Quick answer: Dermal fillers are injectable gels that restore volume, smooth folds and reshape features such as the lips, chin and nose. Most fillers in Korea are hyaluronic acid (HA), which lasts roughly 6 to 18 months depending on the product and area and can be dissolved if needed. Serious complications are rare but real, so the injector's experience matters more than price.
Types of fillers
- Hyaluronic acid (HA): the most common; immediate results, reversible with hyaluronidase.
- Collagen stimulators (PLLA, PCL, CaHA): build volume gradually over weeks and last longer, but cannot be dissolved like HA.
- Skin boosters: very thin HA or polynucleotides for hydration rather than volume.
Popular treatment areas
- Lips and lip borders.
- Chin projection and jawline definition.
- Nasolabial folds and marionette lines.
- Forehead and temples for a rounder profile.
- Non-surgical nose shaping.
- Under-eye hollows (advanced technique).
How long fillers last
- Lips: about 6 to 9 months.
- Nasolabial folds: about 9 to 12 months.
- Chin and jaw: about 12 to 18 months.
Metabolism, product density and movement in the area affect duration.
Risks
- Common: swelling, bruising, tenderness for a few days.
- Less common: lumps, asymmetry, migration over time.
- Rare but serious: vascular occlusion, where filler blocks a blood vessel; early signs include severe pain, blanching or dusky skin. This is a medical emergency requiring immediate treatment.
Safety checklist
- Ask for the product name and volume (cc) and see the sealed box.
- Confirm the doctor performs the injection.
- Ask whether hyaluronidase is kept on site.
- Avoid very cheap offers of unknown products.
Aftercare
- Avoid pressing or massaging unless instructed.
- Skip saunas, alcohol and heavy exercise for 24 to 48 hours.
- Sleep on your back the first night.
Hyaluronic acid filler brands in Korea
Korean clinics use a wide range of approved hyaluronic acid fillers, including Korean brands and imported brands such as Juvederm and Restylane. Products differ in particle size, firmness and how much they spread. Softer fillers suit lips and fine lines, while firmer, more cohesive fillers suit the chin, nose and jawline where structure is needed. A good injector chooses the product by area rather than using one filler for everything.
Typical volumes by area
- Lips: 0.5 to 1 cc.
- Chin: 1 to 3 cc.
- Nasolabial folds: about 1 cc per side.
- Temples or forehead: 1 to 4 cc depending on hollowness.
- Nose: often less than 1 cc.
Starting conservatively and adding more later gives a more natural result and lowers risk.
Cost in Busan
Dermal filler in Busan typically costs about ₩100,000 to ₩500,000 per 1 cc syringe in 2026, depending on the brand. Collagen stimulators such as Sculptra cost about ₩400,000 to ₩1,200,000 per vial.
Needle vs cannula
Fillers can be injected with a fine needle for precise placement or with a blunt-tipped cannula that slides under the skin through a small entry point. Cannulas may reduce bruising and lower the risk of entering a blood vessel in some areas, while needles allow precise detail work, such as lip borders.
Recognising a vascular emergency
Rarely, filler can block a blood vessel. Warning signs include severe pain, skin turning white, blue or mottled, or vision changes. This needs immediate treatment with hyaluronidase at the clinic or emergency care. Choosing an experienced doctor and staying nearby for 24 hours after filler are important precautions.
Planning fillers during a trip to Busan
Swelling and bruising usually settle within a few days, but lips can stay swollen for up to a week. Most single areas are done in one session, with an optional touch-up after two weeks. Most international visitors stay in Seomyeon, the city's largest clinic district and a central subway hub, or in Haeundae and Centum City near the beach. Seomyeon is about 35 minutes from Gimhae International Airport by light rail and subway and about 12 minutes from Busan Station (KTX) on Line 1, while Haeundae is about 30 to 40 minutes further east on Line 2. Book your consultation before you arrive, share your travel dates with the clinic, and leave at least one buffer day before your flight in case you want a follow-up check.
Questions to ask at your consultation
- Which filler brand and how many cc will you use for each area?
- Do you use a needle or cannula for this area?
- Is hyaluronidase available on site if needed?
- Is the clinic registered with HIRA, and who will perform the treatment?
- Does the written quote include VAT, numbing cream and any follow-up visit?
- How can I contact the clinic with questions after I return home?
How to choose a clinic for dermal fillers in Busan
Busan has roughly 1,000 registered clinics across dermatology, plastic surgery and other specialties, so it is worth comparing a few before you book. Start by checking that the clinic is listed with Korea's Health Insurance Review and Assessment Service (HIRA), then look at the doctor's specialty and experience with dermal fillers. In Korea, a clinic name that includes "Dermatology" (피부과) or "Plastic Surgery" (성형외과) indicates the director is a board-certified specialist in that field. During consultation, a good clinic will explain realistic results, side effects and alternatives, give you a written quote, and never pressure you into same-day packages. Read recent patient reviews with a critical eye, and favour clinics that provide English aftercare instructions and a clear way to contact them after you leave Korea.
