A large or square jaw is often caused by overly developed masseter (chewing) muscles, which add bulk to the lower jaw. Jaw-slimming injections work by relaxing and reducing the size of these overdeveloped chewing muscles. As these muscles relax the face becomes slimmer and the jaw develops a softer angle. Many patients find this treatment makes them look less aggressive, giving them a less tense, friendlier appearance. For ladies, it creates a more heart-shaped feminine face and for men, it corrects any excess bulk in the area that may have been caused by teeth grinding. We are also able to correct any asymmetries caused by clients chewing only on one side.

At NU-U, we use a special toxin to relax the overdeveloped muscles and reshape your face. This treatment has become popular among those looking for a fast change in their appearance without a significant recovery period. After about 3 weeks treatment will have changed the angular nature of a Jaw and your face will look slimmer.

This treatment is suitable for those with masseter muscles that are enlarged. Individuals with large bone structures in their jaw will not benefit from this and other treatments may be more suitable. Our experienced Doctors will discuss this with you at the initial aesthetics planning consultation.


I cannot recommend NU-U highly enough. I have had my “Vampire Facelift” done by both Dr Rai and Dr Punater and each time it has had an amazing effect on my skin. I’m so glad I have found these doctors. They are welcoming and know exactly how to make your skin so much more radiant.

Excellent. I went to NU-U just before my wedding due to some frown lines. My treatment was amazing start to finish. Everything I was worried about was carefully looked at and precisely corrected.

PRP here is the best I’ve ever had! I have to get PRP done on my hair following a hair transplant. Lots of my friends have had very painful experiences with scalp PRP. Dr Rai does my treatment with a fast machine and it is so much better than the places I visited in London.

Excellent service. I’ve had several different treatments from Dr Punater at NU-U. Each one has given great results and I’ve been amazed at how easy he makes everything look. This is definitely the best place I have been to for cosmetic treatments.

From the moment I was greeted by Dr Rai I felt I was in safe hands. This is an amazing clinic where they really aim to look after you and I wouldn’t trust anyone other than Dr Rai now. The injections I had were far less painful and gave a much better result than anywhere I’ve been before. Would highly recommend NU-U to everyone.

Great Professional Service! I felt at ease with these guys. Very caring, professional and explained everything to me. Gave me my options and guided me through what would be best for my skin. I’ve not been to other clinics and having chosen this one I don’t think I’d ever go anywhere else.
