The V-line botox HIFU protocol pairs masseter botox from ₩39,000 (≈ $28) — slimming jaw muscle over 8-12 weeks — with Shurink Universe HIFU from ₩149,000 (≈ $106) tightening jawline skin, sequenced as one written plan by co-directors at Kind Global Clinic Myeongdong.
A wide or heavy lower face is rarely one problem. Masseter hypertrophy — jaw muscle enlarged by clenching, grinding, or genetics — squares the jaw angle from the side of the face; soft-tissue laxity blurs the jawline border and lets early jowls form under it. Botox treats the first mechanism: 50U per protocol dose shrinks the overworked masseter by measurable volume over 8-12 weeks, and Korean split-face studies document comparable masseter reduction at week 8 across major toxin brands. HIFU treats the second: 300-600 focused ultrasound shots along the jawline and submental zone contract collagen at the SMAS and deep dermis, with the lift building over months 2-3. Neither tool does the other's job — botox does not tighten skin, and no energy device shrinks a hypertrophic muscle.
At Kind Global Clinic Myeongdong the protocol starts with the clench test: Dr. Lee Wonjin (KR Medical License 143124) or Dr. Lee Kangin (KR Medical License 141247) has you bite down while palpating the jaw angle — a muscle that bulges hard under the fingers books the botox half, a soft jaw angle with a blurred border books the HIFU half, and the common mixed case books both, HIFU delivered first and toxin injected after the energy pass, routinely in the same visit. Each half keeps its published price, from ₩39,000 (≈ $28) for the Korean-tier toxin to ₩279,000 (≈ $199) for a 600-shot HIFU session, so a muscle-dominant jaw and a laxity-dominant jaw pay for different plans by design. The V-line lifting overview covers the full modality menu, and masseter botox details the muscle half on its own.
