No matter how well you care for your face, horizontal neck lines (commonly called “turkey neck” or “necklace lines”) instantly reveal your true age. The neck ages rapidly — its skin is half the thickness of facial skin and loses collagen faster. Coretox botulinum toxin for the platysma muscle is the most effective non-surgical treatment for dynamic neck lines, and Rappoel Dermatology Clinic in Seoul offers precise, natural neck rejuvenation.
Why Neck Lines Form
- Platysma overactivity: This thin sheet muscle running vertically across the front of the neck pulls skin horizontally when contracted
- Thin, fragile skin: Neck skin is half as thick as facial skin, with faster collagen loss
- Tech neck: Prolonged downward phone/screen posture creases the neck skin repeatedly
- Sun damage: The neck is constantly exposed to UV, accelerating photoaging
- Natural aging: Declining collagen and elastin reduce structural support
How Coretox Treats Neck Lines
When injected into the platysma, Coretox partially relaxes this muscle, reducing the downward and outward pull on neck skin. With reduced platysma contraction, horizontal lines visibly smooth out, and the neck surface becomes more even.
Coretox neck treatment also improves:
- Vertical platysmal bands: Relax prominent vertical cords on the neck sides
- Jawline definition: Relaxed platysma tightens the jaw-to-neck transition
- Overall neck youthfulness: Eliminating dynamic neck lines creates a smoother appearance
Rappoel Neck Coretox Technique
Neck botulinum toxin is a highly technique-sensitive procedure — too much can affect swallowing or neck control, too little yields no result. The director customizes each treatment:
- Low-dose, multi-point micro-injection across the platysma
- Superficial placement only — deep swallowing muscles are unaffected
- Zoned approach covering horizontal lines and vertical bands
- Conservative first treatment with gradual dose refinement
Results Timeline
- Visible improvement at 7–14 days post-injection
- Duration: 3–5 months
- Recommended maintenance: every 4–6 months
- Combine with Rejuran neck PDRN for static wrinkle improvement
