Also known as: Rejuran Healer, salmon DNA injection, PN skin booster
Rejuran uses PN (polynucleotides) derived from salmon DNA to support the skin’s own recovery environment. It is injected finely into the dermis. There are versions for the full face (Healer), with added lidocaine and HA (HB), and for the thin eye area (Rejuran i). We record the product and volume for you.

Overview
What is Rejuran?
Rejuran doesn’t fill volume like a filler. It is used when skin has become thin, sensitive or tired, to help it recover and feel denser over a series of sessions.
Small bumps appear right after injection and usually settle in 1–2 days, so we plan it around your schedule.
How it works
How it works

Doctor’s note
Rejuran is less about dramatic change and more about skin that feels calmer and firmer. Most people notice the difference after a few sessions.

Questions
Rejuran FAQ
Healer vs HB?
HB adds lidocaine and HA for comfort; we choose based on your skin and schedule.
Can I do it before flying home?
Bumps can last 1–2 days, so we suggest earlier in your stay.
How many sessions?
Usually 3, 2–4 weeks apart.
I’m allergic to fish.
Then Rejuran isn’t suitable; we’ll suggest another booster.
Can it be combined with Potenza?
Yes — often in our K-Glass Skin program.
