Skin Booster Treatment in Seoul: Rejuran, Juvelook and More
The short answer
A skin booster in Seoul is a series of tiny injections that places hydrating or regenerative substances such as hyaluronic acid, polynucleotides (Rejuran) or PDLLA (Juvelook) into the dermis to improve skin quality rather than add volume. In Gangnam a full-face session typically costs about ₩200,000–₩800,000, takes 30–60 minutes, leaves small bumps for 1–3 days, and is repeated 2–3 times a month apart.

Boosters versus fillers
Fillers add volume to a specific point, such as a cheek or chin. Skin boosters are spread evenly across the face in many tiny deposits, so they do not change your shape. Instead, they target the quality of the skin itself: hydration, elasticity, fine lines, pore appearance and that dewy look Korean clinics call glass skin.
Boosters have become one of the most requested treatments in Seoul because they fit almost any age and combine well with lasers and lifting devices.
The main booster types
| Booster | Main ingredient | Best for | Onset |
|---|---|---|---|
| Rejuran | Polynucleotides (PN) | Repair, elasticity, fine texture | 2–4 weeks |
| Juvelook | PDLLA with hyaluronic acid | Gradual collagen, mild volume, pores | 4–8 weeks |
| Hyaluronic boosters | Non-crosslinked or lightly crosslinked HA | Deep hydration and glow | 1–2 weeks |
| Exosome treatments | Exosome-based solution, often with microneedling | Recovery, tone, sensitivity | Gradual |

How a session works
Numbing cream is applied for 30–40 minutes. The doctor then injects the product by hand or with an injector device that delivers many small, even deposits. Rejuran tends to sting more than hyaluronic boosters. Afterwards you may see small raised bumps that settle within a day or two, plus occasional pinpoint bruises. Most people return to normal activities the same day, wearing light makeup after 24 hours.
Cost in Seoul
Typical Gangnam prices are about ₩200,000–₩500,000 for a hyaluronic booster or standard Rejuran full face, and about ₩400,000–₩800,000 for Juvelook or premium combinations, with eye-area treatments priced separately. Packages of three sessions are common. Ask how many cc or syringes are included and whether the quote is for the full face or a single area.
Planning boosters around your trip
- Book your first session early in the trip so bumps settle before photos or events.
- A course is 2–3 sessions about a month apart; many visitors do one session per trip.
- Avoid alcohol, saunas and intense exercise for 24 hours.
- Combine with laser toning or lifting on the same day only if the doctor recommends it.
Who should be careful
Tell the doctor if you are pregnant or breastfeeding, have an active skin infection, autoimmune disease, or an allergy to fish products, since polynucleotides are derived from salmon DNA. People prone to cold sores may need antiviral medication beforehand.
Choosing a clinic
Ask which brand is used and whether you can see the sealed product, how much is injected, and whether a doctor performs the injections. A clinic should explain why a particular booster suits your skin rather than offering the most expensive one by default. For clinic options, see our list of skin booster clinics in Apgujeong.

Patient questions
Frequently asked questions
Which skin booster is best for me?
It depends on your goal: hyaluronic boosters for hydration, Rejuran for repair and elasticity, Juvelook for gradual collagen and pore improvement.
Do skin boosters hurt?
Numbing cream makes it manageable, though Rejuran typically stings more than hyaluronic boosters.
How long until I see results?
Hydration boosters show within 1–2 weeks; collagen-type boosters build over 4–8 weeks.
Can I fly after a skin booster?
Yes, usually the next day. Bumps or minor bruising do not prevent flying.
How often should I repeat it?
After an initial course of 2–3 sessions, many people maintain every 4–6 months.
