Rejuran Healer vs exosome therapy at a glance

Both are popular in Korea for skin repair, calmer redness and better texture, and both are often discussed as regenerative treatments. They are delivered very differently. Rejuran Healer is injected into the dermis, while exosome therapy applies a serum to the skin straight after microneedling or laser so it can reach deeper through tiny channels.

Technology	Polynucleotides (PN) from salmon DNA (Pharma Research)	Exosome serum applied with microneedling or laser

How Rejuran Healer works

Rejuran Healer, made by Pharma Research in Korea, contains purified polynucleotides from salmon DNA. Injected across the face, PN supports the skin's natural repair processes, improves hydration and helps calm inflammation. Over a series, skin tends to look thicker, more elastic and less reactive. Polynucleotide-based boosters have been used in Korean dermatology for many years, so doctors have a good sense of what to expect.

How exosome therapy works

Exosomes are tiny vesicles that cells release to carry signals, including proteins and other molecules, to neighboring cells. Exosome serums for skin are produced from cultured cells or plant sources and are designed to support repair and calm inflammation. At Dernia, the serum is applied immediately after microneedling or laser so it can pass through the fresh microchannels. Research on exosomes in dermatology is promising but still emerging, and products vary in source and concentration, so we describe expected benefits conservatively.

Choose Rejuran Healer if…

You want an injected booster with a long track record in Korea
Your skin is thin, fragile or easily irritated
Fine lines and enlarged pores are part of your concern
You want results that build visibly over three sessions

Choose exosome therapy if…

You have post-acne marks, redness or rough texture
You prefer microneedling with a serum to multiple injections
You are having laser or microneedling and want to support recovery
You want a lower per-session cost and can complete a series

Can you combine them?

Yes. They work in complementary ways, and many plans use both: Rejuran injected for skin strength, and exosome serum applied with microneedling or after laser to support healing. Your doctor may alternate them across visits about two to four weeks apart. Exosome therapy is also part of our Acne Reset Package(from ₩249,000).

How our doctors decide

Your doctor examines your skin's thickness, sensitivity, redness and texture, and asks what other treatments you are planning. Thin or reactive skin with fine lines points to Rejuran. Marks, redness and texture, especially alongside laser or microneedling, point to exosome therapy. If you are already planning laser or RF microneedling during your stay, adding exosome serum to that session is an efficient way to support recovery without an extra appointment.

Rejuran is not injected during pregnancy or breastfeeding, over active infection, or without review if you take blood thinners or have a fish allergy. Microneedling is postponed during active acne infection or cold sores and after recent isotretinoin use. See typical outcomes on the exosome therapy results page, browse more comparisons, or book a consultation and a licensed doctor will recommend the repair plan that suits your skin.

Are exosomes better than Rejuran?

They are different tools. Rejuran is an injected polynucleotide booster with a long track record in Korea, while exosome serum is applied with microneedling or laser to support recovery. Exosome research is promising but still developing, so your doctor will explain realistic expectations.

Are exosomes injected?

At Dernia, exosome serum is applied to the skin immediately after microneedling or laser, so it can pass through the fresh microchannels. It is not injected as a standalone product.

Which is better for post-acne redness?

Exosome therapy with microneedling is often chosen for post-acne marks and texture, while Rejuran helps calm and strengthen reactive skin. Persistent red marks may also benefit from a vascular laser.

How much downtime should I expect?

Rejuran leaves small bumps for one to three days. Exosome therapy with microneedling usually causes redness for one to two days. Both fit easily into a trip.

Can I have both in one visit?

Sometimes. Your doctor may inject Rejuran and apply exosome serum with microneedling in one session, or alternate them. The plan depends on your skin's sensitivity and goals.
