The Triangle™ Neck-Up Strength Tool
Designed to work together.
Dr. Katie Kennedy, MD, designed the Triangle™ and Butterfly™ as a synergistic pair.
The Triangle tucks easily into the cheeks and engages the floor-of-mouth muscles, while the hinged Butterfly opens and closes for movements the Triangle can’t do. Each does what the other can’t, so together they work the full muscle complex of the face, mouth, lips, cheeks, jaw and neck.
The complete System includes both tools, the custom case and VIP Member access to 40+ expert-guided videos, all for $89.98 instead of $119.96 for both tools separately.

DESCRIPTION
The Triangle is a doctor-designed resistance tool that primarily activates the surface and mid-level muscle groups in the lips, cheeks, and jawline — while also strengthening deeper muscle groups to restore youthful lift and firmness. This focused training helps build strength, tone, and balance that shape facial contours and support facial symmetry.
Regular use promotes a more defined jawline, restored lift and fullness in the cheeks, smoother smile lines, and enhanced lip shape, tone, and strength, while supporting the functions of airway strength, balanced bite alignment, and lasting jaw comfort.
This tool is sold separately for use as an extra or replacement. The Triangle works best as part of the complete Neck-Up Strength™ System, amplifying results when paired with the Butterfly tool for even greater lift and definition.

YOUR TOP QUESTIONS, ANSWERED
Is the system safe to use every day?
Yes. Designed by a physician, the tools are made from medical-grade silicone and are safe for daily resistance training. Think of it like brushing your teeth — a simple, healthy habit with lasting benefits.
Why do I need both tools?
The Triangle primarily targets surface and mid-level muscles in the lips, cheeks, and jawline, while the Butterfly engages deeper muscle groups for lasting strength. Together, they complete the Neck-Up Strength™ System.
Note: The Triangle is sold separately as a handy extra or replacement.
How do I use it, and how often?
Place the Triangle in your mouth and follow the guided exercises in your instruction guide. Just 3–5 minutes a day.
How often should I replace the tools?
With care, they last a long time. Replace if you notice natural wear — a sign you’ve been building strength consistently. Many keep an extra set for strengthening on the go.
How soon will I see results?
Many notice changes in just a few weeks — less tension, a sharper jawline, or better sleep. Results continue to build the longer you stay consistent.
