Many people assume a wide face is caused solely by large masseter muscles, and focus only on jaw Botox — yet still do not achieve the V-line they want. The truth is, a blurred jawline is often caused by an overactive platysma muscle pulling the lower face downward, making the entire face look wider and less defined. Seoul Rappoel Clinic uses Korea’s third-generation Coretox botulinum toxin for jawline contouring, precisely relaxing the platysma’s downward pull and allowing the jawline to naturally lift — creating that coveted sculpted Korean V-line profile.
Why is Your Jawline Not Defined?
- Overactive platysma muscle: The platysma connects the jawbone to the collarbone; when overly active, it pulls the jawline downward
- Skin laxity from aging: Collagen loss reduces skin elasticity and support along the jawline
- Submental fat (double chin): Fat accumulation beneath the chin blurs the jawline contour
- Combined masseter hypertrophy: Both wide masseters and a blurred jawline coexist, amplifying a square face appearance
How Coretox Jawline Lifting Works
The treatment involves micro-injections of Coretox into the platysma muscle to selectively weaken its downward pull:
- Neuromuscular blockade: Coretox inhibits acetylcholine release at the platysma neuromuscular junction, reducing muscle contraction
- Release of upward lifting forces: With the platysma’s downward force reduced, the face’s natural upward lifting muscles (including the SMAS layer) can act unopposed
- Gradual jawline elevation: Over 2–4 weeks, the jawline becomes progressively sharper and more defined
- Neck band improvement: Relaxation of the platysma also visibly softens vertical platysmal neck bands
Rappoel’s Coretox Jawline Protocol
- Precision injection points: Multiple micro-injections distributed along the inferior mandibular border and platysmal bands
- Controlled dosing: Total dose of 30–50 units, precisely distributed across injection sites
- Combination with masseter Botox: Can be performed together for a complete V-line transformation
- No downtime: Micro-needle injections are nearly invisible and painless; normal activities resume the same day
Expected Timeline
- 1–2 weeks: Initial feeling of tightness and lift along the jawline
- 2–4 weeks: Jawline contour becomes progressively sharper; V-line effect visible
- 1–2 months: Peak results achieved
- Duration: Approximately 4–6 months; regular maintenance prolongs effect duration
Ideal Candidates
- Individuals with poorly defined jawline contour at rest
- Those whose jawline disappears or drops noticeably when smiling
- Patients with both masseter hypertrophy and jawline blurring seeking full V-line correction
- Those with prominent vertical platysmal neck bands
- Men and women aged 20–50 seeking jawline definition
