Rejuran Healer in Seoul: PDRN Skin Regeneration
The short answer
Rejuran Healer is a Korean skin booster made from PDRN (polynucleotides derived from salmon DNA) that supports skin repair, improving elasticity, texture, fine lines and sensitivity. In Gangnam a full-face session typically costs about ₩200,000–₩600,000, takes 30–45 minutes with numbing, and leaves small bumps for 1–3 days. Most people book 3 sessions four weeks apart, with results lasting 6–9 months.

What Rejuran Healer does
Rejuran Healer is one of the best-known Korean skin treatments and a staple of the glass-skin trend. Its active ingredient, polynucleotides (often called PDRN), comes from purified salmon DNA. In the skin, these fragments are thought to support cell repair, reduce inflammation and encourage collagen production. Rather than filling or plumping, Rejuran works on the underlying health of the skin.
Patients often describe the result as skin that is calmer, firmer, smoother and more resilient, rather than visibly "done".

Tell the clinic if you have a fish or salmon allergy, as Rejuran may not be suitable.
The treatment process
Numbing cream is applied for 30–40 minutes because Rejuran is known for stinging more than hyaluronic boosters. The doctor injects many tiny droplets across the face with a fine needle, an injector gun, or both. Each droplet leaves a small raised bump. A calming mask or LED usually follows. Rejuran HB, which contains lidocaine, is a more comfortable option for people sensitive to pain.
Recovery
Bumps typically flatten within 24 hours for most of the face but can linger up to three days, especially with Rejuran S or thinner skin. Small bruises can take up to a week. Avoid makeup on the treatment day, and skip saunas, alcohol and intense exercise for a day or two.
Results and sessions
Some improvement in glow is visible within a week, and more noticeable changes in elasticity and texture appear after the second and third sessions. A course of three sessions four weeks apart is standard, followed by maintenance every six months or so. Combining Rejuran with lifting devices or lasers is common in Gangnam, as each targets a different layer.
Typical prices and what affects them
In Gangnam, a full-face Rejuran Healer session commonly costs about ₩200,000–₩600,000. The price depends on the product version, the volume used (often 2 cc for the face), the injection method and whether numbing, soothing care or LED are included. Rejuran i for the eyes and Rejuran S for scars are often priced separately, and three-session packages usually offer a lower per-session rate. Hand injection by a doctor may cost more than device delivery but allows more precise placement in delicate areas.
Booking Rejuran as a visitor
Rejuran fits into short trips but plan it at least two days before photos or flights. If you can only manage one session, ask the doctor whether a higher dose or a combination with another booster would be appropriate. Confirm the product (Healer, HB, i or S), the volume in cc and the injection method. For more clinic options, browse Rejuran Healer clinics in Apgujeong and our skin booster overview.
Supporting your results at home
Gentle skincare helps Rejuran work. Use a mild cleanser, a barrier-supporting moisturiser and daily sunscreen, and pause strong exfoliants for a few days after each session. Good sleep and hydration also make a visible difference to how quickly skin recovers.
