50 units across both masseters is the published masseter botox plan at Kind Global Clinic Myeongdong — 25 units per side, the dose validated in Korean clinical trials — priced by brand tier from ₩39,000 (≈ $28) (Korean-made) to ₩179,000 (≈ $128) (Allergan).
Masseter botox units and cost are two halves of one decision, and clinics that quote a price without explaining the units are hiding the variable that actually drives your result. The masseter is a chewing muscle, not a wrinkle line: relaxing it takes a muscle-scale dose, which is why the published plan at Kind Global Clinic Myeongdong is 50 units covering both sides — 25 units per masseter. That per-side dose is not arbitrary. A Korean study of 32 subjects (doi:10.1097/PRS.0b013e3181d0ad03) compared 25 and 35 units per masseter and found both effectively reduced masseter hypertrophy, with the larger dose adding no proportional gain — evidence that a correctly placed 25 units per side does the job for most jaws.
Cost then follows a single question: which botulinum toxin brand fills those 50 units. Kind Global Clinic publishes all four tiers — Domestic Plus at ₩39,000 (≈ $28), Domestic Premium at ₩59,000 (≈ $42), Xeomin at ₩149,000 (≈ $106) and Allergan Botox at ₩179,000 (≈ $128) — with the same KRW price for international and Korean patients and no per-unit surcharges added at the desk. Dr. Lee Wonjin (KR Medical License 143124) or Dr. Lee Kangin (KR Medical License 141247) palpates your masseter while you clench, maps its thickness and bulk, then confirms whether the standard 50-unit plan fits or your case needs an adjusted protocol before any vial is opened. The wider context sits on the masseter botox overview, the Botox hub and the jaw botox page — this guide stays focused on units and cost.
