Quick answer:
Dermal fillers in Busan are mostly hyaluronic acid (HA) gels, with collagen-stimulating options such as calcium hydroxylapatite and poly-L-lactic acid also available. HA fillers commonly last around six to eighteen months depending on product and area. Safety depends on an MFDS-approved product, an experienced doctor, and a clear plan for rare vascular complications.
The Main Types of Fillers
Hyaluronic acid (HA) fillers
HA is a sugar molecule naturally found in skin. HA fillers are cross-linked to make them last longer, and different products vary in firmness, cohesiveness and how they spread. Common brands include Juvederm, Restylane and Belotero, along with Korean products such as Yvoire, Neuramis and Chaeum. A key advantage is that HA can usually be dissolved with an enzyme called hyaluronidase if the result is unwanted or a complication occurs.
Calcium hydroxylapatite (CaHA)
Products such as Radiesse provide immediate volume and stimulate collagen. They are often used for deeper structural support, such as the jawline. They cannot be dissolved with hyaluronidase, so placement experience is particularly important.
Poly-L-lactic acid (PLLA) and polycaprolactone (PCL)
PLLA (for example, Sculptra) and PCL (for example, Ellansé) are collagen stimulators. PLLA gives gradual volume over weeks to months and usually needs a series of sessions. Some Korean products combine collagen stimulators with HA. These products are not easily reversible.
Permanent fillers
Permanent or semi-permanent synthetic fillers are rarely recommended for facial aesthetics today because complications can appear years later and are difficult to remove.
Common Areas and Typical Longevity
- Lips:
often around six to twelve months, as movement breaks down product faster.
- Nasolabial folds:
often nine to twelve months or more.
- Cheeks and midface:
firmer HA products may last twelve to eighteen months or longer.
- Chin and jawline:
often twelve months or more with firmer products.
- Nose (non-surgical rhinoplasty):
variable; this is a higher-risk area for vascular events.
- Under-eye hollows:
HA can persist for a long time in this area, sometimes beyond a year.
These ranges are general. Longevity depends on the product, the amount used, metabolism, movement in the area and the injection technique. Imaging studies show that some HA can remain in tissue longer than visible results suggest, which is one reason to avoid frequent top-ups without assessment.
Safety Checklist Before Filler
- Confirm the product.
Ask for the brand name, see the sealed box or syringe, and check that it is approved by Korea's Ministry of Food and Drug Safety (MFDS). Ask for the product sticker or lot number for your records.
- Ask who injects.
The physician should perform the injection personally and explain their experience with your chosen area.
- Discuss technique.
Ask whether a needle, cannula or both will be used and why.
- Ask about complications.
A responsible clinic keeps hyaluronidase on hand and has a protocol for vascular occlusion.
- Share your history.
Tell the doctor about previous fillers, threads, permanent implants, allergies, autoimmune disease, cold sores and blood-thinning medication.
- Plan follow-up.
Know how to contact the clinic after hours and after you leave Korea.
Side Effects and Complications
Common and usually temporary
- Swelling, redness and tenderness for a few days
- Bruising, especially in lips and under-eyes
- Small lumps that may settle or need massage as directed
Less common but important
- Vascular occlusion:
filler blocking a blood vessel. Warning signs include severe pain, blanching (white skin), mottled or dusky color, or visual changes. This is an emergency that needs immediate treatment. Blindness is a rare but serious risk, especially in the nose, glabella and forehead.
- Infection or delayed inflammatory nodules,
which can appear weeks or months later.
- Tyndall effect:
a bluish tint when HA is placed too superficially.
- Migration or overfilled appearance
over time.
Who Should Not Have Fillers
- People who are pregnant or breastfeeding
- Those with active skin infection, cold sores or inflammation at the site
- Anyone with a known allergy to the product or lidocaine
- People with uncontrolled autoimmune disease, unless cleared by their doctor
Cost Drivers
Filler is usually priced per syringe, often 1 ml, and varies by brand, product line and the number of syringes needed. Ask the doctor to estimate syringes per area, whether a touch-up is included, and whether dissolving is charged separately. Get a written quote that names the exact product, not just "premium filler."
Travel Timing in Busan
Bruising and swelling usually settle within one to two weeks. Ideally, have filler early enough in your trip to allow a review visit. Pressure changes during flights are not known to move filler, but you should avoid pressing on treated areas. If you notice signs of vascular compromise after leaving the clinic, contact them immediately or seek emergency care.
Frequently Asked Questions
Can filler be removed if I don't like it?
HA fillers can usually be dissolved with hyaluronidase. Collagen stimulators and CaHA cannot be easily removed.
Are Korean filler brands safe?
Many Korean HA fillers are MFDS-approved and widely used. Safety depends heavily on the injector, the area and correct technique.
Is a cannula safer than a needle?
Cannulas may reduce some risks in certain areas, but no technique removes the risk of vascular events entirely.
Key Takeaways
- HA fillers are the most common type and can usually be dissolved.
- Longevity ranges from about six to eighteen months by product and area.
- Confirm the MFDS-approved product, injector experience and complication protocol.
- Severe pain, skin color change or visual symptoms need urgent attention.
