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.
Why a Combination Approach Is Needed
- Masseter Hypertrophy: Long-term chewing of hard foods and nighttime bruxism cause masseter enlargement, widening the lower third of the face into a square shape
- Jawline Sagging: With age, the platysma and depressor labii inferioris pull the jawline downward, blurring the contour
- Dual Concern: Width plus sagging makes the face look both wide and aged, and single treatments only address half the problem
- Synergistic Effect: Masseter reduction highlights the jawline, while jawline lifting enhances the slimming effect
Rappoel Combination Protocol
- Pre-Treatment Assessment: The physician evaluates masseter thickness (palpation during clenching), jawline sagging degree, and facial proportions
- Masseter Injection: 25-35 units of Coretox per side, injected at 3-4 points into the deep masseter muscle belly
- Jawline Injection: 15-20 units of Coretox along the mandibular border to relax the platysma and depressor labii inferioris downward pull
- Dose Allocation: Total 50-70 units, individually adjusted based on muscle mass and sagging degree
- Total Time: Approximately 15 minutes
- Onset: Results visible in 3-7 days, peak effect at 2-4 weeks
- Duration: 4-6 months, regular maintenance recommended
Combined Effects
- Reduced Facial Width: Masseter relaxation causes atrophy, reducing lower face width by 5-10mm
- Clear Jawline: Jawline lifting creates a smooth contour line from chin to earlobe
- V-Shape Contour: Width reduction plus line lifting creates an overall V-shape
- Rejuvenation: Jawline lifting improves marionette lines and jowl appearance
- No Downtime: Normal activities can resume immediately after injection
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.
