Anti-wrinkle injections or Botulinum Toxin is a chemical typically used in facial muscles to treat wrinkles such as lines on the forehead, frown lines and crow’s feet. It has been used for this purpose for over 20 years.

At NU-U Clinics in Maidenhead we use a brand of botulinum toxin called Azzalure®. This is a widely used, pure and highly tested brand that is recommended by Doctors all over the world due to its great safety profile and its long-lasting effects. Azzalure® is used for both cosmetic treatments and in hospitals for medical treatments.

Our Experts

Our Doctors at NU-U Clinics in Maidenhead have advanced training in facial anatomy and injection techniques which allow us to achieve the desired effects consistently and safely. We aim to create a natural, more youthful look which is achieved by our experience and skill. We use Azzalure® cosmetically for Crow’s feet, Dimpled chin, Drooping mouth corners, Forehead lines, Frown lines, Gummy smile, Jaw pain, Vertical lip lines and a Wide jaw. Our doctors also use it to treat Hyperhidrosis (excessive sweating) anywhere on the body, Migraines, Muscular neck pains, Teeth grinding and Tension headaches. We are experienced in treating the anatomy of both men and women and this experience ensures our clients look natural.

What to expect

Small quantities of Azzalure® are injected into selected facial muscles with a very small fine needle. This relaxes the muscles, thereby smoothing out of the skin and it minimises creases, lines and wrinkles. If used regularly botulinum toxin can lead to fewer wrinkles forming over time, thus keeping a youthful look for longer even after the use of this treatment has ceased. When used in other areas of the body (e.g. the armpit) the same treatment is used to resolve excessive sweating (also known as hyperhidrosis). Small amounts of Azzalure® are injected to stop the glands from producing sweat.

After Care

We review our aesthetics clients after 3 weeks to ensure they are completely happy with the results. The treatment usually takes around 2-3 weeks to have its maximal effect and lasts approximately 3-4 months in facial muscles but much longer in sweat glands.

We recommend not applying excessive heat to the area treated and not rubbing the area too much as this may dilute the effect of the treatment. If there are any small adjustments a client wants this can be done at the review appointment and these are usually undertaken without further charge.



Am I eligible for this treatment?

These injections can be used on most people, with the most popular uses being for the reduction in forehead lines and crows’ feet. A medical history is taken prior to treatment and we will check that it is safe for you to proceed.

Patient who have nerve problems or muscle problems should let us know prior to treatment so we can advise. Treatment is not undertaken for pregnant or breastfeeding women.

How safe is Botulinum Toxin?

In high concentrations botulinum toxin is a potent poison. However, when used in small doses by a trained professional, as it is in aesthetic medicine, has a very high degree of safety and an excellent safety record.

Are there any side effects?

Side effects of this treatment are rare. Occasionally a temporary drooping of the eyelid can occur. This may last a few weeks, but will always resolve and we take all possible precautions to reduce the risk of this. Special eye drops can be prescribed during this time to help lift the lid back into the normal position in the rare case that this happens. In extremely rare cases patients have developed an allergy to the treatment, while others have shown resistance, i.e. it causes little or no effect on the treated muscles.


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.

— Mina

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.
