JUNSUI SaiseiWhere the surface returns to itself.
Saisei holds salmon-derived PDRN scaffolded by centella fractions, niacinamide and panthenol — built for the days after a peel, a laser, a needling session. Inspired by kintsugi: not erasing what was, but honouring the recovery.
PDRN's wound-healing literature is strong; the aesthetic data is rapidly maturing. Saisei supports the skin's repair environment — it does not rewrite cells.

How to use.
- 01
Best the day after a gentle barrier reset — light needling, a peel, a laser session.
- 02
Deliver with a tri-pin cap, dermastamp or microneedling pen (sold separately) so the molecule reaches the layer that asked for it.
- 03
For practitioners: a 1.0mm tri-pin places PDRN into a scar bed with precision.
- 04
One session every six weeks for three or four turns, then as the skin asks.
- 05
Always sterile — clean hands, single-use caps, calm workspace.
Ampoules ship as serum only — sealed medical glass, nothing more. The sterile tri-pin 34G caps and refill boxes are sold separately on theMesotherapy page.
The JUNSUI tri-pin cartridge.
The recommended companion to JUNSUI Saisei — three medical-grade pins, copper-tinted housing, and a gold luer base that mounts directly to the ampoule. Sold separately as a sterile ten-cap refill box.
