Rejuran Healer
Skin repair from within, using salmon-derived PN

In short
Rejuran Healer injects PN (polynucleotide) derived from salmon DNA into the skin to switch on the skin's own repair capacity. Lienjang frames it for skin in the 20s to 40s, from stress-damaged and dry skin through to fine lines and reduced elasticity.
- Session time
- About 30 minutes including numbing
- Downtime
- Injection bumps for 12–24 hours
- Result & repeat
- Starter course of 3–4, spaced 2–4 weeks
How it works
The PN is cut into segments chosen for biocompatibility. Injected into the skin it interacts with a range of proteins from the epidermis down, helping rebalance oil and water, repair damaged cells and improve elasticity.
What the clinic highlights
- The clinic states it uses authentic product at standard dosing.
- Lienjang lists three core effects: oil–water balance, repair of damaged skin cells and better elasticity.
- Suits skin recovering from lasers or acne that needs to rebuild.

Who it suits
- Late 20s with stress- and sleep-depleted skin
- 30s with imbalanced hydration and early fine lines
- 40s with slower repair, rough texture and dullness
Aftercare
- No makeup on day one and avoid touching the face.
- Avoid sauna, heavy exercise and alcohol for two to three days.
FAQ
How long do the bumps last?
Most settle within 12–24 hours; thin skin may still show them on day two.
Can I have it if I'm allergic to fish?
Always tell the doctor: the raw material comes from salmon DNA, and the risk is assessed individually.
How many sessions before it clearly shows?
The clinic recommends starting with three to four, since the repair effect accumulates per round.
