Face Filler in Seoul | Hyaluronic Acid Dermal Filler

The two are not interchangeable on price alone. Juvéderm (Allergan, US) and Restylane (Galderma, Sweden) are the most widely studied imported HA fillers, with large global safety registries and the easiest continuity of care if you treat in multiple countries. Korean domestic brands Yvoire (LG Chem) and Neuramis (HUONS) are MFDS-approved with published Korean prospective postmarketing safety data. Per-syringe price is typically lower for Korean brands. International patients often prefer imported brands so a dermatologist in their home country can recognize and continue the product. Korean residents and patients prioritizing value often select Korean brands. Dr. Yun walks you through the trade-off without a sales bias toward either; brand and lot are recorded in your written handover regardless.

Yes — face filler is one of the few procedures realistically completed in a single visit. The injection itself takes 30-60 minutes after a thorough consultation. Recommended trip shape: arrival day 1, consultation + injection day 2 or 3, photo review day 4-5 before flying. Avoid same-day injection on arrival because jet lag and dehydration worsen swelling. Lip and tear-trough work may bruise for 5-10 days — concealable with mineral makeup. Plan important social events for at least 2 weeks after injection. If you need 2+ zones treated, we can sometimes split into two sessions 5-7 days apart within the same trip; otherwise the second zone is best scheduled for a return visit.

Yes. Dr. Yun routinely recommends no treatment, Sculptra (for diffuse tissue volume loss), JUVELOOK / Rejuran (for skin quality), or surgical referral when filler is not the right tool. For first-time patients we typically place 0.5-1.5 mL across one or two zones and ask you to return in 2-4 weeks to assess — we do not 'finish' your face in one session. A patient leaving consultation with a no-treatment recommendation is part of how we work, not an exception.

Hyaluronic acid filler is partially reversible — but 'fully reversible' phrasing is misleading. Hyaluronidase (an enzyme) dissolves HA gel, and we stock it on-site for emergencies. Reversibility varies by product: Restylane-L responds to very small doses, Juvéderm Ultra Plus and Volbella require moderate doses, and Voluma is the most resistant — full dissolution often needs repeat sessions because of its VYCROSS crosslinking. Hyaluronidase does not reverse a fibrotic capsule, a granuloma, vascular tissue damage, or anatomic stretch from years of repeat injection. Non-HA fillers (Sculptra PLLA, Radiesse CaHA) cannot be dissolved at all. We discuss this honestly at consultation; if reversibility is essential to your comfort, we steer toward the more hyaluronidase-responsive products.

Body dysmorphic disorder is a recognized psychiatric condition in which a person is preoccupied with a perceived flaw that others see as minor or invisible. International dermatology consensus now recommends BDD screening as standard of care before cosmetic injectables, because patients with BDD typically do not feel better after the procedure — they often request more product, develop pillow face from over-treatment, and report worse psychological outcomes. We use a brief validated screening conversation at consultation; if BDD features are present we decline filler and offer a respectful referral. This is not a judgment of the patient — it is honest care that prevents harm. The same logic applies when a patient's stated goal will not be solved by filler; we will say so and discuss alternatives including no treatment.

Vascular occlusion — the injection of filler into or against a facial artery, blocking blood flow. In the worst case it causes skin necrosis, stroke-like neurologic events, or permanent blindness. The highest-risk zones are glabella (between the eyebrows), nose, nasolabial fold, and forehead. The vision-loss window is minutes, not hours, and rescue with hyaluronidase often fails because the enzyme cannot reach inside an arterial lumen in time. We minimize risk by knowing the anatomy in detail, using a blunt cannula in higher-risk zones, injecting small low-pressure aliquots, watching for skin-perfusion changes immediately after each deposit, and keeping flooding-dose hyaluronidase stocked on-site with a published-protocol emergency plan. The risk is small but real, and we discuss it before — not after — your injection. We do not claim to have never had a complication; any clinic that does is not being honest.

Persistence depends on the product, the zone, and your tissue mobility. Immobile zones (cheek, chin, jawline) hold longer because the gel is not constantly compressed and stretched. Mobile zones (lips, NLF, perioral) wear sooner. Typical ranges: cheek and chin 12-24 months with Voluma or Lyft · nasolabial fold 9-15 months with Vollure or Defyne · lips 6-12 months with Volbella, Kysse, or Refyne · tear trough 9-18 months with Restylane-L, Eyelight, or Belotero Balance. These are population ranges — heavy exercise, high metabolic rate, and high zone-use (heavy speaking, kissing, eating) shorten persistence.

Not if the product is matched to the zone and the volume is conservative. Pillow face — the over-projected, doll-like look — comes from cumulative over-treatment, typically with high-G' lifting gels placed in lips and superficial cheek across many sessions. Our default is to undertreat in the first session and add at the 4-week review if needed. We photograph baseline and at 4 weeks so we make additive decisions on evidence, not memory. If you already have prior filler from another clinic, Dr. Yun may recommend partial hyaluronidase before placing new product — stacking on top of poorly-placed filler is how pillow face accumulates.

Because per-syringe pricing is misleading. A single syringe sounds modest, but a typical maintenance cadence of 1-2 syringes every 12-18 months across a decade adds up to a meaningful cumulative figure. Many patients begin filler in their late 20s or early 30s and continue for 30 years. Sculptra (collagen biostimulator) may give 2-3 years of volume per series, and at a higher cost per treatment but lower cost per year of effect for some zones. Surgical options (midface lift, fat grafting) carry higher upfront cost but can be one-and-done for some anatomies. We surface these numbers at consultation so you choose a strategy, not a syringe.

A late-onset nodule is a firm lump that appears weeks to years after filler injection — distinct from immediate swelling. It is increasingly recognized in the literature, especially with VYCROSS-platform products (Voluma, Vollure, Volbella). Triggers include systemic immune events (COVID infection, COVID vaccine, severe flu, dental abscess), local trauma, or no identifiable cause. Most resolve with hyaluronidase, intralesional steroid, oral antibiotics, or a combination — but the workup needs a dermatologist who recognizes the pattern. Pivotal trial follow-up for filler was only 6-12 months, so product labels under-describe long-term events. If you develop a new lump months or years after injection — anywhere on the face — return to us or to a dermatologist familiar with filler complications.

Both have a place. A needle (27-30G) is precise for small-volume superficial work — perioral lines, lip border definition, philtral column. A blunt cannula (22G for deep cheek and jawline; 25G for NLF, tear trough, and lip; 27G for fine perioral) pushes through tissue planes rather than piercing vessels, and is preferred for larger-volume zones because it reduces — though does not eliminate — vascular occlusion risk. Dr. Yun selects the instrument by zone and product. In high-risk zones (glabella, nose, NLF), cannula is the default. Aspiration is performed as an adjunct safety step, not the primary safety reliance — the literature shows aspiration sensitivity is approximately one-third, so we layer multiple safety steps.

Yes — 1-week and 4-week video check-ins are available in your language via messenger (KakaoTalk / LINE / Zalo / WhatsApp / WeChat). This is critical for international patients because the late-onset complication risk window extends weeks to months after you fly home. We review the zone visually, ask about new lumps or color changes, and coordinate with your home dermatologist if escalation is needed. Your written record (brand, lot, volume, zone, instrument) is also sent in advance so a home dermatologist can act quickly if needed.

Aggressively packaged pricing usually reflects one or more of: domestic-only generic product (not always disclosed), high-volume non-dermatologist injectors, or parallel-imported product without verified cold-chain. Counterfeit and parallel-imported filler has been documented in the Korean dermatology literature. Our pricing is itemized — brand, lot number, zone, volume — and shared in writing. You are welcome to compare. If you go elsewhere, we recommend confirming: (1) injector is a Board-Certified dermatologist or plastic surgeon, (2) product is supplied through the licensed Korean distributor, (3) hyaluronidase is stocked on-site, (4) you receive a written record of brand and lot, (5) a video follow-up is offered.

HA filler is best for localized volume in a discrete zone. Consider Sculptra (PLLA collagen biostimulator) when the volume loss is diffuse across the midface and you prefer 2-3 years per series rather than annual top-ups; Sculptra works on a different mechanism — your own collagen — and is not a substitute when you need immediate same-day volume. Consider surgical referral (midface lift, fat grafting, or eyelid surgery) when you have advanced soft-tissue descent, severe tear-trough deformity, or when you have been on filler for 10+ years and stretch is now contributing to the appearance you are trying to fix. Consider JUVELOOK or Rejuran when your concern is skin quality (texture, fine lines, crepiness) — not volume. Dr. Yun will tell you when filler is not the right tool, even though we offer it.
