A Botox treatment for the jaw muscles may help 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. Results typically last 3 to 6 months, after which you may choose to repeat the treatment if desired.

For many patients, viewing real results is an important step before deciding on masseter Botox. Below, you can browse before-and-after photos from individuals who have undergone this treatment. These images show the jawline before and after Botox. All photos are 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 provide a helpful way to understand how a masseter Botox treatment may look. They give an indication of potential results and help you decide if the treatment aligns with your expectations. It is important to remember that every face is unique. Outcomes vary between individuals, so these photos should be used as a guide rather than a guarantee.

Why You Shouldn’t Compare Yourself to the Photos

Each person responds differently to masseter Botox. Factors such as facial anatomy, muscle strength, and the body’s response to botulinum toxin influence results. Comparing yourself to others may create unrealistic expectations. When deciding on treatment, consider your own reasons, the clinic’s expertise, consultation advice from the practitioner, and independent patient reviews. This ensures a well-informed decision you 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 a qualified practitioner.

  3. Take time to consider your options before committing.

  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

If you are looking for a slimmer, more defined jawline, a jaw muscle treatment may help. Medically referred to as face slimming, Botox can temporarily reduce muscle strength in the masseter, giving the jaw a softer contour.

Treatment typically involves 3–5 injections into the masseter or temporal muscle. Jaw function continues, but habitual clenching is reduced. Results generally last 3–4 months, after which repeat treatment is optional.

Jawline fillers are another option. They hydrate and stimulate the skin, providing lift and firmness. The filler is subtly injected along the jawline, with results lasting up to one year, after which a follow-up treatment can be considered.

I had Endolift at Cosmedocs three days ago and wanted to share my experience because I was extremely nervous beforehand. After reading some scary reviews online about swelling and recovery, I was honestly quite anxious about going ahead with the procedure. However, if I was going to trust anyone with this treatment, it would be Dr Haq at Cosmedocs.
From the moment I arrived, both Dr Haq and the team made me feel completely at ease. The care, patience and attention I received throughout the appointment were outstanding. Everything was explained clearly, and I never felt rushed or pressured at any point. Dr Haq’s calm and professional manner really helped ease my nerves, and the team were incredibly kind and reassuring throughout. I genuinely felt comfortable the entire time and the whole experience was far more pleasant than I expected.
It’s probably still a little early to comment on the final results, but three days post-treatment I can barely notice any swelling.
For comparison, I experienced much more swelling previously from jawline filler and PDO threads than I have from this treatment.
Overall, I just wanted to thank Dr Haq and the Cosmedocs team for the professionalism, warmth and care they showed me during the whole experience. It made a huge difference to how relaxed and confident I felt going into the procedure. I’m very excited to see the final results over the coming weeks and would happily recommend Cosmedocs to anyone considering treatment. Show less »

Just had an endosculpt treatment on my lower face and jawline today . I’m completely bowled over with the results and Maria told me this can only improve over the next few months . Have been to Maria for quite a while now for other treatments and can honestly say I completely trust her advice and work . The clinic is beautiful and would highly recommend.

I recently visited London Lip Clinic for full face rejuvenation ahead of my 40th birthday, and I’m genuinely so happy with the results.
Rupesh was very thorough during the consultation, looking at my facial structure, skin quality and overall balance. He is clearly very knowledgeable and medically trained but also so friendly and easy to talk to, which made me feel completely at ease, which is exactly what I wanted.
He used dermal fillers from the Revanesse range, which are known for causing less swelling and inflammation while still giving very natural looking results. In total he used 7 syringes to lift my cheeks and mid-face, define my jawline and chin, soften the lines from my nose to mouth and the lines around my mouth, and subtly enhance my lips. The result is fresh and lifted but still completely me.
He used both cannula and needle techniques and explained everything clearly, so I felt safe and confident throughout. The aftercare has been great too.
If you’re considering full face dermal fillers in London, especially on Harley Street, I would definitely recommend London Lip Clinic. Professional, natural results and a really positive experience. Show less »

To say I’m obsessed and so happy would be an understatement! From the moment I stepped in for my initial consultation I was immediately put at ease with Sarah’s expertise. Her client is stunning and absolutely spotless and I knew she was the girl for me.
I’ve just had my first appointment for Botox and Tear Trough Filler and the results are way beyond what I had hoped for. We added in some collagen threads and some additional filler and Botox on my lower face, the outcome, instantly brighter eyes and a defined jawline!
Sarah is so particular and gentle, the entire process was painfree and simply stunning.
Thank you Sarah, you are absolutely amazing 🥰 Show less »

I recently noticed my neck losing firmness and aging faster than my face, so I visited Katie to explore options before considering any drastic surgery. We decided on four Sunekos treatments, and I’m genuinely amazed by the results—it’s even improved my jawline. I don’t usually write reviews, but if this helps anyone looking for some rejuvenation (it works on the face, neck, chest, and hands), it’s painless with only about an hour of downtime for me and last for about a year. I started seeing improvements after the second treatment—no turkey neck here! Thank you K Govind xxx Show less »

Catherine is amazing I go to her for Botox and jawline filler and always so pleased with the results I would definitely recommend her xx

Had PDO threads for a subtle lift and I can already see the difference. Bit tender for a few days but totally worth it. My jawline looks more defined and my face feels tighter without looking fake.

I’m really happy with my jawline results. I honestly loved how it turned out it looks sharper and more defined, exactly what I was hoping for. The whole process was smooth, and I felt well taken care of. I definitely recommend it, and I’m very satisfied with the final result.
