Jaw Slimming & Masseter Relaxation: Everything You Need to Know

A well-defined, balanced jawline is often associated with a youthful and attractive appearance. However, for some individuals, an overactive masseter muscle (the large muscle at the back of the jaw) can create a square, bulky jawline, leading to facial asymmetry, jaw tension, or even discomfort from teeth grinding (bruxism). 

If you’re looking for a non-surgical way to achieve a slimmer, more contoured jawline, jaw slimming and masseter relaxation treatments at Laserase Medical offer an effective solution. Using targeted muscle-relaxing injections, this treatment softens the jawline, relieves tension, and creates a more V-shaped facial profile. 

In this guide, we’ll explore how jaw slimming works, who it’s suitable for, what to expect from the procedure, and why Laserase Medical is the ideal clinic for this treatment. 

What is Jaw Slimming & Masseter Relaxation? 

Jaw slimming with muscle-relaxing injections is a non-invasive treatment that reduces the size of the masseter muscle, leading to a softer, more contoured jawline. 

The masseter muscle plays a key role in chewing and clenching, but when overactive or enlarged, it can lead to: 

✔ A square, wide jawline that may appear disproportionate. 

✔ Facial tension or discomfort from jaw clenching and teeth grinding. 

✔ Headaches and jaw pain due to excessive muscle activity. 

✔ Asymmetry in the lower face, making one side appear more prominent than the other. 

By injecting a small amount of botulinum toxin into the masseter muscle, the treatment gradually reduces muscle size, resulting in: 

✔ A more sculpted and contoured lower face. 

✔ Reduced tension, pain, and discomfort from teeth grinding or clenching. 

✔ A natural, balanced look without invasive surgery. 

The treatment is safe, effective, and requires minimal downtime, making it a popular choice for those seeking facial contouring without surgery. 

Who is Jaw Slimming Suitable For? 

This treatment is ideal for individuals who: 

✔ Have a square, wide, or bulky jawline and want a softer, more tapered look. 

✔ Experience jaw pain, tension headaches, or teeth grinding due to an overactive masseter muscle. 

✔ Want a non-surgical alternative to jawline contouring procedures. 

✔ Prefer a natural-looking facial slimming treatment with minimal downtime. 

Who Should Avoid This Treatment? 

While masseter relaxation is safe for most individuals, it may not be suitable for: 

✖ Those who have a naturally narrow or small jawline. 

✖ People with certain neuromuscular disorders. 

✖ Pregnant or breastfeeding women. 

✖ Anyone with a known allergy to botulinum toxin. 

If you’re unsure whether you’re a suitable candidate, a consultation at Laserase Medical will help determine the best treatment for your needs. 

How Does Jaw Slimming Treatment Work? 

The procedure involves a series of small injections of a muscle-relaxing agent (such as botulinum toxin) directly into the masseter muscle. This temporarily weakens the muscle, reducing its size over time and slimming the lower face. 

Step-by-Step Process: 

1. Consultation & Assessment 

Your journey begins with a consultation at Laserase Medical, where an experienced practitioner will: 

✔ Assess your jaw structure and masseter muscle size. 

✔ Discuss your goals and expectations. 

✔ Explain how the treatment works and what results to expect. 

2. The Treatment Session 

✔ The treatment area will be cleansed and prepped. 

✔ A series of small, precise injections will be administered into the masseter muscle. 

✔ The process takes around 10–15 minutes and involves minimal discomfort. 

Most patients describe the sensation as a quick pinprick, and no anaesthetic is usually required. 

3. Recovery & Aftercare 

One of the benefits of masseter relaxation treatment is that there is no downtime. You can return to work and normal activities immediately. 

Aftercare Tips: 

✔ Avoid massaging or pressing the treated area for 24 hours. 

✔ Refrain from strenuous exercise on the day of treatment. 

✔ Do not consume alcohol or caffeine immediately after the session. 

✔ Stay upright for at least 4 hours post-treatment. 

How Long Does It Take to See Results? 

Unlike dermal fillers, which provide instant volume, muscle-relaxing injections work gradually. 

✔ 1–2 weeks – Initial softening of the masseter muscle. 

✔ 4–6 weeks – Noticeable jawline slimming and facial contouring. 

✔ 8–12 weeks – Full results, with a smaller, more sculpted jawline. 

How Long Do the Effects Last? 

Results typically last 4 to 6 months, depending on your metabolism and muscle activity. 

✔ For long-lasting results, maintenance treatments every 4–6 months are recommended. 

✔ With continued treatments, the masseter muscle remains smaller over time, leading to less frequent top-ups. 

Benefits of Masseter Relaxation for Jaw Slimming 

✔ Non-surgical & minimally invasive – No need for incisions, anaesthesia, or long recovery times. 

✔ Natural-looking results – A gradual jaw slimming effect without an unnatural, "overdone" look. 

✔ Reduces pain & tension – Helps those suffering from bruxism, teeth grinding, and jaw discomfort. 

✔ Quick & convenient – A 10–15 minute procedure with no downtime. 

✔ Long-lasting effects – Results last for several months, with continued improvement over time.
