How Much Is Masseter Botox in Korea and Where It Leaks

Toxin thins muscle and nothing else, so the first real value in the visit comes from the examination. The doctor feels the jaw while you relax and clench, and some clinics measure the muscle with ultrasound. In a 2015 case report in the Indian Journal of Plastic Surgery, Bhattacharjee and colleagues scanned both masseters before injecting and found the left one thicker, at 14.9 mm against 13 mm on the right.

That kind of baseline is worth more than a quick glance. If the width turns out to be mostly jawbone or cheek fat, the sensible spend is nothing at all, or a different treatment.

Many lower faces are a little lopsided, and a split that ignores this can leave the larger side still prominent. In the same case report, the doctors gave 15 units to the smaller muscle and 25 to the larger one. Six months later the muscles were 2.9 mm and 4.4 mm thinner, the visible asymmetry had eased, and the patient still had a satisfactory contour at 24 months without significant complications.

This was a single patient, so it shows a principle rather than a typical outcome. The practical point is to ask whether your quote assumes equal units per side, and whether the doctor would change that after examining you.

The bite softens within days, but the outline of the face changes over weeks. People who judge the mirror on day five sometimes ask for extra units, then find the jaw slimmer than they wanted a month later. A planned review a few weeks after the session is a fairer point to decide whether anything else is needed.

Ask in advance whether that review visit is part of the jaw package, and whether units added at the review are charged separately or at the same per-unit rate.

Technique rarely has its own menu line, yet it affects how much of the result you keep. Qian and colleagues, writing in Aesthetic Plastic Surgery in 2026, reviewed 239 patients treated with a fanning deep injection: one entry point per side, with the toxin spread in a fan toward the deep lower part of the muscle. Facial width narrowed at all three measured levels, discomfort scores were low, and two patients in that study had a temporary bulge that settled by itself.

The study was retrospective, drawing 239 eligible cases from 6,520 treated people, so it supports asking about method rather than insisting on one.

A single round fades as the nerve endings recover, so a lasting change usually means a series spaced months apart. Anyone comparing how much is jaw Botox in Korea against treatment closer to home should count travel for each round, not just the first. A masseter Botox Korea price quoted once is only one part of that total.
