Rappoel Dermatology Clinic in Gangnam, Seoul offers precise masseter botulinum toxin injections to slim the jawline and create a natural V-shaped face \u2014 no surgery needed. 3-min walk from Gangnam Station Exit 10.<\/div>\n<\/p><\/div>\n<h2>What Causes a Square Jaw?<\/h2>\n<p>A square or wide jawline is most commonly caused by masseter muscle hypertrophy. The masseters are located at the lower jaw angles \u2014 excessive chewing of hard foods, teeth grinding (bruxism), or genetic predisposition can cause them to enlarge, making the jaw appear wide and angular. Botulinum toxin injection is currently the most effective non-surgical solution for masseter reduction.<\/p>\n<div class=\"highlight\">\n<p>\ud83d\udccd Rappoel Dermatology Clinic \u00b7 5F, 77 Seocho-daero, Seocho-gu, Seoul \u00b7 3-min walk from Gangnam Station Exit 10<\/p>\n<\/div>\n<h2>Masseter Botox at Rappoel Clinic<\/h2>\n<h3>Precision Masseter Targeting<\/h3>\n<p>Rappoel doctors first assess both masseter sizes and symmetry, then design a personalized injection plan. Botulinum toxin is injected into the masseter at the jaw angle, blocking neuromuscular signals to gradually reduce muscle volume. Changes begin 2\u20134 weeks post-injection, with the face noticeably slimmer by weeks 6\u20138.<\/p>\n<h3>Benefits Beyond Face Slimming<\/h3>\n<p>Masseter reduction not only creates a V-shaped face \u2014 it also improves teeth grinding, reduces temporomandibular joint pressure, and relieves jaw tension. For patients with bruxism, masseter botox is a highly beneficial multi-effect treatment.<\/p>\n<h2>Procedure Details<\/h2>\n<div class=\"card\">\n<div class=\"card-title\">Procedure Time<\/div>\n<p>Consultation + injection: approximately 20\u201330 minutes total. No anesthesia required \u2014 normal daily activities can resume immediately.<\/p>\n<\/div>\n<div class=\"card\">\n<div class=\"card-title\">Post-Treatment Notes<\/div>\n<p>Avoid excessive chewing or pressing the injection site for 4 hours post-treatment. Avoid intense exercise and alcohol on the same day. Mild tenderness at the injection site is normal and temporary.<\/p>\n<\/div>\n<h2>Results Timeline and Long-Term Plan<\/h2>\n<p>First-time results last 4\u20136 months. With regular maintenance, the masseter gradually atrophies and duration extends to 6\u20139 months \u2014 some patients who maintain treatment for 2 years achieve even longer-lasting improvement. Maintenance injections every 4\u20136 months are recommended.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Is masseter botox really effective for slimming the face?<\/div>\n<div class=\"faq-a\">Yes \u2014 masseter botox is one of the most effective non-surgical approaches for square jaw reduction.

Rappoel Dermatology Clinic in Gangnam, Seoul offers precise masseter botulinum toxin injections to slim the jawline and create a natural V-shaped face \u2014 no surgery needed. 3-min walk from Gangnam Station Exit 10.<\/div>\n<\/p><\/div>\n<h2>What Causes a Square Jaw?<\/h2>\n<p>A square or wide jawline is most commonly caused by masseter muscle hypertrophy. The masseters are located at the lower jaw angles \u2014 excessive chewing of hard foods, teeth grinding (bruxism), or genetic predisposition can cause them to enlarge, making the jaw appear wide and angular. Botulinum toxin injection is currently the most effective non-surgical solution for masseter reduction.<\/p>\n<div class=\"highlight\">\n<p>\ud83d\udccd Rappoel Dermatology Clinic \u00b7 5F, 77 Seocho-daero, Seocho-gu, Seoul \u00b7 3-min walk from Gangnam Station Exit 10<\/p>\n<\/div>\n<h2>Masseter Botox at Rappoel Clinic<\/h2>\n<h3>Precision Masseter Targeting<\/h3>\n<p>Rappoel doctors first assess both masseter sizes and symmetry, then design a personalized injection plan. Botulinum toxin is injected into the masseter at the jaw angle, blocking neuromuscular signals to gradually reduce muscle volume. Changes begin 2\u20134 weeks post-injection, with the face noticeably slimmer by weeks 6\u20138.<\/p>\n<h3>Benefits Beyond Face Slimming<\/h3>\n<p>Masseter reduction not only creates a V-shaped face \u2014 it also improves teeth grinding, reduces temporomandibular joint pressure, and relieves jaw tension. For patients with bruxism, masseter botox is a highly beneficial multi-effect treatment.<\/p>\n<h2>Procedure Details<\/h2>\n<div class=\"card\">\n<div class=\"card-title\">Procedure Time<\/div>\n<p>Consultation + injection: approximately 20\u201330 minutes total. No anesthesia required \u2014 normal daily activities can resume immediately.<\/p>\n<\/div>\n<div class=\"card\">\n<div class=\"card-title\">Post-Treatment Notes<\/div>\n<p>Avoid excessive chewing or pressing the injection site for 4 hours post-treatment. Avoid intense exercise and alcohol on the same day. Mild tenderness at the injection site is normal and temporary.<\/p>\n<\/div>\n<h2>Results Timeline and Long-Term Plan<\/h2>\n<p>First-time results last 4\u20136 months. With regular maintenance, the masseter gradually atrophies and duration extends to 6\u20139 months \u2014 some patients who maintain treatment for 2 years achieve even longer-lasting improvement. Maintenance injections every 4\u20136 months are recommended.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Is masseter botox really effective for slimming the face?<\/div>\n<div class=\"faq-a\">Yes \u2014 masseter botox is one of the most effective non-surgical approaches for square jaw reduction. Changes begin within 2\u20134 weeks, with peak results at 6\u20138 weeks: a noticeably narrower jawline and smoother facial contour.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will masseter botox affect my ability to chew?<\/div>\n<div class=\"faq-a\">No. The masseter retains sufficient chewing function even after reduction. Some patients notice slightly reduced bite force initially, but normal eating is completely unaffected \u2014 full adaptation occurs within 1\u20132 weeks.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How long does masseter botox last? How often do I need touch-ups?<\/div>\n<div class=\"faq-a\">First-time results last 4\u20136 months. With regular maintenance, the muscle gradually atrophies and duration extends to 6\u20139 months. Touch-up every 4\u20136 months is recommended \u2014 long-term maintenance yields increasingly durable results.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can masseter botox cause facial asymmetry?<\/div>\n<div class=\"faq-a\">Rappoel doctors carefully assess both masseter sizes before treatment and adjust dosage for any existing asymmetry \u2014 ensuring balanced improvement on both sides. Minor asymmetry can be fine-tuned with a touch-up injection 4 weeks later if needed.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How do I book masseter botox at Rappoel Clinic?<\/div>\n<div class=\"faq-a\">Book via WeChat (rappoelkr) or Line (rappoelkr).
