What is Rejuran Healer?

Rejuran Healer is one of Korea's best-known skin boosters. It is made by Pharma Research, a Korean company, from polynucleotides (PN): highly purified DNA fragments extracted from salmon. PN works as a scaffold and signal for the skin's own repair processes. Rather than filling or plumping, Rejuran improves the quality of the skin itself, making it thicker, calmer, smoother and more resilient. Read more in is Rejuran made from salmon.

It is the booster many Korean dermatologists reach for when skin is sensitized, thin or recovering from laser or acne. The Rejuran family also includes a finer formula for the eye area and a version used for scars; your doctor chooses the one that fits your skin. You will find it with our other skin quality treatments in the treatment menu.

How Rejuran Healer works

Repair: PN supports fibroblasts, the cells that produce collagen, helping damaged skin recover.
Thickness and elasticity: over a series, the dermis becomes denser and more elastic.
Calming: PN has anti-inflammatory effects, so it can help redness and sensitive skin.
Texture: pores, fine lines and shallow acne scars gradually look softer.

Who is a good candidate?

Dull, tired or thin skin that has lost bounce
Enlarged pores, rough texture or shallow acne scars
Sensitive or reddened skin, or skin recovering from laser
People who want better skin quality without adding volume

Rejuran is also a common add-on after laser or microneedling, because it supports recovery. It will not lift sagging skin or add volume to hollows; for those, your doctor may suggest a lifting device or a collagen stimulator. For the delicate under-eye area, a finer formula, Rejuran Eye, is used instead.

Your session at Dernia, step by step

Consultation in English with a licensed medical doctor, who reviews your skin and allergies.
Numbing with topical anesthetic cream for 30–40 minutes.
Injection: many tiny droplets placed evenly in the upper dermis, by hand or with an injector device.
Soothing with a calming mask and aftercare advice.

Rejuran has a reputation for stinging more than other boosters. Good numbing and technique make a real difference; see does Rejuran hurt.

Downtime and aftercare

Small raised bumps appear where each droplet was placed and usually flatten within one to three days. Pinpoint bruises are possible. Most people wear light makeup the next day. For 24 hours, avoid saunas, alcohol and intense exercise, and skip exfoliating acids and retinoids for a few days. Do not press or massage the bumps; they flatten on their own as the product spreads. A gentle cleanser, a plain moisturizer and sunscreen are all your skin needs.

Results: what to expect and when

Skin often looks more hydrated within a week or two. Firmer, smoother, calmer skin builds over the series, with the clearest change around four to eight weeks after the third session. Maintenance every six months or so helps keep it. See the Rejuran Healer results timeline.

Rejuran Healer vs other skin boosters

Rejuran repairs and thickens. Juvelook stimulates collagen with PDLLA and is often chosen for scars and pores: see Rejuran vs Juvelook. Profhilo focuses on hydration and bounce: see Rejuran vs Profhilo. Exosome therapy is a topical, needle-light option: see Rejuran vs exosomes.

Planning Rejuran around a trip to Seoul

One session already improves skin quality, so it suits a short stay. If you are in Seoul for two to four weeks, you may fit in two sessions; otherwise, many visitors have one session per trip and continue the series on later visits or with a doctor at home. Allow a day or two for bumps to settle before photos or flights. Rejuran pairs well with skin Botox in the Glass Skin Package. Book a consultation and your doctor will plan your sessions.

Safety: who should avoid or delay it

Rejuran is not suitable during pregnancy or breastfeeding, with active infection or a flare of acne in the area, or if you are allergic to fish or salmon. Tell your doctor about bleeding disorders, blood thinners and autoimmune conditions. At Dernia, Rejuran is injected by licensed medical doctors.

Is Rejuran really made from salmon?

Yes. Rejuran's polynucleotides are purified DNA fragments derived from salmon. If you have a fish allergy, tell your doctor before treatment.

Does Rejuran Healer hurt?

It stings more than most skin boosters because of the many small injections. Numbing cream for 30–40 minutes keeps it manageable for most people.

How many Rejuran sessions do I need?

Most people see the best change after three sessions spaced two to four weeks apart, followed by maintenance every six months or so.

When will I see Rejuran results?

Hydration and glow can appear within one to two weeks. Texture and firmness build over the series, with the clearest change one to two months after the last session.

Is there downtime after Rejuran?

Small bumps last one to three days, with occasional pinpoint bruises. Most people return to normal plans the same day and wear makeup the next day.
