Skin Booster Injections in Seoul: Hydration and Glass Skin
The short answer
Skin booster injections place tiny amounts of hydrating or regenerative ingredients, such as hyaluronic acid, PDRN or collagen stimulators, into the skin to improve hydration, texture and glow. In Gangnam a full-face session typically costs about ₩150,000–₩800,000, takes 20–40 minutes, and leaves small bumps for 1–3 days. Most people book 2–3 sessions four weeks apart, with results lasting about 4–9 months.

What skin boosters are
Unlike fillers, which add volume to reshape the face, skin boosters work on skin quality. They are injected in a fine grid of micro-droplets just beneath the surface, where they attract water, support repair or stimulate collagen. The goal is a smoother, plumper, more luminous complexion, often described in Korea as "glass skin".
Main types of booster
| Booster type | Main ingredient | Best for | Typical longevity |
|---|---|---|---|
| Hyaluronic acid booster | Lightly cross-linked or non-cross-linked HA | Deep hydration, fine lines | 4–6 months |
| Rejuran Healer | PDRN (salmon DNA fragments) | Repair, sensitivity, texture | 6–9 months after a course |
| Juvelook | PDLLA + HA | Collagen, pores, acne scars | 9–12 months after a course |
| Exosome or growth-factor boosters | Signalling molecules | Post-laser recovery, glow | Short; used in series |

Who is a good candidate?
- Dry, tight or dehydrated skin that does not improve with creams
- Dullness and uneven texture
- Fine lines on the cheeks, neck or around the eyes
- Enlarged pores and mild acne scarring
- People who want fresher skin without changing facial shape
Injection methods
Boosters can be injected by hand with a fine needle, by an injector gun that places precise micro-doses, or delivered with a microneedling device. Hand injection allows precise depth control; devices are faster and may feel more even. Some clinics also use needle-free systems for very gentle boosters.
What to expect
After cleansing, numbing cream is applied for 30–40 minutes. The doctor then injects across the face, sometimes including the neck. You will see tiny raised bumps at each point, like mosquito bites, which usually flatten within a day for HA and up to three days for PDRN or PDLLA products. Small bruises are possible. Most people return to normal activities the same day with light makeup the next morning.
Results and maintenance
Hydration boosters give a visible glow within a week. Collagen-stimulating boosters improve gradually over one to three months. A course of two to three sessions provides the best result, followed by maintenance every four to six months.
Typical prices in Gangnam
Booster pricing depends on the product, the volume in millilitres and the injection method. Hyaluronic acid boosters often start around ₩150,000–₩350,000 per session. Rejuran Healer commonly costs about ₩200,000–₩600,000 for the face, and Juvelook about ₩300,000–₩800,000. Exosome add-ons are usually priced separately. Many clinics sell three-session packages at a lower rate, and some combine a booster with a laser or lifting device for a single package price. Ask for the product name and volume in writing so you can compare quotes fairly.
Combining boosters with other treatments
Boosters improve skin quality, so they pair naturally with treatments that work on other layers. Many Gangnam patients have HIFU or radiofrequency lifting first and a booster afterwards, or alternate boosters with gentle laser toning for tone. Ask the doctor to plan the order and spacing so swelling from one treatment does not affect the next.
Planning boosters during a trip
Skin boosters fit well into short stays. Book them at least two days before an important event or flight photos, so bumps have settled. Ask the clinic which product brand and volume are used, whether it is hand-injected or device-assisted, and whether numbing and soothing care are included. Avoid alcohol, saunas and facial massage for 24–48 hours afterwards.
Safety notes
Boosters are considered low risk when given by trained doctors using approved products. Tell the clinic about allergies, especially to fish if considering PDRN, and avoid treatment if you have active infection or inflammation on the face.

Patient questions
Frequently asked questions
What is the difference between filler and a skin booster?
Fillers add volume and change shape; skin boosters improve hydration and skin quality without changing contours.
How long do the bumps last?
Usually 1 day for hyaluronic boosters and up to 2–3 days for PDRN or PDLLA products.
Which booster is best for me?
Hydration concerns suit HA boosters, sensitive or damaged skin suits PDRN, and pores or scars suit collagen boosters. A doctor can combine them.
Do skin boosters hurt?
With numbing cream most people feel light stings; PDRN can feel stronger than HA.
How often should I repeat boosters?
After an initial course, maintenance every 4–6 months is typical.
