Masseter muscle injections help slim the jawline by relaxing enlarged jaw muscles, often caused by clenching or grinding. This treatment can soften a square jaw, create a more contoured lower face, and relieve tension-related symptoms like jaw pain or headaches. Results develop gradually and last several months.

The masseter muscles are one of the strongest muscles in the human body, located on either side of the jaw and responsible for chewing and clenching. Some individuals naturally have strong, enlarged masseter muscles, leading to a square or widened lower face. Others may experience chronic teeth grinding (bruxism) or jaw tension, which can contribute to jaw pain, headaches, and dental complications.

At Haus of Ästhetik, we offer botulinum toxin injections into the masseter muscles to relax the jaw, resulting in a slimmer, more contoured lower face while also alleviating the symptoms of bruxism, jaw pain, and tension headaches.

How Does the Treatment Work?

Botulinum toxin works by temporarily blocking the nerve signals that cause excessive muscle contraction. When injected into the masseter muscles, this results in:

• Relaxation of the jaw muscles, reducing involuntary clenching and grinding.

• Gradual slimming of the lower face, giving a softer, more contoured jawline.

• Alleviation of tension headaches, jaw pain, and temporomandibular joint (TMJ) discomfort.

• Reduced pressure on teeth, which helps prevent excessive wear and damage.


How Can It Affect the Bite and Dental Health?

Masseter muscle relaxation can lead to subtle changes in the bite, particularly in individuals with severe bruxism or a naturally strong bite force. While most people experience no functional issues, it is important to consider:

• Reduction in bite strength – The masseter muscles play a key role in chewing; while botulinum toxin reduces excessive force, it does not completely eliminate function.

• Adjustment period – Some individuals may experience a slight change in how their teeth meet as the masseters relax, but this typically resolves as the muscles adapt.

• Improved TMJ health – By reducing clenching and grinding, botulinum toxin can help alleviate jaw joint pain and tension.

During the consultation, we will assess your bite, facial structure, and symptoms to ensure that this treatment is appropriate for you.

What Does the Procedure Involve?

• Precise botulinum toxin injections are placed into each masseter muscle at key points along the jawline.

• The procedure takes approximately 10–15 minutes to complete.

• Most clients describe the sensation as a small pinprick with minimal discomfort.

• No anaesthesia is required, and normal activities can be resumed immediately.

What to expect from your procedure:

  • Treatment Duration:

    10–15 minutes.

  • Pain Level:

    Minimal discomfort.

  • Downtime:

    There is no downtime, though mild redness or swelling at the injection sites may occur for a few hours.

  • Results Seen:

    Initial effects appear within 5–7 days, with full results visible at 4–6 weeks.

  • Longevity:

    The effects last between 4–6 months, with maintenance treatments required to sustain results.

Long-Term Benefits of Regular Botulinum Toxin Treatments

• Muscle Fatigue & Reduction in Bulk – With repeated treatments, the targeted muscle becomes weaker over time due to reduced activity, leading to a gradual slimming effect in areas such as the jawline, trapezius, and masseter muscles.

• Prevention of Deep Static Lines – Regular use of botulinum toxin reduces repetitive muscle contractions, preventing wrinkles from becoming permanently etched into the skin and resulting in a smoother, more youthful appearance.

• Increased Longevity of Results – As the underlying muscles adapt to reduced movement, many clients find that they require fewer units over time or that results last longer between treatments.

• Gradual Muscle Wastage (Atrophy) – Over time, the muscle experiences atrophy (a decrease in size and strength), leading to longer-lasting results and a reduced need for frequent treatments in some cases.

• Enhanced Facial and Body Contouring – In areas like the jawline, trapezius, or masseter muscles, consistent treatments reduce bulk and refine the contour, creating a naturally sculpted and balanced aesthetic.
