Nuca Masseter Recharge System
How soon will I feel a difference?
Most users feel their jaw begin to loosen during the first 10-minute routine.
But the real change comes with consistent use. Nuca does not stop at temporary release—it supports the overworked masseters after the rolling massage ends.
Your jaw feels looser, lighter and less guarded.
The relief begins lasting longer instead of disappearing again within a few hours.
Relief lasts for over 24 hours—so you wake up, eat and move through your day without constantly thinking about your jaw.
Results and timelines vary depending on how long the tension has been present and how consistently Nuca is used.
What makes Nuca different from ordinary jaw massage?
Ordinary massage loosens a tight masseter. But the support ends when the massage stops.
Nuca combines rolling release, red light therapy, gentle EMS and vibration across both masseters in one routine.
So Nuca does more than temporarily release stiffness. It gives the released, overworked masseters added recovery support after the rollers stop.
Is Nuca safe and comfortable to use?
Yes. Nuca is lightweight, cordless and designed specifically for the sensitive masseter area.
The rounded rollers glide smoothly across your skin, while the adjustable intensity lets you begin gently and increase it until the sensation feels firm but comfortable.
The smooth rolling massage also works across tense areas such as the back of your neck and shoulders. Follow the included instructions when using the red light therapy or EMS settings.
One charge lasts up to two weeks with typical daily use, and a USB-C charging cable is included.
Nuca should never feel sharp or painful. Start at the lowest setting and stop using it if you experience pain or unusual discomfort.
Has red light therapy for jaw tension been studied?
Yes. Red light therapy has been studied specifically for jaw-muscle pain and temporomandibular discomfort.
Research includes a 2021 systematic review by Campos et al. focused on red light therapy for muscular jaw pain, and a 2021 review by Ahmad et al. examining its effects on pain relief and jaw function.
A 2024 review by Buduru et al. evaluated red light therapy wavelengths from 660 to 940 nm.
Nuca uses 660 nm red light and 850 nm near-infrared light, both within that studied wavelength range.
These studies evaluated red light therapy protocols rather than the Nuca device itself. Treatment settings differed between studies.

WHY THE RELIEF KEEPS FADING
Massage Releases The Tension. But The Muscle Still Needs To Recover.
Stress and night clenching keep your masseters braced for hours at a time.
Years of bracing compress the small vessels running through the masseter, so less blood and oxygen reach the overworked muscle.
Massage loosens the stiffness. But when the routine ends there, the muscle gets no added recovery support.
RELEASE + RECOVERY
Release The Tension. Then Recharge The Muscle.
First, Nuca’s rolling massage releases both masseters at once.
Then red light therapy supports circulation through the released muscle, helping more blood and oxygen reach the tissue.

THE DETAILS
Frequently Asked Questions
How soon will I feel a difference?
Most users feel their jaw begin to loosen during the first 10-minute routine. After approximately 4–7 routines, the relief begins lasting longer instead of disappearing again within a few hours. With consistent use, relief lasts for over 24 hours.
Results and timelines vary with the length of the tension and consistency of use.
What makes Nuca different from ordinary jaw massage?
Ordinary massage releases tension only while the massage is happening. Nuca releases both masseters at once, then combines red light therapy, gentle EMS and vibration to support the muscle after the rollers stop.
Is Nuca safe and comfortable to use?
Nuca is built for the small, sensitive masseter area. Its rounded heads roll smoothly across the skin, and nine comfort levels give you full control over the intensity. Start at level 1 and increase until the pressure feels firm and comfortable.
The lightweight, cordless design also rolls across the back and sides of the neck and the shoulders. Keep it away from the front of the throat, eyes, bony points and irritated or injured skin.
One charge lasts up to two weeks with typical daily use. A USB-C charging cable is included.
How often should I use Nuca?
Use Nuca for one 10-minute routine each day. Daily consistency gives the masseters time to release and receive recovery support without turning jaw care into another demanding routine.
What should the gentle EMS feel like?
Gentle EMS feels like a light tingling or controlled pulsing sensation. It should never feel sharp, painful or overwhelming. Start at level 1, then increase only until the sensation feels firm and comfortable.
Which comfort level should I start with?
Start at level 1 for your first routine. Once your jaw is comfortable with the sensation, move up one level at a time. The best setting is the lowest level that feels effective while remaining completely comfortable.
Can I use Nuca on my neck and shoulders?
Yes. The rounded heads also roll across the back and sides of the neck and over the shoulders. Keep Nuca away from the front of the throat, eyes, spine, bony points and irritated or injured skin.
Can I use Nuca with a night guard, crowns or fillings?
Nuca works externally across the masseter muscles and never goes inside your mouth. Stop and ask your dentist before use if you have recent dental surgery, an active dental problem or specific instructions restricting pressure around the jaw.
Who should not use Nuca?
Do not use Nuca over open wounds, irritated skin, the eyes or the front of the throat. Do not use the EMS function with a pacemaker or another implanted electronic device. Stop immediately if the routine causes sharp pain, numbness or unusual discomfort.
How do I clean Nuca?
Turn the device off, then wipe the massage heads with a soft, lightly damp cloth after use. Dry them completely before storing. Do not submerge the device or clean it under running water.
How long does the battery last?
One charge lasts up to two weeks with typical daily use. Nuca is cordless, compact and USB-C rechargeable, and the charging cable is included with your order.
What arrives with my order?
Your order includes the Nuca Masseter Recharge System, USB-C charging cable and usage instructions. You also receive the digital 7-Day Jaw Relief Plan by email after ordering.
Has red light therapy for jaw tension been studied?
Yes. In a randomized, controlled and double-blind clinical trial, de Sousa et al. (2022) applied 660 nm red and 850 nm infrared LEDs to the TMJ, masseter and temporal muscles and reported reduced pain. Nuca uses those same two wavelengths.
Systematic reviews by Ahmad et al. (2021) and Campos et al. (2021) also reported improvements in TMD pain and jaw function across the research they reviewed.
These studies evaluated red light therapy protocols, not the Nuca device itself.
