What Rejuran is
Rejuran is an injectable skin treatment developed in Korea. Its main ingredient is polynucleotide (PN), a substance derived from purified salmon DNA fragments. Rather than adding volume like a filler, Rejuran is injected in small amounts into the skin to support the skin's own repair processes. It is often grouped with "skin boosters", treatments that focus on skin quality rather than shape.
Many visitors to Busan ask about Rejuran because it is closely associated with the Korean approach to healthy-looking skin. You can find more background on our Rejuran page.
Possible skin benefits
People usually consider Rejuran for concerns related to skin quality. Commonly discussed goals include:
- Texture.
Skin that feels rough or uneven.
- Fine lines.
Especially early lines on the cheeks and around the eyes.
- Elasticity.
Skin that looks tired or has lost some bounce.
- Skin resilience.
Skin that seems thin or easily irritated.
- Support for scarring.
Sometimes discussed as part of a wider plan for mild acne scarring.
Evidence for polynucleotide treatments is still developing, and results vary between individuals. Changes are usually gradual and subtle, and many treatment plans involve more than one session spaced several weeks apart. A doctor will advise whether Rejuran suits your skin and how many sessions might be reasonable.

What happens during the treatment
A typical Rejuran session follows a straightforward sequence:
- Consultation.
The doctor examines your skin and confirms suitability and volume.
- Cleansing and numbing.
A numbing cream is usually applied to make the injections more comfortable.
- Injection.
Small amounts are placed across the treatment area with a fine needle.
- Calming.
The skin is cleaned and soothed before you leave.
Rejuran injections are often described as more noticeable than some other skin boosters, because the product is placed in many small points. Comfort varies from person to person.
Healing time and aftercare
Rejuran usually leaves small raised bumps at the injection points. These are expected and typically flatten within a day or so, though it can take longer for some people. Other common, short-lived effects include:
- Redness.
Often fades within hours to a day.
- Mild swelling.
Usually settles in a few days.
- Bruising.
Possible at some injection points and may take several days to fade.
General aftercare advice often includes keeping the skin clean, avoiding heavy makeup on the day of treatment, avoiding saunas, intense exercise and alcohol for a short period, and using sun protection. Your doctor will give specific instructions. If you notice increasing pain, spreading redness, warmth or anything unusual, contact the clinic or a doctor promptly. Pregnant or breastfeeding patients, and anyone with allergies to fish-derived products, should discuss this with a doctor before treatment.
Planning Rejuran around a trip
Because the bumps usually settle quickly, many travellers schedule Rejuran early in their stay rather than the day before an important event or photo session. If you are interested in a series, ask the doctor how sessions might be spaced and whether a follow-up could be done on a later trip or at home.
Rejuran is one of several skin booster options. Our skin boosters page
explains how it compares with other options listed at the clinic.
