The health and aesthetics of our face and jawline often don't receive the attention they deserve. Yet, our jaw plays a critical role in not only basic functions like chewing and speaking but also in how we present ourselves to the world. A well-defined jawline often signals youth, health, and vitality.

But how effective is Jawzrsize in helping us create these desired results?

Today, we're excited to share the findings of a recent clinical study. Conducted by Martin Giniger, MsD, PhD, Director of Clinical Dental and Dermatological Research at PSC Research Institute, Inc., the study evaluated the efficacy of our Jawzrsize facial fitness device in toning and strengthening the jawline while reducing facial wrinkles.

Study Overview


The study aimed to measure the effectiveness of our Jawzrsize facial fitness devices with resistance levels of 20-pound, 25-pound, and 40-pound. Various scientific and clinical methods were employed, including force meter assessments, digital facial skin analysis, and before-and-after photos.


The study enrolled 20 healthy female and male subjects who met specific inclusion/exclusion criteria.

The evaluation metrics included jaw strength analysis using the Tekscan Novus device and facial wrinkle analysis using the VISIA Complexion Analysis System.

Key Findings

Wrinkle Reduction

The study showed a statistically significant reduction in wrinkle depth by approximately 33% across all areas of the face and neck. The average wrinkle reduction for all subjects ranged from 32.0% to 36.0%, demonstrating the device’s effectiveness in achieving a more youthful appearance.

Increased Jaw Strength

Subjects also experienced an incredible 255% increase in jaw strength, as measured using the Tekscan Novus device. This not only contributes to improved aesthetics but also has functional benefits, including better chewing efficiency.

Subjective Improvements

User feedback was overwhelmingly positive, with:

  • 76% of users feeling more attractive
  • 84% noticing fewer facial lines and wrinkles
  • 80% experiencing a boost in confidence
  • 72% feeling healthier overall

Implications for TMJ Pain and Jaw Health

While the study did not focus on TMJ disorders, the benefits of improved jaw strength and muscle tone could potentially extend to individuals suffering from TMJ pain. Building jaw strength and muscle balance may help stabilize the temporomandibular joint, thus reducing discomfort. However, it’s crucial to consult with healthcare professionals for a tailored treatment plan.
