Healthy from deep within the skin filling the dermis with PN creates an environment for regeneration
Rejuran is a skin booster that delivers polynucleotide (PN) derived from salmon DNA into the dermis. It creates an environment in which damaged skin can recover on its own, helping to improve skin texture · elasticity · fine lines · pores together. DER AaN Cheongdam uses only genuine products.
Why Rejuran is different Three features of the PN skin booster
01 PN
PN ingredient that supports skin regeneration
The main ingredient, PN (polynucleotide), settles in the dermis and creates an environment in which damaged skin tissue can recover on its own. Rather than adding volume, this treatment helps build a healthier skin foundation.
02 Genuine
Treatment after authenticity check
Genuine Rejuran packaging carries the DOT® mark and an NFC authenticity label. We verify authenticity before opening the product.

These are the questions we are asked most often during consultations. Answers may vary depending on your individual skin condition.
How much does Rejuran cost?
The cost of Rejuran varies depending on the line (Rejuran · I · S · HB Plus), the volume and the number of sessions. After assessing your skin thickness and the areas of concern, we determine the line and number of sessions and explain them during the consultation.
How is Rejuran different from fillers and collagen boosters?
Fillers add volume with a gel, while collagen boosters use PLLA or PCL to stimulate collagen production and create volume. Rejuran is a skin booster that delivers salmon DNA-derived PN into the dermis to create an environment in which the skin recovers on its own, addressing skin texture, moisture-oil balance, elasticity and pores rather than volume.
When do Rejuran results appear and how long do they last?
Most people begin to notice changes in skin texture and oil–moisture balance from around two weeks after the procedure, with elasticity and regeneration effects building up over repeated sessions. How long the results last varies from person to person depending on skin condition and lifestyle, and treatment at regular intervals can help maintain them.
How many Rejuran sessions are needed, and at what intervals?
Treatment is usually divided into sessions at intervals of 2–4 weeks. Each session is designed with its own goal — the first for skin texture and moisture–oil balance, the second for firmness, and the third to fourth for regeneration — with intervals adjusted according to the skin's response.
Can Rejuran cause swelling or bruising as a side effect?
Injection marks and redness may last 1–2 days, and swelling or bruising a few days, but these usually settle naturally. The injected areas may feel slightly raised for a day or two, but this is generally absorbed. The procedure is performed after topical anesthetic cream, and aftercare instructions are provided.
How do Rejuran I, S and HB Plus differ?
We choose according to the area and the concern. Rejuran is for the skin texture and fine lines of the whole face, Rejuran I for thin areas such as around the eyes, Rejuran S for scarred areas, and HB Plus adds hyaluronic acid and lidocaine to PN and is used for fine lines at the outer corners of the eyes. Genuine products can be verified by the DOT marking on the carton and the NFC label.
Results and how long they last may differ depending on individual skin condition, and our medical staff will explain possible side effects during the consultation.
