Skin Booster Injections in Korea: Rejuran, Juvelook, and More — Complete Guide 2026
If you have been researching Korean skincare treatments, you have almost certainly come across the term "skin booster" (스킨부스터) or "water glow injection" (물광주사). These injectable treatments are among the most sought-after procedures in Seoul's dermatology clinics, promising deeply hydrated, luminous skin from the inside out. Korea is where many of these products were developed, and the country remains the global epicenter for skin booster innovation and affordability.
In this guide, we break down the most popular skin booster types available in Korea in 2026, compare prices with international markets, and recommend clinics in Seoul where you can get treated — even if you do not speak Korean.
What Are Skin Booster Injections?
Skin boosters are micro-injections delivered into the dermal layer of the skin, approximately 1mm deep. Unlike traditional dermal fillers that add volume to specific areas, skin boosters work by flooding the dermis with active ingredients — hyaluronic acid, polynucleotides, collagen stimulators, or growth factors — to improve overall skin quality.
The results include:
- Deep hydration that topical products cannot achieve
- Improved skin texture and reduced pore size
- Increased collagen and elastin production for firmer skin
- Brighter, more even skin tone
- Reduction of fine lines and superficial wrinkles
According to Korean dermatology platform Goodoc, 70% of patients notice results immediately after treatment, while the remaining 30% see visible improvement within one week.
Types of Skin Boosters Available in Korea
Korea offers the widest range of skin booster products in the world. Here are the four major categories you need to know about.
Rejuran (리쥬란) — Salmon DNA Skin Healer
Rejuran is arguably Korea's most iconic skin booster. Its active ingredient is polynucleotides (PN) derived from salmon DNA, which promotes cellular regeneration and repairs damaged skin at the molecular level.
- Best for: Dry, sensitive, or damaged skin; improving skin barrier function; overall anti-aging
- Key benefits: Skin regeneration, deep hydration, tone improvement, reduced inflammation
- Effect onset: Relatively fast — noticeable within 1-2 weeks
- Duration: 6-9 months
- Sessions needed: 3 sessions at 2-3 week intervals for optimal results
- Price in Korea: ₩120,000-₩350,000 ($90-$270 USD) per session
Rejuran also comes in specialized formulations including Rejuran i (for the under-eye area) and Rejuran HB (with added hyaluronic acid for extra hydration).
Juvelook (쥬베룩) — Collagen-Stimulating Powerhouse
Juvelook has surged in popularity since 2024, combining PDLLA (poly-D,L-lactic acid) with non-crosslinked hyaluronic acid. While the HA provides immediate hydration, the PDLLA gradually stimulates your body's own collagen production over months.
- Best for: Skin laxity, acne scarring, enlarged pores, signs of aging (especially 35+)
- Key benefits: Collagen stimulation, improved firmness, volume restoration, scar improvement
- Effect onset: Gradual — full results at 4-8 weeks as collagen builds
- Duration: 12-18 months (longest-lasting among skin boosters)
- Sessions needed: 3 sessions at 2-4 week intervals
- Price in Korea: ₩100,000-₩500,000 ($75-$385 USD) per session
The newer Juvelook Volume formulation contains higher PDLLA concentration for more pronounced lifting and volumizing effects.
Chanel Injection / NCTF 135HA (샤넬주사) — The Multi-Vitamin Cocktail
The "Chanel injection" — officially Filorga NCTF 135HA — earned its luxury nickname from the premium, luminous glow it delivers. This is a complex cocktail containing 55 active ingredients: 12 vitamins, 23 amino acids, 6 coenzymes, 5 nucleic acids, 6 minerals, antioxidants, and hyaluronic acid.
- Best for: Dull, tired-looking skin; overall skin revitalization; pre-event glow
- Key benefits: Comprehensive skin nourishment, brightening, fine line reduction, improved radiance
- Effect onset: Immediate glow with progressive improvement
- Duration: 2-3 months per session
- Sessions needed: 3-5 sessions at 2-4 week intervals
- Price in Korea: ₩200,000-₩350,000 ($155-$270 USD) per session
Exosome Skin Boosters (엑소좀) — Stem Cell Technology
Exosome boosters represent the cutting edge of Korean skin rejuvenation. Exosomes are nano-sized vesicles derived from stem cells that carry growth factors, proteins, and genetic material to stimulate cellular repair and regeneration.
- Best for: Advanced anti-aging, post-procedure healing, comprehensive skin renewal
- Key benefits: Cellular-level regeneration, collagen synthesis, accelerated healing, improved elasticity
- Effect onset: Gradual — 2-4 weeks for visible changes
- Duration: 3-6 months
- Sessions needed: 3-5 sessions
- Price in Korea: ₩190,000-₩500,000 ($145-$385 USD) per session
The most popular exosome product in Korea is ASCE+ (ExoSCRT technology), used at clinics across Gangnam and Myeongdong.

Korea vs. International Price Comparison
One of the biggest reasons international visitors travel to Seoul for skin boosters is the dramatic cost savings. Korean clinics benefit from high competition, wholesale product purchasing, and specialized expertise that keeps prices far below global averages.
| Treatment | Seoul, Korea (KRW) | Seoul, Korea (USD) | United States (USD) | Savings |
|---|---|---|---|---|
| Rejuran Healer (per session) | ₩120,000-₩350,000 | $90-$270 | $400-$800+ | 55-70% |

Prices as of February 2026. Exchange rate used: ₩1,300 = $1 USD. Actual costs vary by clinic, treatment area, and product volume. Contact clinics directly for current pricing.
Note that Rejuran is not yet FDA-approved in the United States, making Korea one of the few places where international visitors can access this popular treatment from experienced practitioners. Many Seoul clinics also offer package deals for 3-5 sessions, reducing per-session costs by 15-30%. Booking platforms like Gangnam Unni (강남언니) and Yeoshin Ticket (여신티켓) frequently list promotional prices.
How the Procedure Works
Before Treatment
- Consultation: The dermatologist examines your skin and recommends the most suitable booster type
- Cleansing: Your face is thoroughly cleansed and disinfected
- Numbing: A topical anesthetic cream is applied for 20-30 minutes
During Treatment
- The skin booster is loaded into a multi-needle injector (known as a "nappage" device or Vital Injector) or administered via individual micro-injections
- The product is injected into the dermal layer at approximately 1mm depth
- The injector delivers uniform micro-droplets across the treatment area
- The entire injection process takes approximately 15-30 minutes
After Treatment
- The clinic may apply a soothing mask or LED therapy
- You can typically return to normal activities the same day
- Total clinic visit time: approximately 60-90 minutes
Recovery and Side Effects
Skin booster injections have minimal downtime compared to more invasive procedures. Here is what to expect:
Immediately after treatment:
- Small bumps (papules) at injection sites — these flatten within 24-48 hours
- Mild redness and swelling
- Possible light bruising at some injection points
Recovery timeline:
- Day 1-2: Bumps and redness subside; avoid heavy makeup
- Day 3-5: Avoid saunas, intense exercise, and swimming
- Day 7: Skin begins to look noticeably more hydrated and radiant
- Week 2-4: Full results become apparent (varies by product type)
Side effects to watch for:
- Bruising (common, resolves in 3-7 days)
- Mild swelling (1-3 days)
- Temporary tenderness at injection sites
- In rare cases, infection or allergic reaction — seek medical attention if symptoms persist
It is important to note that Korean health authorities have flagged that some skin booster products are classified as cosmetics rather than medical devices. Always choose a reputable, licensed dermatology clinic to ensure product safety and proper administration.

Frequently Asked Questions
Q: Which skin booster is best for first-time visitors to Korea? A: Rejuran is the most popular choice for first-timers because it offers broad benefits — hydration, regeneration, and tone improvement — with fast-acting results and minimal downtime. It is also uniquely Korean, making it a treatment you cannot easily get elsewhere.
Q: Can I combine different skin boosters in one visit? A: Yes, many Korean dermatologists recommend combination protocols. A common approach is pairing Rejuran (for skin repair) with Juvelook (for collagen stimulation) in the same session or across consecutive visits. Some clinics like ID Skin Clinic offer pre-designed combination packages at discounted rates.
Q: How many sessions do I need if I am only visiting Seoul for a short trip? A: While three sessions spaced 2-4 weeks apart is ideal, even a single session will provide noticeable improvement. Many medical tourists get one treatment during a week-long stay. You can continue with follow-up sessions at a clinic in your home country or on a return visit.
Q: Is the procedure painful? A: Most patients describe the sensation as mild discomfort rather than pain. Clinics apply topical numbing cream for 20-30 minutes before the injections, which significantly reduces sensitivity. The multi-needle injector used in Korea is designed for even distribution with minimal pain.
Q: How do I book an appointment at a Seoul clinic as a foreigner? A: Many clinics accept bookings through their English websites, Instagram DMs, KakaoTalk, or email. Platforms like Gangnam Unni (강남언니) and Modoodoc (모두닥) also allow you to compare prices and book online. Confirm English-speaking staff availability before your visit.
Q: Are skin boosters safe? A: When administered by a licensed dermatologist using approved products, skin boosters have a strong safety profile. However, Korean health authorities have noted that some skin booster products are classified as cosmetics rather than medical devices. To minimize risk, choose established clinics with board-certified dermatologists and verified product sourcing. If you have a known fish allergy, inform your doctor before receiving Rejuran, as it is derived from salmon DNA (though the polynucleotide is highly purified with very low allergy risk).
Conclusion
Korea remains the undisputed leader in skin booster innovation, offering treatments like Rejuran and Juvelook that are difficult or impossible to access in many other countries. With prices 50-70% lower than the United States and some of the most experienced dermatologists in the world, Seoul is the ideal destination for anyone looking to transform their skin quality from the inside out.
Whether you are dealing with dehydration, early signs of aging, acne scarring, or simply want that coveted Korean "glass skin" glow, there is a skin booster tailored to your needs. Book a consultation at one of the clinics listed above, and take the first step toward radiant, rejuvenated skin.
