HA Filler · Juvéderm · Belotero
HA filler restores volume in cheeks, tear troughs, lips, nasolabial folds, chin, and jawline. Product is matched to the zone — high-lift gels for cheek and chin, soft gels for lips, superficial gels for fine lines. We stock two brands only: Juvéderm and Belotero.

refresh every 9-18 months depending on zone and product
Same-day return to non-strenuous activity
bruising 0-10 days lip / tear trough
2-4 weeks after swelling settles
Immediate (Day 0)
Visible volume on the injection table. Mild swelling and needle marks normal. Lips swell more than midface for 24-48 hours.
Day 1-3
Swelling peaks at 24-48 hours. Possible bruising at lips and tear trough — concealable with mineral makeup after day 2.
Week 1-2
Swelling resolves; 2-week appearance closer to true outcome. Minor asymmetries addressed at 4-week review.
Month 1
Settled. Top-up volume added if under-corrected. Photographic comparison with baseline.
Month 9-18
Gradual loss — longest persistence in cheek, chin, jawline; shortest in lips and perioral. Repeat planned by lifestyle, not fixed clock.

“Injectables and energy devices are performed by physicians — never delegated to non-physician staff. The clinic is led by a board-certified dermatologist.”
Day 0 (first 4h)

Week 2-4
Final result at 4-week visit. Resume retinoids and acid exfoliants. RF / ultrasound / laser on treated zone — wait 2+ weeks.
Long-term
Annual review. Report any new lump, tenderness, color change, or systemic illness (COVID, dental abscess, flu, major surgery) near filler zone — late-onset nodules can trigger months to years later.
Two brands only — Juvéderm (Allergan / AbbVie) and Belotero (Merz). Both MFDS-approved via licensed Korean distribution. Fewer products means deeper familiarity with each gel's rheology and placement plane. Brand and lot number recorded in your written handover.
Yes. Schedule: arrival day 1 → consultation + injection day 2-3 → photo review day 4-5 before flying. Lip / tear-trough bruising 5-10 days, concealable with mineral makeup. Plan social events 2+ weeks post-injection.
Yes. Dr. Yun routinely recommends no treatment, Sculptra (diffuse volume loss), JUVELOOK / Rejuran (skin quality), or surgical referral when filler is not the right tool. First-time patients receive 0.5-1.5 mL with 2-4 week reassessment — we do not 'finish' your face in one session.
Partially. Hyaluronidase dissolves HA gel — Belotero and Juvéderm Ultra dissolve readily; Voluma is the most resistant and may need repeat sessions. Non-HA fillers (Sculptra, Radiesse) cannot be dissolved. If reversibility matters, we steer toward more responsive products.
Body dysmorphic disorder is a recognized condition where a person is preoccupied with a flaw others see as minor. International consensus now recommends BDD screening before injectables — patients with BDD typically do not feel better after the procedure. We screen with a brief conversation and decline filler with a respectful referral when present.
Cheek and chin 12-24 months (Voluma) · NLF 9-15 months (Vollure) · lips 6-12 months (Volbella) · tear trough 9-18 months (Belotero Balance). Mobile zones wear sooner. These are population ranges — heavy zone-use shortens persistence.
Not if product matches zone and volume is conservative. Pillow face comes from cumulative over-treatment with high-G' gels in lips and superficial cheek. Our default is to undertreat in the first session and add at the 4-week review. Prior poorly-placed filler may need partial hyaluronidase before new product.
A firm lump appearing weeks to years after injection — distinct from immediate swelling. Increasingly recognized with VYCROSS products. Triggers include systemic immune events (COVID, severe flu, dental abscess), local trauma, or none. Most resolve with hyaluronidase, intralesional steroid, or antibiotics. Report any new lump promptly.
Both. Fine needle (27-30G) for precise superficial work (perioral lines, lip border). Blunt cannula for larger-volume zones (22G deep cheek, 25G NLF / tear trough / lip). Instrument selected by zone and product.
