In some people it is enlarged, a condition called masseter hypertrophy, which can make the lower face look wider or more angular. Clenching and grinding the teeth can be one contributing factor.<\/p>\n<p>Jawline slimming with botulinum toxin does not remove bone or fat. It targets the muscle only, so it suits a lower face that looks broad because of muscle rather than fat or bone.<\/p>\n<h3>Approval status in Japan<\/h3>\n<p><strong>Botox Vista<\/strong> (Allergan Aesthetics, an AbbVie company) received an additional indication in Japan for the treatment of masseter hypertrophy in adults. A press release published on 27 August 2026 reports that approval was granted on 24 August 2026. Before this change, masseter treatment was outside the product&#8217;s listed indications, so older articles describing it as unapproved may be out of date.<\/p>\n<p>Note that this approval applies to that specific product. Approval status, insurance coverage and self-pay (cosmetic) treatment are separate matters, and cosmetic jawline slimming is generally paid for out of pocket. Please confirm with the clinic which product will be used and how it is regulated.<\/p>\n<h2>How Jawline Botox Works<\/h2>\n<figure style=\"margin: 1.5em 0;\"><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: auto; border-radius: 8px;\" title=\"Jawline slimming Botox Tokyo \u2014 How Jawline Botox Works\" src=\"https:\/\/kojihifu.com\/english\/wp-content\/uploads\/2026\/09\/pexels_4586708_1790315323.webp\" alt=\"Jawline slimming Botox Tokyo \u2014 How Jawline Botox Works\" \/><\/figure>\n<p><strong>Botulinum toxin<\/strong> type A blocks the signal between nerve and muscle, so the injected muscle relaxes. When a muscle is used less, it can gradually become thinner, which may soften the contour of the lower face.<\/p>\n<p>A doctor injects small amounts into the masseter, usually at several points on each side. A published review of the literature (Ferrillo et al., 2025) reports total doses of roughly 24 to 60 units for onabotulinumtoxinA or incobotulinumtoxinA products, and 60 to 300 units for abobotulinumtoxinA, which is measured on a different scale. Units are not interchangeable between brands, so the dose should be decided by your physician.<\/p>\n<h2>Expected Results and Duration<\/h2>\n<figure style=\"margin: 1.5em 0;\"><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: auto; border-radius: 8px;\" title=\"Jawline slimming Botox Tokyo \u2014 Expected Results and Duration\" src=\"https:\/\/kojihifu.com\/english\/wp-content\/uploads\/2026\/09\/pexels_7581583_1790315324.webp\" alt=\"Jawline slimming Botox Tokyo \u2014 Expected Results and Duration\" \/><\/figure>\n<p>Results appear gradually rather than immediately, because the muscle needs time to weaken and slim. The same 2025 review describes effects lasting about 3 to 4 months, which is why the treatment is considered temporary.<\/p>\n<p>In a randomized, triple-blind trial in 26 women (Nobre et al., Scientific Reports, 2024), 75 units of abobotulinumtoxinA were injected into each masseter. Muscle thickness decreased at 1 month after a single injection but had recovered by 3 months. Individual results vary, and no outcome can be guaranteed.<\/p>\n<h3>What People Often Get Wrong<\/h3>\n<p><strong>Misconception 1: &#8220;Jaw Botox is off-label in Japan.&#8221;<\/strong><\/p>\n<p>This was true of earlier product labelling, but a masseter hypertrophy indication for Botox Vista was reported approved in August 2026. It is still worth asking which product your clinic uses.<\/p>\n<p><strong>Misconception 2: &#8220;More frequent injections simply keep shrinking the muscle, with no downside.&#8221;<\/strong><\/p>\n<p>In the trial above, the group given a repeat injection at 3 months still had reduced left masseter thickness at 6 months, and the authors reported sustained reductions in muscle electrical activity and impaired chewing performance. The study was small, but it suggests that repeated dosing deserves caution and that the schedule should be set with a physician.<\/p>\n<h2>Cost in Tokyo<\/h2>\n<figure style=\"margin: 1.5em 0;\"><img decoding=\"async\" style=\"width: 100%; max-width: 100%; height: auto; border-radius: 8px;\" title=\"Jawline slimming Botox Tokyo \u2014 Cost in Tokyo\" src=\"https:\/\/kojihifu.com\/english\/wp-content\/uploads\/2026\/09\/pexels_7446681_1790315325.webp\" alt=\"Jawline slimming Botox Tokyo \u2014 Cost in Tokyo\" \/><\/figure>\n<p>Pricing depends on the product used and the number of units.
