A Botox jaw muscle treatment can be helpful if you have a wide jaw caused by an overactive masseter muscle. During the procedure, Botox is injected into the masseter the muscle located along the jawline. The results typically last around 3 to 6 months, after which you can choose to repeat the treatment if you wish.

For many people, seeing real results is an important step before deciding on masseter Botox. Below, you can view before-and-after photos from patients who have undergone this treatment. These images show the jawline both before and after Botox. All photos have been provided by clinics listed on Injectablesbooking.co.uk, with full consent from the individuals treated.

Why Before-and-After Photos of Jawline Botox Treatments?

Before-and-after photos are a useful way to get an impression of how a masseter Botox treatment can look. They help you decide whether the results align with your expectations and give you a clear idea of the potential outcome. It’s important to remember that every face is unique. Results will always vary from person to person, so the photos should be seen as a guideline rather than a guarantee.

Why You Shouldn’t Compare Yourself to the Photos

Each individual responds differently to masseter Botox. Factors such as facial anatomy, muscle strength, and how the body reacts to botulinum toxin play a role. Comparing yourself to someone else’s results may create unrealistic expectations. When making your decision, take time to reflect on your own reasons for treatment. Don’t rely solely on photos also consider the clinic’s expertise, consultation advice from the practitioner, and independent reviews from other patients. This ensures you make a well-informed choice you’ll feel confident about.

Step-by-Step Guide to Choosing a Jawline Botox Treatment

  1. Select a few trusted clinics in your area.

  2. Book a consultation with the practitioners.

  3. Take your time before committing to treatment.

  4. Make your decision when you feel fully ready.

  5. Follow the clinic’s aftercare instructions and review your results.

Botox Jawline Treatment Before and After Results

Do you want a slimmer jaw that will give your face a more defined look? Then a jaw muscle treatment is perfect for you! Slimming the face is also known as face slimming in medical terms. The Botox treatment results in a slimmer face. The muscle is temporarily numbed, causing it to lose strength and the jaw to shrink.

What does a Botox treatment for your jaw look like? The treatment consists of 3-5 injections in the large jaw muscle (masseter muscle) or the other chewing muscle (temporal muscle). Your jaw will continue to function, but jaw clenching will be a thing of the past. This treatment lasts for 3-4 months, after which you can choose to have it repeated.

Another option is jawline fillers. Jawline fillers hydrate and stimulate the skin, making it firmer. In this treatment, the filler is very subtly injected into the jawline, lifting the skin. This treatment remains visible for one year, after which you can choose a new treatment.

Finding a trustworthy and reliable aesthetic clinic can be difficult, but I’m so glad I discovered this one, conveniently located in the centre. I visited for a consultation about hair loss and dark circles under my eyes.

I met Maria, who was absolutely lovely—very knowledgeable, professional, and skilled. I had PRP treatment for my hair and Polynucleotide injections for my under eyes. During the consultation, I also decided to try Morpheus8 on my neck for a more defined and sharper jawline.

All of the treatments went smoothly, and Maria made me feel completely comfortable throughout.
I already noticed baby hair started growing and my neck definitely look tighter!
I trust her expertise and will definitely be coming back again. Highly recommend this clinic and Maria! Show less »

Today was my first time getting dermal filler and I was very nervous but Amo was reassuring and explained everything to me to put me at ease. Like she said, the procedure wasn’t painful and she checked on me throughout. She was professional and the clinic was clean and comfortable.

My jawline is much more defined now still but looks very natural and subtle even right after being done.

I’m excited to see the results in the next two weeks as the filler settles! Show less »

I can already see a big difference in my skin. The tightness and glow are so noticeable, and my jawline has improved significantly after just one treatment. Honestly, I didn’t expect to see such quick results, and I’m absolutely impressed.

I can’t wait for my next treatment – thank you, Janette, for making this such a wonderful experience! Show less »
I had Botox full face and neck this year to address lines and wrinkles which were bothering me. I now come regularly and have seen a massive improvement in my face. Today I had filler in my jawline which has given me more definition back and improved laxity. Cheers

Dr Sarah Tonks expertise and approach are second-to-none. I cannot recommend The Lovely Clinic more for anyone wanting to address cosmetic, facial balancing or anti-ageing concerns.

In one visit, Dr Tonks solved: teeth grinding (bruxism) with botox, a gummy smile with a lip flip, poor skin issues with personalised product recommendations and prescriptions for medical-grade skincare, under-eye darkness with sunekos skin booster, and volume loss/ sagging skin with JULAINE biostimulator. She also recommended a Nefertiti neck lift to improve my neck and jawline, which was done alongside a toxin brow lift. All of this has had immediate effects which are getting better over time (it has only been a few weeks since my appointment!)

The medical aesthetic clinic is in a wonderful location in Chelsea, very easy to get to from tube or bus. I was greeted warmly and felt comfortable before I even entered the building thanks to great pre-appointment messages.

Overall a fault-less experience. It was a pleasure to put my trust in the expert and be guided in which treatments would benefit me the most. If you're on the fence about visiting, just do it! You will not regret a visit to The Lovely Clinic in London. Show less »

What sets this clinic apart is the holistic approach to wellness and spirituality. I absolutely love the kundalini yoga and breath work sessions that perfectly complement the aesthetic treatments. It’s a wonderful way to balance skin body and mind. Plus, finishing off with the red light therapy sauna or cryotherapy really enhances mental clarity.

I feel so grateful to have found this clinic and highly recommend it! Show less »

What to consider when choosing a clinic

Choosing a clinic is one of the most difficult decisions for many people when choosing a Botox jawline treatment. We've listed the most important considerations.

Price: The average price of a Botox jawline treatment is between £160 and £340. When choosing a clinic, it's important to find a price somewhere between these two to ensure high quality.

Reviews: Reviews are invaluable for a clinic. A clinic with many good or bad reviews can indicate good or poor results.

Appearance: What is the clinic's appearance and how professional its website looks? These are indicators of the quality of the treatment.

Impression: What is your impression of the clinic and how you are treated, for example, during a consultation? Always consider carefully before choosing a clinic whether it's the right one for you. When making a decision, choose the clinic that shows the best results, but also follow your gut. Never make a choice that doesn't feel right.
