Dermal filler is an injectable hyaluronic acid (HA) gel used to restore volume the face loses with age, soften static folds, and refine contour in areas such as the cheeks, chin, jawline, and lips. HA is a sugar molecule the body already produces, which is why HA fillers are among the most widely used and best-studied aesthetic injectables worldwide. The gel adds structure exactly where it is placed and draws in a small amount of water, giving a soft, natural cushion rather than a stretched look.
Unlike biostimulators that work gradually by prompting your own collagen, HA filler gives an immediate, visible result you can see on the day. It is also reversible: an enzyme called hyaluronidase can dissolve HA if placement needs adjusting, which is a key reason patients and physicians favour it. Different HA products have different thicknesses and lift, so a deep cheek augmentation uses a firmer gel than a delicate lip or tear-trough correction.
At Reberry Clinic, dermal filler is consultation-led. At our Myeongdong (Seoul) location, Dr. Seung Jae Baek, Medical Director, and the clinic’s doctors assess your facial proportions and choose the product, plane, and volume that suit your goals. International patients receive full English support at 5, Myeongdong 10-gil, Jung-gu, Seoul, about 5 minutes from Myeongdong Station.
Hyaluronic acid filler is a cross-linked HA gel: the HA chains are chemically bonded so the gel resists breakdown and holds its shape for months rather than dissolving in days. Manufacturers tune two properties, the degree of cross-linking and the gel’s firmness (G prime), so a single family may offer 3 to 5 products ranging from a soft, spreadable gel for fine lines to a robust, high-lift gel for deep structural volume. The clinic’s doctors match the product to the target: a firmer gel on the deep cheek bone for lift, a softer gel in the superficial lip or tear trough to avoid lumps or a bluish tint.
Placement depth matters as much as the product. Filler is injected with a fine needle or a blunt-tipped cannula into a specific plane, often supraperiosteal (on the bone) for structural volume or more superficial for fine detail. A cannula moves through tissue with less trauma and is often preferred in delicate, vessel-rich zones. Because HA draws water, results settle over roughly 2 weeks as initial swelling resolves.

The clinic’s doctors map where volume has been lost across the 3 zones (upper, mid, lower face) and agree your goals before choosing any product.
A firmer HA gel is chosen for deep structural lift and a softer gel for fine areas, selecting from the 3 to 5 firmness grades in a filler family.
Topical anaesthetic is applied for about 15 to 20 minutes, and most modern fillers also contain lidocaine to improve comfort during injection.
Using a fine needle or blunt cannula, the doctor places small aliquots into 1 or more planes, checking symmetry as they build volume gradually.
The area is gently moulded and reviewed, and each treated area usually takes about 15 to 30 minutes in total.
Initial swelling settles over roughly 2 weeks, and a review can fine-tune the result if a small top-up is needed.

At our Myeongdong (Seoul) location, Dr. Seung Jae Baek and the clinic’s doctors assess your face, agree goals, and select the product in English.
After numbing, each area is treated in about 15 to 30 minutes, and you can usually return to light activities the same day.
A single-area session is short, while a fuller facial plan may combine several areas across one visit.
You see volume immediately, with the final look settling over roughly 2 weeks as swelling resolves.
Results typically last 6 to 18 months; avoid heavy heat and pressure for 24 to 48 hours and return for review if a top-up is wanted.



Dermal filler is an injectable hyaluronic acid gel that restores lost facial volume, softens folds, and refines contour such as cheeks, chin, and lips. Because HA is a sugar the body already makes, it integrates smoothly and gives an immediate, natural-looking result. You can explore the full range on our injectable fillers page.
Dermal filler is treated at our Myeongdong (Seoul) location, at 5, Myeongdong 10-gil, Jung-gu, about 5 minutes from Myeongdong Station. Dr. Seung Jae Baek, Medical Director, and the clinic’s doctors provide consultation-led care with full English support for international patients visiting central Seoul.
Most healthy adults with age-related volume loss, folds, or a wish to refine cheeks, chin, or lips are suitable candidates. A consultation confirms whether HA filler, a biostimulator, or a combination fits your goals. Pregnancy, active infection, or certain allergies are reasons to defer, which your doctor reviews first.
Discomfort is usually mild because topical anaesthetic is applied for about 15 to 20 minutes and most modern HA fillers contain lidocaine. Many patients describe brief pressure or a pinch rather than pain. Sensitive areas like the lips can feel more tender, so numbing is adjusted to keep you comfortable throughout.
Each treated area usually takes about 15 to 30 minutes, so a single-area session is quick. A fuller plan covering several areas can be combined in one visit and takes longer. Because it is a walk-in, walk-out procedure, many international patients fit it around sightseeing in central Seoul.
Results typically last 6 to 18 months, depending on the product, the area, and your metabolism. Firmer gels in structural areas like the cheeks tend to last longer than softer gels in mobile areas like the lips. Your doctor advises on a maintenance schedule so the result stays natural over time.
HA filler is not a permanent implant; it gradually resorbs over months, which many patients see as an advantage. It is also reversible, since an enzyme called hyaluronidase can dissolve HA if placement needs adjusting. This safety margin is a key reason HA is favoured over non-dissolvable fillers.
Downtime is minimal for most facial areas, with many patients returning to normal activities the same day. Mild swelling, redness, or small bruises can appear and usually settle within a few days to about 2 weeks. Lips tend to swell most initially, so plan sensitive treatments a few days before big events.
You see volume immediately, but the final, settled look appears over roughly 2 weeks as initial swelling resolves and the gel integrates. This is why doctors often under-correct slightly and review afterwards. If a small top-up is wanted, it is easy to add once the first result has settled.
HA filler adds immediate, reversible volume, while Juvelook Volume is a PDLLA-based volumiser that builds your own collagen more gradually and lasts longer. Filler suits patients wanting an instant, adjustable change, whereas biostimulators suit those seeking a slower, longer-developing improvement in both volume and skin quality.
Yes, filler is often combined with treatments that address different concerns, such as a thread lift for sagging or skin boosters for texture. Your doctor sequences and doses each so results look balanced and the face is not over-volumised. A tailored plan is agreed at consultation based on your goals.
Common effects are temporary redness, swelling, tenderness, and occasional bruising that settle within days. Rare but serious risks include vascular occlusion, reported in roughly 0.001 to 0.01 percent of treatments, which is why anatomy-guided, physician-led injection matters. Your doctor keeps hyaluronidase on hand and explains warning signs before you begin.
The clinic’s doctors match product firmness to the target area, choosing a robust gel for deep structural lift and a soft gel for delicate lips or tear troughs. A filler family may offer 3 to 5 grades, so the choice reflects your anatomy and goals. See our injectable fillers page for more.
HA filler is widely performed and generally considered safe when a trained doctor uses appropriate products, planes, and technique. A consultation reviews your medical history and reduces avoidable risks. You can read more about how injectables are approached on our injection treatment page before booking.
Avoid heavy exercise, saunas, and significant heat or pressure on the area for about 24 to 48 hours, and skip alcohol on the day to limit bruising. Gentle skincare is fine, and your doctor gives area-specific advice. A supportive skin care routine helps keep skin healthy between visits.
For filler alone, 1 to 2 days in Seoul is usually enough, allowing a consultation, the treatment, and a short review. Many international patients treat it as a walk-in visit near Myeongdong. If you plan multiple areas or want to see swelling settle, adding a couple of days is helpful.
Yes, flying within a day or so is generally fine after HA filler, as it is minimally invasive. Cabin air is drying, so hydrate and avoid pressing on treated areas. If you had extensive work, allow a little time for early swelling before travelling so any review can be done in Seoul.
International patients can complete filler in a single visit, and our English-speaking team offers remote check-ins between trips if you have questions as it settles. Because HA is reversible and adjustable, small refinements can be planned for a future visit. Your treatment notes are kept on file for continuity of care.
| HA Dermal Filler | Juvelook Volume | Thread Lift | |
|---|---|---|---|

| Best for | Immediate volume, folds, lips, and contour refinement | Gradual volume plus collagen quality over time | Sagging and drooping that needs mechanical lift |
| Onset | Immediate, visible on the day | Gradual over weeks as collagen builds | Immediate lift that continues as threads anchor |
| Reversibility | Reversible with hyaluronidase | Not reversible; resorbs slowly on its own | Not reversible; threads dissolve over months |
| Downtime | Little to none for most areas | Minimal, occasional small bumps early on | A few days of swelling and tightness |
| Longevity | Typically 6 to 18 months by product and area | Often longer as it builds collagen | Around 12 to 18 months as threads resorb |
| Cost context | Depends on product and syringes used | Depends on vials and sessions | Depends on thread number and type |
