Rappoel uses Coretox to simultaneously relax the masseter and jawline depressor muscles for a V-shape contour<\/div>\n<\/p><\/div>\n<p>Facial contouring is one of the core demands in Korean micro-aesthetics. Many people face both masseter hypertrophy (square jaw) and jawline sagging simultaneously, and single-treatment approaches often yield limited results. Seoul’s Rappoel Dermatology offers a Coretox combination protocol — in the same session, masseter relaxation reduces facial width while jawline lifting improves contour sagging, solving both “wide” and “sagging” contour issues at once.<\/p>\n<h2>Why a Combination Approach Is Needed<\/h2>\n<ul>\n<li><strong>Masseter Hypertrophy:<\/strong> Long-term chewing of hard foods and nighttime bruxism cause masseter enlargement, widening the lower third of the face into a square shape<\/li>\n<li><strong>Jawline Sagging:<\/strong> With age, the platysma and depressor labii inferioris pull the jawline downward, blurring the contour<\/li>\n<li><strong>Dual Concern:<\/strong> Width plus sagging makes the face look both wide and aged, and single treatments only address half the problem<\/li>\n<li><strong>Synergistic Effect:<\/strong> Masseter reduction highlights the jawline, while jawline lifting enhances the slimming effect<\/li>\n<\/ul>\n<h2>Rappoel Combination Protocol<\/h2>\n<ol>\n<li><strong>Pre-Treatment Assessment:<\/strong> The physician evaluates masseter thickness (palpation during clenching), jawline sagging degree, and facial proportions<\/li>\n<li><strong>Masseter Injection:<\/strong> 25-35 units of Coretox per side, injected at 3-4 points into the deep masseter muscle belly<\/li>\n<li><strong>Jawline Injection:<\/strong> 15-20 units of Coretox along the mandibular border to relax the platysma and depressor labii inferioris downward pull<\/li>\n<li><strong>Dose Allocation:<\/strong> Total 50-70 units, individually adjusted based on muscle mass and sagging degree<\/li>\n<li><strong>Total Time:<\/strong> Approximately 15 minutes<\/li>\n<li><strong>Onset:<\/strong> Results visible in 3-7 days, peak effect at 2-4 weeks<\/li>\n<li><strong>Duration:<\/strong> 4-6 months, regular maintenance recommended<\/li>\n<\/ol>\n<h2>Combined Effects<\/h2>\n<ul>\n<li><strong>Reduced Facial Width:<\/strong> Masseter relaxation causes atrophy, reducing lower face width by 5-10mm<\/li>\n<li><strong>Clear Jawline:<\/strong> Jawline lifting creates a smooth contour line from chin to earlobe<\/li>\n<li><strong>V-Shape Contour:<\/strong> Width reduction plus line lifting creates an overall V-shape<\/li>\n<li><strong>Rejuvenation:<\/strong> Jawline lifting improves marionette lines and jowl appearance<\/li>\n<li><strong>No Downtime:<\/strong> Normal activities can resume immediately after injection<\/li>\n<\/ul>\n<p>The key to the Coretox combination protocol lies in precise dose allocation and injection depth control. Superficial masseter injection may affect the smile muscles, while overly deep jawline injection may affect oral function. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, where physicians customize injection protocols based on each patient’s muscle structure and facial proportions.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can masseter slimming and jawline lifting be done together?<\/div>\n<div class=\"faq-a\">Yes, and it is recommended. Both use the same Coretox toxin in a single session, no need for separate appointments. Masseter and jawline injection sites are different and non-interfering, and the combined effect is more dramatic than either treatment alone.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will the combination cause facial expression stiffness?<\/div>\n<div class=\"faq-a\">Not with correct dosing. Coretox doses are precisely calculated — 25-35 units\/side for masseter, 15-20 units\/side for jawline, with total amounts within safe limits. The physician avoids the smile muscles and orbicularis oris, ensuring smile and speech function remain unaffected.

Coretox and filler work through different mechanisms — botox relaxes muscles, filler adds volume — and do not interfere. In fact, chin filler combined with jawline lifting works better: filler enhances the V-shape at the chin tip, while botox clarifies the jawline.

Seoul’s Rappoel Dermatology offers a Coretox combination protocol — in the same session, masseter relaxation reduces facial width while jawline lifting improves contour sagging, solving both “wide” and “sagging” contour issues at once.<\/p>\n<h2>Why a Combination Approach Is Needed<\/h2>\n<ul>\n<li><strong>Masseter Hypertrophy:<\/strong> Long-term chewing of hard foods and nighttime bruxism cause masseter enlargement, widening the lower third of the face into a square shape<\/li>\n<li><strong>Jawline Sagging:<\/strong> With age, the platysma and depressor labii inferioris pull the jawline downward, blurring the contour<\/li>\n<li><strong>Dual Concern:<\/strong> Width plus sagging makes the face look both wide and aged, and single treatments only address half the problem<\/li>\n<li><strong>Synergistic Effect:<\/strong> Masseter reduction highlights the jawline, while jawline lifting enhances the slimming effect<\/li>\n<\/ul>\n<h2>Rappoel Combination Protocol<\/h2>\n<ol>\n<li><strong>Pre-Treatment Assessment:<\/strong> The physician evaluates masseter thickness (palpation during clenching), jawline sagging degree, and facial proportions<\/li>\n<li><strong>Masseter Injection:<\/strong> 25-35 units of Coretox per side, injected at 3-4 points into the deep masseter muscle belly<\/li>\n<li><strong>Jawline Injection:<\/strong> 15-20 units of Coretox along the mandibular border to relax the platysma and depressor labii inferioris downward pull<\/li>\n<li><strong>Dose Allocation:<\/strong> Total 50-70 units, individually adjusted based on muscle mass and sagging degree<\/li>\n<li><strong>Total Time:<\/strong> Approximately 15 minutes<\/li>\n<li><strong>Onset:<\/strong> Results visible in 3-7 days, peak effect at 2-4 weeks<\/li>\n<li><strong>Duration:<\/strong> 4-6 months, regular maintenance recommended<\/li>\n<\/ol>\n<h2>Combined Effects<\/h2>\n<ul>\n<li><strong>Reduced Facial Width:<\/strong> Masseter relaxation causes atrophy, reducing lower face width by 5-10mm<\/li>\n<li><strong>Clear Jawline:<\/strong> Jawline lifting creates a smooth contour line from chin to earlobe<\/li>\n<li><strong>V-Shape Contour:<\/strong> Width reduction plus line lifting creates an overall V-shape<\/li>\n<li><strong>Rejuvenation:<\/strong> Jawline lifting improves marionette lines and jowl appearance<\/li>\n<li><strong>No Downtime:<\/strong> Normal activities can resume immediately after injection<\/li>\n<\/ul>\n<p>The key to the Coretox combination protocol lies in precise dose allocation and injection depth control. Superficial masseter injection may affect the smile muscles, while overly deep jawline injection may affect oral function. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, where physicians customize injection protocols based on each patient’s muscle structure and facial proportions.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can masseter slimming and jawline lifting be done together?<\/div>\n<div class=\"faq-a\">Yes, and it is recommended. Both use the same Coretox toxin in a single session, no need for separate appointments. Masseter and jawline injection sites are different and non-interfering, and the combined effect is more dramatic than either treatment alone.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will the combination cause facial expression stiffness?<\/div>\n<div class=\"faq-a\">Not with correct dosing. Coretox doses are precisely calculated — 25-35 units\/side for masseter, 15-20 units\/side for jawline, with total amounts within safe limits. The physician avoids the smile muscles and orbicularis oris, ensuring smile and speech function remain unaffected. There may be a one-week mild adaptation period, after which expressions are completely natural.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How long do results last? How often should I get maintenance?<\/div>\n<div class=\"faq-a\">Typically 4-6 months. For the first treatment, a follow-up at 4 months is recommended, then adjusted to every 5-6 months based on individual metabolism. Regular maintenance can extend each treatment’s duration, as muscles stabilize at reduced volume with chronic relaxation.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can I get this combination if I already had chin filler?<\/div>\n<div class=\"faq-a\">Yes. Coretox and filler work through different mechanisms — botox relaxes muscles, filler adds volume — and do not interfere. In fact, chin filler combined with jawline lifting works better: filler enhances the V-shape at the chin tip, while botox clarifies the jawline. Allow at least 1 week between treatments.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How much does this combination cost in Korea?<\/div>\n<div class=\"faq-a\">The combination is more cost-effective than treating masseter or jawline separately, as it shares one session and material. Rappoel uses Korean-made Coretox for excellent value. Specific costs vary by individual dosage needs. Consult via WeChat (rappoelkr). The clinic is 3 minutes from Gangnam Station Exit 10.<\/div>\n<\/div>\n<div class=\"cta\">\n<h3>Want a V-Shape Facial Contour?
