Understanding a square jaw

A square or wide lower face is often caused by an enlarged masseter, the muscle you use to chew. Easing this muscle slims the jaw over a few weeks and can also relieve clenching. It applies the principles behind our anti-wrinkle injections to the shape of the lower face.

What causes a wide jaw

The masseter muscle can grow larger through genetics, habitual clenching or grinding, widening the angle of the jaw. A larger muscle gives a squarer, heavier lower face. This is different from a wide jaw caused by bone structure.

Who tends to notice it

People who clench or grind, often through stress or at night, tend to develop a stronger masseter. It is common in those who want a softer, slimmer lower face, and in people whose jaw feels tight or aches from clenching.

A prescription injectable eases the masseter so it gradually reduces in bulk, softening a square jaw over a few weeks.
Alongside slimming, a little jawline filler can refine the shape of the lower face where you would like more definition.

What results are realistic

Where the width comes from an enlarged muscle, a gradual, natural slimming over a few weeks is realistic, and clenching often eases too. If the width is mainly from bone structure, this treatment will not change it, and we will tell you so honestly at consultation.

I can’t recommend Rachel highly enough. This was my very first appointment with Rachel and it certainly won’t be my last, she made me feel completely comfortable and at ease. She is incredibly professional, knowledgeable, and takes the time to really listen and understand what you want to achieve. Rachel has a very natural approach and her attention to detail is amazing. I feel confident knowing I’m in such skilled hands, and the results have been exactly what I hoped for. Thank you, Rachel, for your care, expertise, and for always making the whole experience so positive. I wouldn’t hesitate to recommend you to anyone looking for a trusted and talented practitioner.

I recently had polynucleotide under-eye injections with Rachel, and I couldn’t be more pleased with both the experience and the results so far. From the moment I arrived, Rachel was incredibly welcoming, professional, and knowledgeable. She took the time to explain the treatment thoroughly and made me feel completely comfortable and reassured throughout the entire process. The treatment itself was surprisingly pain-free, with minimal discomfort and very little downtime afterwards. I’ve already noticed a significant improvement in the appearance of my under-eye area - it looks brighter, more refreshed, and the fine lines have softened noticeably. As someone who works night shifts in the NHS, tired-looking eyes have always been a concern for me, so seeing such positive results already has been amazing. I’m excited to complete the rest of my treatment course and see the full benefits. I would highly recommend Rachel to anyone considering polynucleotide treatments. Her professionalism, expertise, and friendly approach make the whole experience exceptional ❤️
