. Pat until absorbed.
- 06
Rest — allow the serum to settle for two minutes before applying moisturiser or oil. Use within the hour of reconstitution.
Activated at the moment of use. Spent within the hour. The molecule never waits.

Niacinamide
The barrier and pigment modulator. A NAD⁺ precursor with 50 years of scientific data.
Before you buy.
Pour the diluent — gently pour the contents of the wet ampoule into the dry ampoule, running the liquid down the inner wall. Awaken — swirl the dry ampoule for thirty seconds. The four-active cake dissolves into a clear pour within a minute. Apply — dispense 3–5 drops onto your fingertips. Press gently onto face and neck in light, upward strokes. Pat until absorbed.
An 8-ampoule reconstitution kit — 4 lyophilised active ampoules and 4 pure diluent ampoules, totalling 4 sessions. Four flagship molecules co-lyophilised into a single luminous cake — HA, PDRN, GHK-Cu, Niacinamide.
36 months sealed · store 2–8°C · spent within the hour once reconstituted
Four pathways, one matrix — the systems-based stack. A foundational hydrator and a foundational vitamin, scaffolded by two regenerative actives, held dry until you ask for them. It's typically introduced the day after a gentle barrier reset or exfoliation — onto calmed, cleansed skin.
Yes. Once reconstituted, the serum is applied with clean fingertips as part of your evening skincare ritual. Dispense 3–5 drops and press gently onto cleansed face and neck. For topical cosmetic use only — not for injection.
