How PN works
What happens in your skin after a Rejuran injection.
Rejuran does not fill a line like a filler. It supports the skin's own repair. Here is the order of events, step by step.
Illustration only. Layers are drawn larger than real scale. Results vary from person to person.
Three types
Rejuran Healer, HB or Eye: which one fits your skin.
All three are PN skin boosters. The difference is what is added and where it goes. Your doctor picks the type at your consultation.
Rejuran HB
Adds hyaluronic acid for extra hydration. Lidocaine in the mix makes the injection more comfortable.
Rejuran I (Eye)
Made for the thin, delicate skin under the eyes. Targets fine lines, thin skin and dark circles.

Compare boosters
Rejuran or another skin booster?
HERA offers several skin boosters. Each one works differently. Your doctor starts with an EVE V MUSE skin scan, then matches the booster to what your skin needs.
Skin scan first
The EVE V MUSE scan looks at your skin before any booster is chosen. The result guides whether Rejuran or another booster fits.

For international visitors
Rejuran Korea trip: plan the course around your visit.
Rejuran works as several sessions a few weeks apart. Most visitors are in Seoul for a shorter time. Here is how to plan.
Have the first session early in your trip
Small bumps usually settle within a few days. An early session leaves time for that before you fly home.
Send your dates on WhatsApp
Tell us when you land and leave. We ask the doctor how to space your sessions around those dates.
Plan the next sessions
If you visit Korea again, ask us how later sessions and maintenance fit those dates.

FAQ
Questions about Rejuran in Korea
Short answers from HERA. Ask us anything else on WhatsApp.
What is Rejuran made of?
Rejuran's key ingredient is polynucleotide (PN), a regenerative substance extracted and highly purified from salmon DNA that helps stimulate the skin's own repair and renewal.
What is the difference between Rejuran, Rejuran HB and Rejuran I?
Standard Rejuran (Healer) focuses on overall skin regeneration. Rejuran HB adds hyaluronic acid for extra hydration and a more comfortable injection, and Rejuran I (Eye) is specially formulated for the thin, delicate skin around the eyes.
How many sessions will I need?
A course of several sessions spaced a few weeks apart is typically recommended for the best results, followed by periodic maintenance. Your doctor will tailor the plan to your skin.
Does the injection hurt?
Topical numbing cream is applied first, and formulations such as Rejuran HB contain lidocaine to further reduce discomfort. Most patients find it very tolerable.
When will I see results and how long do they last?
Skin usually looks more hydrated and radiant within a couple of weeks, with firmness and texture continuing to improve over the treatment course. Maintenance sessions help sustain the results over time.
Can I get Rejuran during a short trip to Korea?
Yes. One session takes about 20–30 minutes. Small bumps and redness generally settle within a few days. Rejuran works as a course of several sessions a few weeks apart, so send us your travel dates on WhatsApp and we plan the spacing with the doctor.
I have a fish allergy. Can I have Rejuran?
Rejuran's PN is purified from salmon DNA. If you have any allergy history, a doctor consultation is required before treatment. Tell us about your allergy on WhatsApp before you book.
